Denver HVAC Repair

You can keep your air conditioner running efficiently with some preventative care measures. Shut off the power to your AC before cleaning it or performing any of these tasks:  clean your filter at least twice a year; remove leaves and twigs from cages; clean the fins with a garden hose or special spray, then use a butter knife to straighten any that are crooked; keep your yard clean so the fins won't get blocked; cover the unit up for winter; and make sure it's level or you run the risk of damaging the inner workings of the unit.

A specialized air conditioner that is used only for dehumidifying is called a dehumidifier. It also uses a refrigeration cycle, but differs from a standard air conditioner in that both the evaporator and the condenser are placed in the same air path. A standard air conditioner transfers heat energy out of the room because its condenser coil releases heat outside. However, since all components of the dehumidifier are in the same room, no heat energy is removed. Instead, the electric power consumed by the dehumidifier remains in the room as heat, so the room is actually heated, just as by an electric heater that draws the same amount of power.

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.
"Friendly, professional, responded quickly to my problem. I have called many air conditioning companies about my problem including the maker of the unit and had come to the conclusion that I would not find someone to repair this unit. D's came in and within a short test found the problem and assured me of a fix. They made the fix within 2 days as they needed to get a part and they also checked to see what the cost would be of the fix by putting in the control boarrd from the maker which was very high to the extreme. I now have a unit working and am very pleased."
Designed to improve manufacturing process control in a printing plant, Carrier's invention controlled not only temperature but also humidity. Carrier used his knowledge of the heating of objects with steam and reversed the process. Instead of sending air through hot coils, he sent it through cold coils (filled with cold water). The air was cooled, and thereby the amount of moisture in the air could be controlled, which in turn made the humidity in the room controllable. The controlled temperature and humidity helped maintain consistent paper dimensions and ink alignment. Later, Carrier's technology was applied to increase productivity in the workplace, and The Carrier Air Conditioning Company of America was formed to meet rising demand. Over time, air conditioning came to be used to improve comfort in homes and automobiles as well. Residential sales expanded dramatically in the 1950s.[citation needed]
If your heating system is not running efficiently, it will not heat your home effectively. A good sign you have an inefficient heater is if you notice some rooms in your house aren’t heating to the temperature you set. Older systems could have difficulty heating your entire household, and you’ll know this if you notice some rooms are warmer than others.

Ductwork pinging or popping. If you hear a pinging or popping sound coming from metal ductwork, this may be caused by thermal expansion or by air blowing past a loose flap of metal. Track along the duct runs, listening for the sound. If you find it, make a small dent in the sheet metal to provide a more rigid surface that’s less likely to move as it heats and cools.


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).

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.
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]

Your HVAC professional can perform a yearly tune-up of your system for around $80-$100. This yearly maintenance can go far toward heading off major repairs to your system, and provide you with peace of mind and considerable savings in the long term. Additionally, regular servicing of your AC unit can help a home inspector to certify that your unit is working properly in the event you decide to sell your home.
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.
Ventilation is the process of changing or replacing air in any space to control temperature or remove any combination of moisture, odors, smoke, heat, dust, airborne bacteria, or carbon dioxide, and to replenish oxygen. Ventilation includes both the exchange of air with the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality in buildings. Methods for ventilating a building may be divided into mechanical/forced and natural types.[16]

Modern air conditioning systems are not designed to draw air into the room from the outside, they only recirculate the increasingly cool air on the inside. Because this inside air always has some amount of moisture suspended in it, the cooling portion of the process always causes ambient warm water vapor to condense on the cooling coils and to drip from them down onto a catch tray at the bottom of the unit from which it must then be routed outside, usually through a drain hole. As this moisture has no dissolved minerals in it, it will not cause mineral buildup on the coils. This will happen even if the ambient humidity level is low. If ice begins to form on the evaporative fins, it will reduce circulation efficiency and cause the development of more ice, etc. A clean and strong circulatory fan can help prevent this, as will raising the target cool temperature of the unit's thermostat to a point that the compressor is allowed to turn off occasionally. A failing thermistor may also cause this problem. Refrigerators without a defrost cycle may have this same issue. Dust can also cause the fins to begin blocking air flow with the same undesirable result: ice.
The condenser fan moves air across the coil to increase the transfer of heat. It is critical to the system. Obstructing the flow of air will not only reduce efficiency, but can lead to compressor failure. Keep debris and objects away from the coil and fan to allow maximum air flow. Some condenser fan motors have sealed bearings, others need lubrication. Damage to the fan can occur if removed improperly. Have a qualified serviceman handle the lubricating if needed.
   As for parts prices, we are a business and factor in profit and overhead into our pricing structure, and frequently research other companies to be sure we are competitive, which we are. Jody, you did not pay $400 for labor, you paid $489 for a flat rate repair which included, travel, labor, diagnostics, parts, tax, shipping, truck charge, fuel charge, overtime rate, profit and overhead. As for the time of the actual repair, if it had taken 2 or 3 hours the cost would have still been the same $489.        
Absolutely horrible service dont show or call within there appointment window, half to blow up the o...wners phone after there appointment window to get any answers why. And then it takes another 2 hours for there tech to get there after you were told it would be only an hour. Horrible customer service even though it was a Saturday and they made the appointment. But the tech was very professional. Never recommend them only had to use them cause of insurance See More
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!

Natural ventilation is a key factor in reducing the spread of airborne illnesses such as tuberculosis, the common cold, influenza and meningitis. Opening doors, windows, and using ceiling fans are all ways to maximize natural ventilation and reduce the risk of airborne contagion. Natural ventilation requires little maintenance and is inexpensive.[19]

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.

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.

Replacing your old heating and cooling equipment with new, energy-efficient models is a great start. But to make sure that you get the best performance, the new equipment must be properly installed. In fact, improper installation can reduce system efficiency by up to 30 percent - costing you more on your utility bills and possibly shortening the equipment's life. Learn more.
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.

Energy efficiency can be improved even more in central heating systems by introducing zoned heating. This allows a more granular application of heat, similar to non-central heating systems. Zones are controlled by multiple thermostats. In water heating systems the thermostats control zone valves, and in forced air systems they control zone dampers inside the vents which selectively block the flow of air. In this case, the control system is very critical to maintaining a proper temperature.

With the right equipment and regular maintenance, your heating and cooling systems can pay you back. Our NATE-certified technicians are trained to maintain and repair central air conditioners and heat pumps from Carrier and all other brands. If you are experiencing problems with your furnace or AC system, we’ll make sure that your system is working properly, and we won’t leave until the job is complete and your home is comfortable. In this busy world, we understand the importance of prompt appointment scheduling and reliable service. We even offer 24-hour emergency service and after-hours air conditioner repairs that fit your busy schedule.
In 2006, a new HVAC rule went into affect for residential air conditioners, requiring all to have a Seasonal Energy Efficiency Ratio (SEER) of 13 or higher. As you might expect, the more efficient the unit is (or newer), the lower your average AC repair cost will be. Keep in mind, if for some reason your high-efficient repair bill is high, you’re still saving on energy costs every month through your electric and gas bills. 
Repairs—If something appears to be not working right with your heating and cooling, a professional will examine the whole health of your system. It’s easy to hop on the internet and research information to find our own conclusions, but there could be an additional component or reason why your system isn’t working properly that isn’t clear or recognizable. Consider our own health concerns—you might check out your symptoms online to try and draw your conclusions, but it’s always best to make an appointment with a doctor to receive an expert opinion.
