Denver HVAC Repair

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.

Multiple inventions within this time frame preceded the beginnings of first comfort air conditioning system, which was designed in 1902 by Alfred Wolff (Cooper, 2003) for the New York Stock Exchange, while Willis Carrier equipped the Sacketts-Wilhems Printing Company with the process AC unit the same year. Coyne College was the first school to offer HVAC training in 1899.[12]
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.
Central air conditioners are more efficient than room air conditioners. In addition, they are out of the way, quiet, and convenient to operate. To save energy and money, you should try to buy an energy-efficient air conditioner and reduce your central air conditioner’s energy use. In an average air-conditioned home, air conditioning consumes more than 2,000 kilowatt-hours of electricity per year, causing power plants to emit about 3,500 pounds of carbon dioxide and 31 pounds of sulfur dioxide.

If the air conditioner on your thermostat set low, and you aren't feeling cool air, it could be that debris is blocking the condenser. Check on your system outside and remove any tree branches or leaves from around it. Debris can easily obstruct air flow, so make sure the area around your air conditioning unit is clean and trimmed back. Make sure your filter is clean. A buildup of dirt and dust can cause poor air circulation.

Within the construction sector, it is the job of the building services engineer to design and oversee the installation and maintenance of the essential services such as gas, electricity, water, heating and lighting, as well as many others. These all help to make buildings comfortable and healthy places to live and work in. Building Services is part of a sector that has over 51,000 businesses and employs represents 2%-3% of the GDP.
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.

1) Your air conditioner is not working at all. Before calling in a professional to address this issue, you may want to check a few things yourself. Check to see if your thermostat is set to “cool”. Confirm that your designated cooling temperature is less than the temperature of the room or home. If everything is set correctly, check the electrical panel to be sure you do not have a tripped breaker. If these things all check out and your air condition unit is still not working, it is time to call in a professional.

The 2nd-century Chinese mechanical engineer and inventor Ding Huan of the Han Dynasty invented a rotary fan for air conditioning, with seven wheels 3 m (10 ft) in diameter and manually powered by prisoners of the time.[6] In 747, Emperor Xuanzong (r. 712–762) of the Tang Dynasty (618–907) had the Cool Hall (Liang Dian 涼殿) built in the imperial palace, which the Tang Yulin describes as having water-powered fan wheels for air conditioning as well as rising jet streams of water from fountains. During the subsequent Song Dynasty (960–1279), written sources mentioned the air conditioning rotary fan as even more widely used.[7]

We moved into a new home and had issues with the heating ducts in one of the rooms. We called HVAC based on other yelp reviews. Overall, everyone we dealt with were friendly, professional and knowledgeable: From the people on the phone managing the schedule to the those performing the work in our house. The day before the scheduled work we asked if additional work could be done (clothes dryer duct cleaning), which they were able to accommodate. The people working at the house were on time, very polite, took great care to keep the house clean during the entire job and explained everything when they were finished. I will certainly use HVAC again.
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
CIBSE publishes several guides to HVAC design relevant to the UK market, and also the Republic of Ireland, Australia, New Zealand and Hong Kong. These guides include various recommended design criteria and standards, some of which are cited within the UK building regulations, and therefore form a legislative requirement for major building services works. The main guides are:
We offer maintenance and tune-ups for all brands of central heating and air conditioning equipment. Systems serviced include central air conditioners, furnaces, heat pumps, and air quality systems such as whole-home humidifiers, dehumidifiers, and air cleaners.

We’ve found that many homes and businesses in Atlanta face significant indoor air quality issues as a result of the seasonal high humidity in our area, which creates conditions ripe for mold and mildew growth in both old and new HVAC systems. Our HVAC technicians can help you determine which strategies will work best for neutralizing airborne particulates in your home, which often involves a combination of filtration methods and ultraviolet light technology that together can help keep your system perpetually free of contaminants. We can also install whole-house dehumidifiers and humidifiers, which can make a huge difference in the amount of work your HVAC unit will have to do to be effective.
In addition to the information below, see these two articles for the general care and maintenance of your air conditioner: Preparing Your Air Conditioner for Summer and How to Replace Furnace & AC Filters. Most noteworthy, you should replace the filters at least twice a year, before the heating and cooling seasons. For information on furnace problems, please see Furnace Not Working.

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.
5) Adjust your thermostat. If you are away for large stretches of time every day, adjust your thermostat to a higher temperature for the time you are away. This will lessen the amount of time your unit has to work each day, and will lengthen its life cycle. An additional benefit will be a lower utility bill each month. Some newer thermostats allow you to pre-program your thermostat to match your schedule so that your home will still be cool when you arrive. Optimizing your system’s usage will maximize its life in the long term.
Some systems include an "economizer mode", which is sometimes called a "free-cooling mode". When economizing, the control system will open (fully or partially) the outside air damper and close (fully or partially) the return air damper. This will cause fresh, outside air to be supplied to the system. When the outside air is cooler than the demanded cool air, this will allow the demand to be met without using the mechanical supply of cooling (typically chilled water or a direct expansion "DX" unit), thus saving energy. The control system can compare the temperature of the outside air vs. return air, or it can compare the enthalpy of the air, as is frequently done in climates where humidity is more of an issue. In both cases, the outside air must be less energetic than the return air for the system to enter the economizer mode.
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.
When your heating or cooling system finally breaks, it’s not usually during convenient office hours or in mild weather. Your HVAC unit has to work harder during extreme conditions like a sweltering summer day or freezing winter night, so it is much more likely to fail during those times. R.S. Andrews has our customers’ safety and comfort as our priority, so we offer service 24 hours a day for emergencies. No matter when your equipment fails, you can count on us to repair it quickly and efficiently!
Your HVAC professional can also help you verify that your system is properly matched by providing you with an AHRI Certificate of Certified Product Performance upon request. The certificate verifies that the outdoor unit (condenser) and the indoor unit (evaporator) combination has been certified as a matched system by the Air Conditioning, Heating and Refrigeration Institute (AHRI). For higher efficiency systems, this certification may help you obtain a rebate from your utility or local municipality, if you have to replace your unit in whole or in part. Not all areas offer a rebate, but your technician will likely be able to provide information about the certification process. Fees for performing this certification vary, but generally are relatively inexpensive.

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.


HVAC professionals attend to a home's thermal needs as well as air quality. Because of the technical aspects of HVAC work, find out the scope of work your professional can perform. You may only need your heating unit serviced however, if this professional also specializes in energy efficiency, mold assessment, or offer ways for you to save on energy costs, you may want to hire them for future projects. Because some equipment is gas-powered, your professional should be able to answer questions about installing gas lines and permitting.
We will get into specifics later, but there are plenty of recommended maintenance items all homeowners should strongly consider if you want you to extend the lifespan of your AC unit. Furthermore, regular maintenance prevents certain repairs less organized homeowners see every few years. Some easy and highly recommended AC unit maintenance tasks include:
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]
Absorption heat pumps are a kind of air-source heat pump, but they do not depend on electricity to power them. Instead, gas, solar power, or heated water is used as a main power source. An absorption pump dissolves ammonia gas in water, which gives off heat. Next, the water and ammonia mixture is depressurized to induce boiling, and the ammonia is boiled off, which absorbs heat from the outdoor air.[citation needed]

In 1995, Germany made CFC refrigerators illegal.[22] DuPont and other companies blocked the refrigerant in the U.S. with the U.S. EPA, disparaging the approach as "that German technology".[21][23] Nevertheless, in 2004, Greenpeace worked with multinational corporations like Coca-Cola and Unilever, and later Pepsico and others, to create a corporate coalition called Refrigerants Naturally!.[22][24] Then, four years later, Ben & Jerry's of Unilever and General Electric began to take steps to support production and use in the U.S.[25] In 2011 the EPA decided in favor of the ozone- and climate-safe refrigerant for U.S. manufacture.[17][26][27]

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.
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.

Outside of your home is an outdoor unit, which is called a condenser. Inside the condenser is a compressor, a condenser coil, and a large fan. The compressor pumps cool refrigerant to an evaporator coil located either in the air handler or just outside the furnace. The evaporator coil gets really cold so that when the blower or furnace pushes warm air past it, the air is cooled. This cool air is then distributed throughout your home through a series of air ducts. Heat is absorbed by the evaporator coil, which warms the refrigerant moving through the coils. This warm refrigerant is then pumped back outside to the condenser coil, where a giant fan cools it off allowing the warm air to escape. This cycle is repeated until your thermostat detects that your home has reached the temperature you set it to.
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.
