Denver HVAC Repair

My A/C went out on a Friday and I found this company in the phone book on Saturday morning. They came out just a few hours later and it was decided that I needed a new system. The pricing was good as well as the customer service. They brought me a temporary portable air conditioner for Saturday night and they replaced my system on Sunday. This company has the best customer service of any business that I have dealt with. I would highly recommend this company to anyone and have. Great Company!!!!!

Shortly thereafter, the first private home to have air conditioning was built in Minneapolis in 1914, owned by Charles Gates.[11] Realizing that air conditioning would one day be a standard feature of private homes, particularly in regions with warmer climate, David St. Pierre DuBose (1898-1994) designed a network of ductwork and vents for his home Meadowmont, all disguised behind intricate and attractive Georgian-style open moldings.[when?] This building is believed to be one of the first private homes in the United States equipped for central air conditioning.[12]


Every Trane system is tested in some of the most extreme conditions found in nature to ensure they’re truly unstoppable – like freezing conditions in our System Extreme Environmental Test (SEET) lab. That’s where engineers put units through five years of wear and tear in just a few months, to get a product you can count on to run through anything. We never settle, so they never stop.

Air conditioning makes deep plan buildings feasible, for otherwise they would have to be built narrower or with light wells so that inner spaces received sufficient outdoor air via natural ventilation. Air conditioning also allows buildings to be taller, since wind speed increases significantly with altitude making natural ventilation impractical for very tall buildings.[citation needed] Comfort applications are quite different for various building types and may be categorized as:
I could not have been more pleased with the responsiveness, considerate employees, workmanship, and follow up. We used three divisions of Bill Howe when we had a flood due to a water heater/T&P gauge, Plumbing, Remediation and Reconstruction. It was timely, reasonably priced and finished with attention to detail. Ashley in the office was always polite and responsive and we could not have been happier under the circumstances.
The Refrigeration Loop is a closed system and refrigerant should never have to be added to the unit unless there is a leak. Most residential units use R-22/R410A refrigerant. Prices of R-22/R410A are rising every year as we get closer to the date when refrigerant manufacturers will no longer be able to make R-22/R410A. Phase-out of R-22, an HCFC, begins in 2010 and expected to be complete by 2020.). Furthermore, make sure you ask what the service company charges for R-22 when you are calling an HVAC contractor.
One of the easiest maintenance tasks consumers can do themselves is maintaining the filters. Air filters should be inspected and cleaned once a month. This allows for regular monitoring to eventually determine when the filter needs to be replaced. Most filters can be changed every three months if no other problems exist. Maintaining clean and regularly changed filters will not only produce better air quality, but appliances will function more efficiently, which can save on heating and cooling costs.

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.
Circulating refrigerant vapor enters the compressor, where its pressure and temperature are increased. The hot, compressed refrigerant vapor is now at a temperature and pressure at which it can be condensed and is routed through a condenser. Here it is cooled by air flowing across the condenser coils and condensed into a liquid. Thus, the circulating refrigerant removes heat from the system and the heat is carried away by the air. The removal of this heat can be greatly augmented by pouring water over the condenser coils, making it much cooler when it hits the expansion valve.
In the UK, the Ozone Regulations[62] came into force in 2000 and banned the use of ozone depleting HCFC refrigerants such as R22 in new systems. The Regulation banned the use of R22 as a "top-up" fluid for maintenance between 2010 (for virgin fluid) and 2015 (for recycled fluid). This means that equipment that uses R22 can still operate, as long as it does not leak. Although R22 is now banned, units that use the refrigerant can still be serviced and maintained.

The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system's efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner's energy consumption by 5% to 15%.

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]
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.
If your unit needs more than two pounds or charged more than once a year it is recommended you have a refrigerant leak check done to your system. You most likely have a serious refrigerant leak and it needs to be repaired. Leaking units do not operate efficiently; take their toll on the environment, and can cause serious HVAC mechanical problems in the future. Lastly, a good HVAC service tech will attempt to find the refrigerant leak within the hour’s air conditioning service you are paying for in addition to the refrigerant charge.

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!
An important component of natural ventilation is air change rate or air changes per hour: the hourly rate of ventilation divided by the volume of the space. For example, six air changes per hour means an amount of new air, equal to the volume of the space, is added every ten minutes. For human comfort, a minimum of four air changes per hour is typical, though warehouses might have only two. Too high of an air change rate may be uncomfortable, akin to a wind tunnel which have thousands of changes per hour. The highest air change rates are for crowded spaces, bars, night clubs, commercial kitchens at around 30 to 50 air changes per hour.[17]

First, it is wise to stick with a company that specializes in HVAC services. While many general handyman companies may do some things with AC units, a company that specializes in air conditioning and heating is always a better option. Because air conditioning repairs can be quite costly, depending on the particular problem, it is best to work with highly trained HVAC professionals to ensure quality work.

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.
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.

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.

Per hour service charges are not the only way companies charge their customers. There are also service companies that flat rate their services. Either way, you pay, you want the service and troubleshooting done in a quick and efficient manner with a guarantee. Do your research before selecting a company to provide reliable, honest service to your home. If you know what the problem is then the company can likely give you an estimate over the phone. Some will while some do not. Why? Because they likely want to verify the problem to make sure it is a correct assessment. It can be a complex issue and what you think it is it may not be the problem. So you can expect to pay for a service call and troubleshooting charge. Most HVAC service companies do not give free estimates on repairs.

The belt should slip right into place. If it seems to be too tight or difficult to set in place, it may be necessary to adjust the motor mount to provide more slack. Then you can re-tighten the tension once the belt is in place. Check the manufacturer’s specifications for proper tension—in most cases, the belt should deflect about an inch when you press down on it.

In the most general sense, air conditioning can refer to any form of technology that modifies the condition of air (heating, (de-)humidification, cooling, cleaning, ventilation, or air movement). In common usage, though, "air conditioning" refers to systems which cool air. In construction, a complete system of heating, ventilation, and air conditioning is referred to as HVAC.[3]
In 1820, English scientist and inventor Michael Faraday discovered that compressing and liquefying ammonia could chill air when the liquefied ammonia was allowed to evaporate. In 1842, Florida physician John Gorrie used compressor technology to create ice, which he used to cool air for his patients in his hospital in Apalachicola, Florida. He hoped to eventually use his ice-making machine to regulate the temperature of buildings. He even envisioned centralized air conditioning that could cool entire cities. Though his prototype leaked and performed irregularly, Gorrie was granted a patent in 1851 for his ice-making machine. Though his process improved the artificial production of ice, his hopes for its success vanished soon afterwards when his chief financial backer died and Gorrie did not get the money he needed to develop the machine. According to his biographer, Vivian M. Sherlock, he blamed the "Ice King", Frederic Tudor, for his failure, suspecting that Tudor had launched a smear campaign against his invention. Dr. Gorrie died impoverished in 1855, and the dream of commonplace air conditioning went away for 50 years.[citation needed]

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.


Are you considering whether you need to replace your home’s central heating, ventilation, and air conditioning unit—commonly known as your HVAC system? As a general rule, if your existing HVAC system is more than 15 years old, it’s only a matter of time before it starts to cost more to maintain than it would to replace it with a new system. In addition to higher energy bills brought on by a system that can no longer function at peak efficiency, repair costs will also start to add up as parts are replaced and the ventilation system undergoes major overhauls.

There is a premium for most any service company to come out afterhours or weekends, and being we are one of the very few companies to offer this service, a higher labor rate is understandable, after all, we have to pay our service persons an overtime rate for such calls.          
My mom just received service from this company. She paid $609 to have her frion replaced. After two uses the AC stops working. A young rep comes out to the house again and notifies her that her entire AC unit and furnace need to be replace for just shy of ten grand, though when her frion was refilled she was told that her system should last another five years. When they came back to tell her how her entire system needed to be replaced, they were generous enough to offer her a $300 credit on the nearly $10,000 estimate of replacing the entire system that was working fine until they touched it. My best assumption would be that there is a mishap with the system is due to their negligence. Id suggest using another company other than these scam artists. Update: Alberto soon messages me about the negative review telling me how I am wrong and that they are the best mechanical contractors in the Bay Area. Literally told me that I was wrong. Not sure how you can get much more arrogant than that. Stay clear of these clowns.
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.

HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels and senior living facilities, medium to large industrial and office buildings such as skyscrapers and hospitals, on ships and submarines, and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.
Evaporative coolers tend to feel as if they are not working during times of high humidity, when there is not much dry air with which the coolers can work to make the air as cool as possible for dwelling occupants. Unlike other types of air conditioners, evaporative coolers rely on the outside air to be channeled through cooler pads that cool the air before it reaches the inside of a house through its air duct system; this cooled outside air must be allowed to push the warmer air within the house out through an exhaust opening such as an open door or window.[28] These coolers cost less and are mechanically simple to understand and maintain.

Heaters exist for various types of fuel, including solid fuels, liquids, and gases. Another type of heat source is electricity, normally heating ribbons composed of high resistance wire (see Nichrome). This principle is also used for baseboard heaters and portable heaters. Electrical heaters are often used as backup or supplemental heat for heat pump systems.

Wow! These guys rock! I had issues with our fireplace for a while and the last company who "fixed" the issue basically charged me a lot of money and literally left me standing in the cold. Next they said it would cost me over $700 to fix the whole thing and they never came back. Finally I was able to find some good guys to fix the issue. Tony and Paul from HVAC were not only really friendly, they diagnosed the issue really fast and fixed it the same day. And it was 7 times less than what the other company asked for!!! Next time I know who to call! 5 Stars!

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.
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.
