Denver HVAC Repair

The performance of vapor compression refrigeration cycles[23] is limited by thermodynamics. These air conditioning and heat pump devices move heat rather than convert it from one form to another, so thermal efficiencies do not appropriately describe the performance of these devices. The Coefficient-of-Performance (COP) measures performance, but this dimensionless measure has not been adopted. Instead, the Energy Efficiency Ratio (EER) has traditionally been used to characterize the performance of many HVAC systems. EER is the Energy Efficiency Ratio based on a 35 °C (95 °F) outdoor temperature. To more accurately describe the performance of air conditioning equipment over a typical cooling season a modified version of the EER, the Seasonal Energy Efficiency Ratio (SEER), or in Europe the ESEER, is used. SEER ratings are based on seasonal temperature averages instead of a constant 35 °C (95 °F) outdoor temperature. The current industry minimum SEER rating is 14 SEER.[24]
    Second, there are the diagnostics involved as well as the return trip to effect the actual repair. What about the hidden costs such as having the part picked up at the supplier, was this considered? As for the parts manager at our shop having wasted time tracking the part down, it often happens that we have to contact several suppliers to find parts especially during the recent cold spell when so many suppliers were out of stock of even the most common service items due to demand being so high.
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.

R22 (also known as HCFC-22) has a global warming potential about 1,800 times higher than CO2.[61] It was phased out for use in new equipment by 2010, and is to be completely discontinued by 2020. Although these gasses can be recycled when air conditioning units are disposed of, uncontrolled dumping and leaking can release gas directly into the atmosphere.
Additionally, new technology and government requirements are pushing manufacturers to build more energy efficient HVAC equipment. January 2006 we observed the end of 10 SEER units with 13 SEER air conditioning units mandated by the government. This only makes sense; however, with the higher efficiency, there comes complexity in the technology engineered into the equipment. A problem can be difficult to troubleshoot and diagnose and may require more time than the lower efficiency, less complex units.
Air conditioners often use a fan to distribute the conditioned air to an occupied space such as a building or a car to improve thermal comfort and indoor air quality. Electric refrigerant-based AC units range from small units that can cool a small bedroom, which can be carried by a single adult, to massive units installed on the roof of office towers that can cool an entire building. The cooling is typically achieved through a refrigeration cycle, but sometimes evaporation or free cooling is used. Air conditioning systems can also be made based on desiccants (chemicals which remove moisture from the air) and subterraneous pipes that can distribute the heated refrigerant to the ground for cooling.[2]
Should you experience a system breakdown, know that there are a few common causes of summer AC repairs. Below you’ll find a few of the most common ones AC repair technicians face each day throughout the warmer months. Having a better understanding of the troubles your system may face can help you feel more at ease with the AC repair process, and better comprehend the information given to you by your technician.

Two weeks go by and no phone call from HVAC Service regarding install date, or any update at all.  I call them to check in to see if they have put me on the schedule and when I can expect to have the AC installed.    You can tell by the discussion I had with the lady on the phone that they completely forgot about me and have not scheduled anything.  She says she needs to get in contact with the owner because she has no idea on the availability of the crane.  I was told that she would call me back by the end of the day with an update.  Surprise, surprise, no phone call.

The condensed, pressurized, and still usually somewhat hot liquid refrigerant is next routed through an expansion valve (often nothing more than a pinhole in the system's copper tubing) where it undergoes an abrupt reduction in pressure. That pressure reduction results in flash evaporation of a part of the liquid refrigerant, greatly lowering its temperature. The cold refrigerant is then routed through the evaporator. A fan blows the interior warm air (which is to be cooled) across the evaporator, causing the liquid part of the cold refrigerant mixture to evaporate as well, further lowering the temperature. The warm air is therefore cooled and is pumped by an exhaust fan/ blower into the room. To complete the refrigeration cycle, the refrigerant vapor is routed back into the compressor. In order for the process to have any efficiency, the cooling/evaporative portion of the system must be separated by some kind of physical barrier from the heating/condensing portion, and each portion must have its own fan to circulate its own "kind" of air (either the hot air or the cool air).

Packaged terminal air conditioner (PTAC) systems are also known as wall-split air conditioning systems.[36] They are ductless systems. PTACs, which are frequently used in hotels, have two separate units (terminal packages), the evaporative unit on the interior and the condensing unit on the exterior, with an opening passing through the wall and connecting them. This minimizes the interior system footprint and allows each room to be adjusted independently. PTAC systems may be adapted to provide heating in cold weather, either directly by using an electric strip, gas, or other heater, or by reversing the refrigerant flow to heat the interior and draw heat from the exterior air, converting the air conditioner into a heat pump. While room air conditioning provides maximum flexibility, when used to cool many rooms at a time it is generally more expensive than central air conditioning.

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.
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.

"Customer service was great, and the price was in-line with other places, and fast service. We had a whole replacement of the outside and inside. I would have liked to see a better install for the furnace and new thermostat - the new thermostat should have gone where the old one was, and even tho the new furnace was a tight fit, they didn't offer to come back and repair the case molding, or give me a discount on the damage done, and I believe they should have put a disconnect box on the outside of the home, to make it easier for any future repairs needed. Other than that, am very happy with the cooling and heating!"
In order to get the most out of your equipment, we highly recommend proper preventative HVAC maintenance. You’ll want to make sure from the outset that you have access to skilled and knowledgeable technicians who have been factory-trained to service your particular model, since different systems require different highly specific modifications. It’s advisable to find a reputable HVAC dealer in the Atlanta area that guarantees their work and offers annual service contracts to their customers to ensure necessary seasonal maintenance is always being performed regularly. Many times, timely adjustments and filter changes that are done on a regular basis can wind up saving you from breakdowns that always seem to occur right when you need your system the most.

Take germs, for example. The majority of people attempt to avoid these dangerous airborne, illness-causing organisms with hand sanitizer or by washing their hands regularly. But did you know that a old indoor coil in your own Mableton home can expose you and your family to fungi and bacteria in your duct systems? That’s why devices like the Ultraviolet Germicidal Light exist. They can help prevent the accumulation of germs in your home and allow you to breathe in clean air. Call us for a complimentary, in-home estimate to find out how we can install one of these in your duct system.


Good Evening HVAC Team, I deeply appreciate your team for getting back to me quickly yesterday evening so I could schedule an appointment for my gf's place(definitely something has been wrong for a while)-- The technician Alberto showed up within the 2 hour window that was appointed to us (WITHIN the 1st half hour!!!). BIG THANK YOU for being honest, and advising us that for some reason the fuse/switch was in the reverse position so the AC unit would not properly turn on. The unit turned back on immediately, and began cooling the house. And then providing advice that the AC/Heating system needed some TLC, and giving us options to save money by purchasing a maintenance plan that included the filters plus cleaning services since we were already being charged for the service today. My personal thanks for being extremely professional, and personable as you entered our home. Solving the technical issue is only part of the job, but providing great Customer Service, and Cost Effective solutions are reasons to recommend you to the people who are looking for the same type of service. Also, it was very convenient that you were able to take my payment over the Phone(FaceTime) since I was not present at the time. Your company website is well organized, and I had no problem reviewing your capabilities as well as how to contact your team. Most important, Tina spoke very highly of you, and made her feel comfortable through the process. SO BOTTOM LINE to other customers looking for HVAC service: LOOK NO FURTHER!!! If you have a AC/Heater Issue, give this the HVAC company a call, or email-- You won't be disappointed. Kind Regards, Michael

Air conditioning can also be provided by a process called free cooling which uses pumps to circulate a coolant (typically water or a glycol mix) from a cold source, which in turn acts as a heat sink for the energy that is removed from the cooled space. Common storage media are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter boreholes, equipped with heat exchanger. Some systems with small storage capacity are hybrid systems, 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 because the temperature of the storage gradually increases during the cooling season, thereby declining its effectiveness.
In the United States, HVAC engineers generally are members of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), EPA Universal CFC certified (for installation and service of CFC HVAC devices), or locally engineer certified such as a Special to Chief Boilers License issued by the state or, in some jurisdictions, the city. ASHRAE is an international technical society for all individuals and organizations interested in HVAC. The Society, organized into regions, chapters, and student branches, allows exchange of HVAC knowledge and experiences for the benefit of the field's practitioners and the public. ASHRAE provides many opportunities to participate in the development of new knowledge via, for example, research and its many technical committees. These committees typically meet twice per year at the ASHRAE Annual and Winter Meetings. A popular product show, the AHR Expo, is held in conjunction with each winter meeting. The Society has approximately 50,000 members and has headquarters in Atlanta, Georgia.
Air conditioning (often referred to as AC, A/C, or air con)[1] is the process of removing heat and moisture from the interior of an occupied space, to improve the comfort of occupants. Air conditioning can be used in both domestic and commercial environments. This process is most commonly used to achieve a more comfortable interior environment, typically for humans and animals; however, air conditioning is also used to cool/dehumidify rooms filled with heat-producing electronic devices, such as computer servers, power amplifiers, and even to display and store some delicate products, such as artwork.
Your air conditioner’s outside unit is home to the compressor, fan, and condenser coils. These components work to release heat from the air, transferring it out of your home to produce a cool indoor climate. When the outdoor fan isn’t working correctly, the heat transfer process is hindered. Not only will this prevent your air conditioner from adequately cooling your home, a broken fan can cause the system’s compressor to overheat. An overheated compressor could trigger the air conditioner’s safety controls, turning your air conditioner off; overheating can also cause damage to the compressor itself, requiring home AC repair or compressor replacement.
“We had a great experience with Robinson’s! The office staff, then the gentleman who helped me with questions over the phone and Kyle, our service tech, were all great and very easy to work with. They gave me a time frame for when to expect Kyle the same day. A phone call to let me know he was on his way. A text with picture so I knew who to be expecting. Kyle arrived on time and was very knowledgeable and friendly. He did a great job. You could tell he liked his job. Prices were reasonable. We will be using and recommending Robinson’s Air – Wichita Falls in the future.”

Stay away front his company!!! In 2008 I had the company send Rick a technician to do warranty work on my new house. I complained about my house being hot in the summer. Tech said that I had a delta t of 14 degrees (the difference of temp coming into the return and out the supply) and that system was functioning properly. Unfortunately I took their word. After 8 years of being hot I called a reputable company to come and check my system again. The HVAC system still operating with a delta t of 14 degrees. The new company looked at my HVAC system owner manual. They calculated my dry bulb temp and wet bulb temp and used the chart in the owners manual to determine that the system wasn't functioning properly. After the new company came a put two pounds of freon into my HVAC system I now have a 20 degree Delta t. Do not do business with this company not trust worthy!
Restoring or replacing an aging unit can get expensive. Invest in a new model if your utility bills are rising and you notice uneven air flow and temperatures throughout your property. If one room is cooler than another, consider a total replacement. If the air conditioner is relatively new and still within its age range, it's more cost-effective to get a contractor to repair it.
Change the filter: A new filter can cost as little as $20. Since this is the most effective way of maintaining your AC system, there is no reason not to change your filter. Homeowners should change your AC filters whenever it gets dirty. Depending on the filter, you may have to change it once every six months or once every month. Each filter should indicate how long it will last.
Routine maintenance involves replacing or cleaning the filters if so equipped, and keeping the outside air intake free of debris. After years of service the air exchanger will become crusted with grease and dirt that collects during condensation. Removing this accumulation will probably take solvents or degreasers and require opening up the cabinet and compartments.

If your air conditioner’s condenser coils, which are located in the outdoor unit, freeze up, your system will not run properly. Poor airflow through your cooling system can cause ice to form on the coils. Obstructions are typically the cause – such as dirty air filters or blocked return air ducts. Low refrigerant could also be the cause, requiring a refrigerant charge. A home AC repair technician can diagnose the issue behind your frozen coils, resolve it, and safely thaw your coils to restore cooling in your home.”
Finally, after the air conditioning unit has been properly charged, the unit should definitely cool better. There should be a temperature difference between the return and supply of 12° to 20° Fahrenheit (delta T). That range is generally acceptable for a proper delta T temperature. This dat is used to determine if your air conditioning system is operating efficiently. If you do not have this range of temperature differential with your air conditioning system then there are problems. These problems need to be addressed whether it is bad duct or a mechanical or electrical issue causing the problem. Lastly, the unit is simply not providing the cooling it needs to provide to make you comfortable.
Just like running a marathon, we perform better at full strength. If we’re not feeling great, it’s that much harder to finish the race. Similarly, when you set your thermostat to a certain temperature, the system is tasked with maintaining that temperature throughout the room. Working at full strength, the system can easily maintain that temperature (as long as it’s not below 60 degrees or above 80 degrees). However, when injured, the system may struggle to keep the room at your desired temperature. As such, it’s working harder, which means higher utility bills.

Dichlorodifluoromethane (R-12) was the most common blend used in automobiles in the U.S. until 1994, when most designs changed to R-134A due to the ozone-depleting potential of R-12. R-11 and R-12 are no longer manufactured in the U.S. for this type of application, so the only source for air-conditioning repair purposes is the cleaned and purified gas recovered from other air conditioner systems. Several non-ozone-depleting refrigerants have been developed as alternatives, including R-410A. It was first commercially used by Carrier Corp. under the brand name Puron.[citation needed]

Hi. I hope someone can help me. I have a has water heater amd it seems to only work when it wants to. Regardless of amount of use some days I have got water and some days it runs out of hot water immediately even if it hasn't been used all day. And some days it runs out half way through a shower. I have already turned the temperature almost all the way up and nothing is helping. Is there a way too fix this or is it time for a replacement?
All AC repairs were not created equal. While a new filter could cost as low as $20, a refrigerant leak repair can cost up to $1,600. Just like any aspect of the house, certain repairs will mostly depend on the damage. Clearly, the more serious issues will cost more. That not only means more time for the HVAC pro, but more complexity and materials as well. Sadly, neither come without a hefty markup.
A mini-split system typically supplies air conditioned and heated air to a single or a few rooms of a building.[38] Multi-zone systems are a common application of ductless systems and allow up to 8 rooms (zones) to be conditioned from a single outdoor unit. Multi-zone systems typically offer a variety of indoor unit styles including wall-mounted, ceiling-mounted, ceiling recessed, and horizontal ducted. Mini-split systems typically produce 9,000 to 36,000 Btu (9,500–38,000 kJ) per hour of cooling. Multi-zone systems provide extended cooling and heating capacity up to 60,000 Btu's.
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.
Packaged terminal air conditioner (PTAC) systems are also known as wall-split air conditioning systems.[36] They are ductless systems. PTACs, which are frequently used in hotels, have two separate units (terminal packages), the evaporative unit on the interior and the condensing unit on the exterior, with an opening passing through the wall and connecting them. This minimizes the interior system footprint and allows each room to be adjusted independently. PTAC systems may be adapted to provide heating in cold weather, either directly by using an electric strip, gas, or other heater, or by reversing the refrigerant flow to heat the interior and draw heat from the exterior air, converting the air conditioner into a heat pump. While room air conditioning provides maximum flexibility, when used to cool many rooms at a time it is generally more expensive than central air conditioning.
Inside the unit, the air passes over the evaporator coil first, and is cooled and dehumidified. The now dehumidified, cold air then passes over the condenser coil where it is warmed up again. Then the air is released back into the room. The unit produces warm, dehumidified air and can usually be placed freely in the environment (room) that is to be conditioned.
The condenser fan is another important HVAC element that must be maintained. Condenser fans that contain oil ports should be lubricated at least annually. The outside condenser should also be shielded from direct sunlight if possible. Keeping vegetation at least two feet away from outdoor HVAC units will also promote higher performance and potentially lower energy bills due to higher efficiency. The further away vegetation is, the better an HVAC unit will operate. 
During a seasonal tune-up, our technicians run diagnostics on every part of your system. We make sure the fans run smoothly, the thermostat is programed to your liking, and that all critical parts are not showing signs of wear. If a component needs replacing, we will replace it for you before it gives out. We’ll even replace the filter for you – one less hassle!
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.
