Denver HVAC Repair

Once a diagnosis is made to your air-conditioning and/or heating system, the unit can be repaired, in most situations, with stock HVAC parts off the truck. Sometimes the HVAC part has to be ordered because it is a specialty part that only the HVAC manufacturer of your equipment can provide. If the part can be picked up locally then you can expect to pay for travel time to and from the HVAC parts dealer. It is practically impossible to carry every single HVAC part for every single HVAC breakdown that occurs.

At Brennan’s Heating & Air Conditioning, we still provide good, old-fashioned service, but we also offer the full line of cutting-edge products from the heating and cooling experts at Carrier.
When seeking emergency heating or cooling services you want experts that actually care about the results and your comfort. You want to choose the HVAC company in Alexandria with extensive skill and top-class tools, but you don’t want them to take advantage of your bad situation! With HVAC Unlimited, you never need to worry. We make it our mission to offer superior services any time you need it, and we guarantee cost-efficient solutions that restore your comfort.

If the condenser coils are clogged, the compressor can overheat and shut down. You’ll experience intermittent periods of minimal cooling, followed by no cooling. Even if you’re “sure” the condenser coils are clean, clean them again. Turn off the power. Flip the air conditioning service and furnace circuit breakers in your main electrical panel to the “Off” position. Next, turn off the power switch right at the furnace or air handler. Then yank the disconnect block (Photo 1) and clean the condenser coils (Photo 2). If the air conditioning service still doesn’t work properly after you’ve cleaned the condenser coils, installed a new filter and opened all the supply vents, proceed with the following repairs.
HVAC pros are busy, especially in the summer. Just because you need an AC repair right now, that does not mean an HVAC pro will be available. Additionally, if they are free, your cost to repair the AC unit just went up. Emergency situations call for changes in schedules, surprise road trips and many other sudden situations. As such, air conditioning contractors tend to charge more.
Other than mineral deposits, the most common problem is sediment in the water supply. The float inlet valve has a tiny hole that easily clogs. The float is usually made of plastic, and if cracked will fill with water and sink. The valve will be stuck open and the reservoir will overflow. Use caution when scraping deposits off the float. If the deposits cannot be removed, replace the float or it will sink and cause an overflow.

Some service providers may recommend repairs and maintenance tasks that are not needed. A savvy consumer who has researched how an HVAC system works and is familiar with most common maintenance tasks will quickly know the difference between necessary tasks and add-on services that drain the wallet. If a heating or cooling problem occurs, appliance service manuals typically contain troubleshooting tips and other information that may be helpful in identifying or even resolving the problem without calling a repairman. Online HVAC guides may also be helpful to a consumer who wishes to become more familiar with how an HVAC system works and potential signs of disrepair. 
Modern refrigerants have been developed to be more environmentally safe than many of the early chlorofluorocarbon-based refrigerants used in the early- and mid-twentieth century. These include HCFCs (R-22, as used in most U.S. homes before 2011) and HFCs (R-134a, used in most cars) have replaced most CFC use. HCFCs, in turn, are supposed to have been in the process of being phased out under the Montreal Protocol and replaced by HFCs such as R-410A, which lack chlorine.[14] HFCs, however, contribute to climate change problems. Moreover, policy and political influence by corporate executives resisted change.[15][16] Corporations insisted that no alternatives to HFCs existed. The environmental organization Greenpeace provided funding to a former East German refrigerator company to research an alternative ozone- and climate-safe refrigerant in 1992. The company developed a hydrocarbon mix of isopentane and isobutane, but as a condition of the contract with Greenpeace could not patent the technology, which led to its widespread adoption by other firms.[17][18][19] Their activist marketing first in Germany led to companies like Whirlpool, Bosch, and later LG and others to incorporate the technology throughout Europe, then Asia, although the corporate executives resisted in Latin America, so that it arrived in Argentina produced by a domestic firm in 2003, and then finally with giant Bosch's production in Brazil by 2004.[20][21]

There is nothing worse than having your air conditioner break in the middle of a long, hot summer. You can ensure your air conditioning unit stays in working order all year long with regular service. Sometimes, however, repairs are necessary whether it’s fixing the evaporator, capacitor, or condenser or recharging the refrigerant. Most air conditioner repairs cost between $163 and $528 with most homeowners reporting that they spend about $344. If you do need a repair, here is some information to help you get it done quickly, professionally, and economically.

Special chemicals can be used to clean mineral deposits, but one of the safest is vinegar. A 50% mixture of vinegar and water will usually dissolve or help clean away deposits. If the humidifier has a drum with a belt, replacement of the belt at the beginning of the heating season can be the easiest fix if the water has a high mineral content. If the humidifier has screens or is the wick type, some corrosion can occur as well as build up

Regardless of the scope of your project, find out what you need to do to prepare your home for their visit. For example, the HVAC professional will need access to the areas in question and may need access to other mechanical or ventilation points. Make sure pets and children are kept out of the way. Ask if your project will involve removing dry wall or making any other structural changes – you may need to hire a professional drywall contractor to patch up HVAC work. If you are adding a unit that may contribute to carbon monoxide within the home, find out if you need to purchase a carbon monoxide detector.
Clean air delivery rate is the amount of clean air an air cleaner provides to a room or space. When determining CADR, the amount of airflow in a space is taken into account. For example, an air cleaner with a flow rate of 100 cfm (cubic feet per minute) and an efficiency of 50% has a CADR of 50 cfm. Along with CADR, filtration performance is very important when it comes to the air in our indoor environment. Filter performance depends on the size of the particle or fiber, the filter packing density and depth and also the air flow rate.[26]

a/c compressor needed replacing. the A Team Mechanical found a way to return the next day to complete the repairs and made sure the system was running effectively. Even put down another concrete base pad to level the a/c unit. They were professionals and straight forward with the services needed. All the other HVAC companies wanted to charge me three time the amount for the services.

If the AC doesn’t turn off, it may be time to clean the condensing unit. Dirty condenser coils won’t give off heat efficiently and will keep the unit running.  Another possibility: The contacts on the outdoor run relay may have welded together—something that can happen over time because of frequent electrical arcing at the relay. Before checking the run relay, turn off the power to the furnace and the condensing unit. Next, disassemble the relay and pry apart the contacts. This should do the trick until you buy a replacement—which you should do soon.
Since the 1980s, manufacturers of HVAC equipment have been making an effort to make the systems they manufacture more efficient. This was originally driven by rising energy costs, and has more recently been driven by increased awareness of environmental issues. Additionally, improvements to the HVAC system efficiency can also help increase occupant health and productivity.[20] In the US, the EPA has imposed tighter restrictions over the years. There are several methods for making HVAC systems more efficient.
In variable climates, the system may include a reversing valve that switches from heating in winter to cooling in summer. By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa. This allows a facility to be heated and cooled by a single piece of equipment by the same means, and with the same hardware.

The manufacture and use of CFCs has been banned or severely restricted due to concerns about ozone depletion (see also Montreal Protocol).[63][64] In light of these environmental concerns, beginning on November 14, 1994, the U.S. Environmental Protection Agency has restricted the sale, possession and use of refrigerant to only licensed technicians, per rules under sections 608 and 609 of the Clean Air Act.[65]
Believe it or not, the evaporator coils inside the AHU (Air Handling Unit) are freezing. You may notice the refrigerant lines on the condenser or at the AHU are frozen with ice build-up. The frost or ice builds up on the evaporator coils and blocks air flow (low air flow and no cooling are a sign of a low charge). A low refrigerant charge will cause the evaporator coil to operate at or below freezing. Since the coil typically operates below the dew point, it draws condensation out of the air. When the evaporator coil begins operating below freezing all this condensation freezes to the evaporator coil and the unit stops cooling.

Eventually, every homeowner experiences a malfunction in their heating unit. It’s a cold morning and you hike the thermostat up like you usually do to take the chill off, but you get no response. You don’t hear the system firing up or feel the radiators or air vents producing any heat. You hope it’s just a quick fix, like a clogged filter or a tripped circuit breaker. On the other hand, you might be wondering if it’s more cost-effective to just have the unit replaced.

Change your air filter. Air filters need changed every 30 to 90 days, depending on the type of filter you have. It’s a wise idea to get on a regular schedule – note filter changes on your calendar, and make a note to check them every month during the summer, when your system runs ‘round the clock. Follow these filter change instructions to get the job done.

In the refrigeration cycle, heat is transported from a colder location to a hotter area. As heat would naturally flow in the opposite direction, work is required to achieve this. A refrigerator is an example of such a system, as it transports the heat out of the interior and into its environment. The refrigerant is used as the medium which absorbs and removes heat from the space to be cooled and subsequently ejects that heat elsewhere.
Finally, air conditioning and heating maintenance, provided on a regular schedule, can prevent many air conditioner or heater breakdowns thereby preventing the need for you to call an air conditioning and heating repair person for central air conditioning troubleshooting. Maintenance can save you lots of money in the long run but even so, problems can still occur.
The liquid refrigerant is returned to another heat exchanger where it is allowed to evaporate, hence the heat exchanger is often called an evaporating coil or evaporator. As the liquid refrigerant evaporates it absorbs energy (heat) from the inside air, returns to the compressor, and repeats the cycle. In the process, heat is absorbed from indoors and transferred outdoors, resulting in cooling of the building.

The myth that most people believe is that if you add more refrigerant to the unit it will cool better. This is only true if the evaporator coil is operating below freezing. The unit must have a balanced charge at the correct refrigerant pressure for the temperature and usually, only an HVAC professional can charge your unit properly. Another misconception about refrigerant is that the unit burns it up and it must be replaced from time to time. This is not true. Furthermore, the refrigerant loop is a closed system and barring any leaks the air conditioning system should never need any refrigerant.

Low refrigerant charges take away from the life of the compressor. The compressor is cooled from the return refrigerant vapor. When there is a low charge there are fewer vapors to cool the compressor, therefore it runs hotter. Any compressor (or electric motor for that matter) which runs above the recommended temperature range will have a shorter life span and cost more to operate.
Air conditioning units work by using evaporator and condenser coils to remove heat from the air in your home. Warm household air blows through the evaporator coils, which transfer the heat into refrigerant vapor, which is then moved to the condenser in the outdoor part of the unit. The condenser coils turn the now-warm refrigerant vapor into liquid, allowing the heat to be dispersed outside and away from your home.
From Day 1, Alberto walked us through the process, and present us with a variety of options based our budget for the project. His customer service is the best as he did not oversell any services and did not nudge us towards buying a unit that would stretch our budget. On installation day, HVAC Services sent out a crew of 6-7 guys, all of whom were very polite and kept their work areas clean, and installed the whole system the same day.

In 1992, a non-governmental organization, Greenpeace, was spurred by corporate executive policies and requested that a European lab find substitute refrigerants. This led to two alternatives, one a blend of propane (R290) and isobutane (R600a), and one of pure isobutane.[18][22] Industry resisted change in Europe until 1993, and in the U.S. until 2011, despite some supportive steps in 2004 and 2008 (see Refrigerant Development above).[27][67]

The condenser coils turn the now-warm refrigerant vapor into liquid, allowing the heat to be dispersed outside and away from your home.
Most modern air-conditioning systems feature a dehumidification cycle during which the compressor runs while the fan is slowed as much as possible[citation needed] to reduce the evaporator temperature and therefore condense more water. When the temperature falls below a threshold, both the fan and compressor are shut off to mitigate further temperature drops;[clarification needed] this prevents moisture on the evaporator from being blown back into the room.[citation needed] When the temperature rises again,[clarification needed] the compressor restarts and the fan returns to low speed.
The use of CFC as a refrigerant was once common, including the refrigerants R-11 and R-12 (sold under the brand name Freon-12). Freon refrigerants were commonly used during the 20th century in air conditioners due to their superior stability and safety properties. When they are released accidentally or deliberately, these chlorine-bearing refrigerants eventually reach the upper atmosphere.[60] Once the refrigerant reaches the stratosphere, UV radiation from the Sun homolytically cleaves the chlorine-carbon bond, yielding a chlorine radical. These chlorine radicals catalyze the breakdown of ozone into diatomic oxygen, depleting the ozone layer that shields the Earth's surface from strong UV radiation. Each chlorine radical remains active as a catalyst until it binds with another radical, forming a stable molecule and quenching the chain reaction.
An air conditioner’s cooling process produces condensation, which normally flows away from the equipment, causing no problem. If there is a clog in the condensate drain lines or drip pan, or if outdoor humidity levels are high, moisture may back up into your air conditioner. Excess condensation will increase indoor humidity levels and hinder the air conditioner’s performance. It could also cause damage to your air conditioner’s components.
HVAC services is our go to contractor when it comes to our HVAC needs. Back in 2013, we were dealt some unforeseeable home projects, as our HVAC was failing and needed to replace the whole system, e.g. Furnace, Blower, A/C, Condenser, Vents, etc... We reached out to a few HVAC companies (Contra Costa Heating and Air, EP builders, High Performance Heating and Air) so we could compare the bids for the job. We have had some issues with past contractors and after thoroughly screening a few of the above mentioned HVAC contractors, we awarded the bid to HVAC services because of their superior customer service and very reasonable pricing. From Day 1, Alberto walked us through the process, and present us with a variety of options based our budget for the project. His customer service is the best as he did not oversell any services and did not nudge us towards buying a unit that would stretch our budget. On installation day, HVAC Services sent out a crew of 6-7 guys, all of whom were very polite and kept their work areas clean, and installed the whole system the same day. Although it's been 2 years since we have had the HVAC system installed, HVAC Services continues to provide great customer services, coming out semi-annually to check on the HVAC system and adjusting the airflow within the house. Definitely recommend them!!!!
Free cooling systems can have very high efficiencies, and are sometimes combined with seasonal thermal energy storage so that the cold of winter can be used for summer air conditioning. Common storage mediums are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat-exchanger-equipped boreholes. Some systems with small storages are hybrids, using free cooling early in the cooling season, and later employing a heat pump to chill the circulation coming from the storage. The heat pump is added-in because the storage acts as a heat sink when the system is in cooling (as opposed to charging) mode, causing the temperature to gradually increase during the cooling season.

If you have a good HVAC contractor they should offer an annual preventive maintenance agreement where they will perform semi-annual maintenance, once in the Spring and once in the Fall, to service your heating and cooling system. The typical maintenance agreement usually guarantees the HVAC contractor will provide service and parts at a discount rate if the listed equipment fails. Some contractors will even give you after hours service with no extra overtime charge as is the case with most other customers.
The summers here in Alexandria can range from almost pleasant to downright brutal. And you know as well as we do that it’s those latter days when your central AC or heat pump will decide to go down! But you needn’t seek solace at the Waterfront or over at Cameron Run Regional Park. The secret to restoring your comfort lies with the certified specialists at HVAC Unlimited!
You haven’t had a ductwork inspection in years: According to PG&E, the average home’s ductwork leaks up to 30 percent of its air before it actually reaches your living space. That means you’re still paying for the energy used to cool the air—without getting the relief of a cool home. Hire a technician to come take a look at your system; they can perform what’s called a duct-leakage test, which measures how much air is escaping the system. If it turns out your ducts are faulty or have significant gaps, a technician should be able to seal them up or replace your pipes—meaning you might not need a complete system overhaul. However, keep in mind that modern HVAC units are almost always more efficient thanks to technology advancements. In the end, you have to weigh your options: will you need to perform repairs each month?

They were quick to come out and diagnose the problem with my furnace, but I thought the estimate of $549 a bit high to replace the circuit board.  So called around and found Leo's Appliance in Concord that sells appliance parts and the circuit board was only $90.49 - that is the retail cost to me, so I imagine the wholesale cost is a lot less.  So BEWARE of this company since they wanted $500!!! to replace the circuit board which is located right in the front of the furnace - extremely easy to access.  I hate it that you cannot trust repair companies.
In the fall you should prepare your HVAC unit for winter. Turn off your air conditioner’s circuit, then hose it off to remove debris. It must dry completely. Do this when it’s warm enough that there’s no risk of the water freezing. Cover the exposed pipes with foam pipe insulation ($1-$3), and protect your entire unit with a weatherproof cover ($20-$50).
Most of the time, diagnosing problems is simple and other times it can be a complicated process where the HVAC technician calls in another HVAC technician. The technician may call in an HVAC manufacturer representative. Residential and commercial heating and cooling is important and you want the best possible HVAC air conditioning and heating service. It does not matter whether you have a Carrier Air Conditioner, Trane Air Conditioners, or need a replacement, whatever, it is best to get a qualified technician to look at your system before a decision is made to repair or replace the air conditioner or heat pump systems.
If your compressor doesn’t have an overload button and you hear it humming or buzzing, poke a screwdriver or stick down through the top grille and try to spin the fan blades clockwise. If doing this gives the fan enough of a boost to get it going, the unit has a faulty capacitor that must be replaced. See How to Test and Replace an AC Run Capacitor, above.
Was not satisifed with this company. This person came out and took 10 minutes only to tell me that my unit would not last for a year and that I needed to have it replaced! I'm not sure if he was very knowlegable or if he was just plain lazy and do not even try to fix the problem. He just wanted to install a brand new system because he was both and of course, that's much more money for him!

By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa. This allows a facility to be heated and cooled by a single piece of equipment by the same means, and with the same hardware.

Fall is here and winter right around the corner which means soon you will be using your furnace day in and day out. With that said, you cannot expect your heating system to perform at peak levels and provide you with all the warmth and comfort you need if you do not take time out to schedule routine maintenance or an immediate furnace repair should you discover a problem with your system exists.

Your system is 10 - 15 years old: Follow this simple rule of thumb from Energy Star—if your current system is over 10 years old, it's time to start looking into an HVAC replacement. Most HVAC systems last for about 15 years, so there’s no immediate need to replace yours if it’s still functioning properly. But by doing your research now, you’ll know just what you want to do should your HVAC system suddenly stop working properly.

Whether you’re starting your air conditioner for the first time this year, or a unit isn’t running properly and you need to service an air conditioner, following a few simple steps can save you time and money. While some service jobs should be left to a professional, there are several do-it-yourself fixes you can do to keep your air conditioner cooling all summer long.

This doesn't mean air conditioning isn't right for your home. Some people are more sensitive to heat than others. Even if you can't justify the expense of central air conditioning, window air conditioning units will allow you to cool individual rooms tailored for your needs. If you work from home, you may want to put one of these units in your home office. If you have trouble sleeping with even modestly warm temperatures, you may want to put one in your bedroom. If you love to cook and spend long afternoons using the oven, your kitchen may be the place.
HVAC services is our go to contractor when it comes to our HVAC needs. Back in 2013, we were dealt some unforeseeable home projects, as our HVAC was failing and needed to replace the whole system, e.g. Furnace, Blower, A/C, Condenser, Vents, etc... We reached out to a few HVAC companies (Contra Costa Heating and Air, EP builders, High Performance Heating and Air) so we could compare the bids for the job. We have had some issues with past contractors and after thoroughly screening a few of the above mentioned HVAC contractors, we awarded the bid to HVAC services because of their superior customer service and very reasonable pricing. From Day 1, Alberto walked us through the process, and present us with a variety of options based our budget for the project. His customer service is the best as he did not oversell any services and did not nudge us towards buying a unit that would stretch our budget. On installation day, HVAC Services sent out a crew of 6-7 guys, all of whom were very polite and kept their work areas clean, and installed the whole system the same day. Although it's been 2 years since we have had the HVAC system installed, HVAC Services continues to provide great customer services, coming out semi-annually to check on the HVAC system and adjusting the airflow within the house. Definitely recommend them!!!!
Its unique feature is the presence of one main external unit that connected to several indoor units. Such systems might be the right solution for maintaining the microclimate in several offices, shops, large living spaces. Just few of outdoor units do not worsen the aesthetic appearance of the building.The main external unit can be connected to several different indoor types: floor, ceiling, cassette, etc.
Before you service an air conditioner, make sure the unit is turned completely off by unplugging or shutting off the circuit breaker. Then, rake off any debris from the unit and use a soft brush to remove dirt from the outside cover. If the small copper pipe connecting the unit to the house feels hot, the unit’s coils likely needs to be washed. Remove the outside cover, cover the motor and wiring with a plastic sheet, and hose down the fins, coils, and inside of the unit. Finally, replace the cover when you’re done.
Poorly maintained water cooling towers can promote the growth and spread of microorganisms,[55] such as Legionella pneumophila, the infectious agent responsible for Legionnaires' disease, or thermophilic actinomycetes. As long as the cooling tower is kept clean (usually by means of a chlorine treatment), these health hazards can be avoided or reduced. Excessive air conditioning can have a negative effect on skin, causing it to dry out, and can also cause dehydration.[citation needed]
If your compressor doesn’t have an overload button and you hear it humming or buzzing, poke a screwdriver or stick down through the top grille and try to spin the fan blades clockwise. If doing this gives the fan enough of a boost to get it going, the unit has a faulty capacitor that must be replaced. See How to Test and Replace an AC Run Capacitor, above.
If your AC doesn’t turn off when room temperature reaches the temperature set on the thermostat, the problem is generally occurring either at the thermostat or in the electrical system that runs the outside condensing unit. You can use the AC’s circuit breaker to shut off the unit, but that should not be a permanent solution—circuit breakers are not designed to be used like light switches.

Turning to a source you know and trust is a solution many can rely on. Online review sites can be full of negative or glowing experiences – you don’t know who’s telling the truth on Yelp, you don’t know who they are! Your neighbor, coworker, or family member is someone you’ve built a relationship with. You trust their opinions on many subjects – local air conditioner repair is no different.”

The standards do not require you to change your existing central air conditioning units, and replacement parts and services should still be available for your home’s systems. The “lifespan” of a central air conditioner is about 15 to 20 years. Manufacturers typically continue to support existing equipment by making replacement parts available and honoring maintenance contracts after the new standard goes into effect.

Start with your utility company; they can help a great deal. Comparing previous bills isn't always a good measure, as the weather is never exactly the same month to month. Instead, if you take your energy bill and divide it by the square footage of livable space in your home, don't count areas like unfinished garages or basements -- you can calculate how much you are spending to heat or cool each square foot of your home. Your energy provider can tell you what the average cost per square foot is in your region for that same period of time so you can compare apples to apples.
