Air Conditioning Repair Denver

AC Repair and Service in Denver

When an air conditioner is not operating properly it will have to be diagnosed by one of our service technicians to determine the problem, in some cases the problem is minor, others require parts, refrigerant and sometimes you may need a new air conditioner repair, replacement and installation.

Denver’s hot spells make home air conditioning a highly valued amenity. If your household includes infants, elderly, and seriously ill individuals, air conditioning is often a necessity. Don’t wait for a breakdown. Our AC repair technicians in Denver will perform the manufacturer’s recommended routine and preventative maintenance on your air conditioner. We recommend that your air conditioner be inspected each year, usually a month or two before you will be using it. You will have peace of mind that your air conditioner will perform at maximum efficiency throughout the summer season in Denver, CO.

Even so, you should be alert for problems that can become major if not attended to:

  • Strange smells coming from the air conditioning unit or system
  • Filters that are dirty or clogged and need cleaning
  • Unusual noises coming from the unit
  • Insufficient cool air delivered by the unit
  • Oil leaks from the unit, usually a thick blackish-brown liquid

What to Check if Your AC Is Not Working Properly

If your AC is not working at all, first check that it is getting power. A tripped fuse or switch is easy to repair by opening your electrical panel and finding the AC switch. It will be 240 volts. If it is off, simply switch it back on. If the switch does not trip again, you do not have a problem. Next check the thermostat. It should be set to “cool” and the temperature should be set at 3 degrees lower than the reported air temperature. Make sure the thermostat batteries do not need replacing. Check the switch in the furnace or air handler and in the outdoor compressor. In a metal box mounted by the compressor, there is usually a disconnect switch. Make sure that it is on.

If your AC is working, but not cooling the house as well as it did previously, do the following:

  • Check windows and doors. According to the U.S. Department of Energy, one of the top air conditioning problems is open windows and outside doors. Even a crack in door and window openings can make a difference in your air conditioner’s capacity to cool your house. Also, if you are experiencing an unusual amount of door traffic, wait until the door is closed for an hour before deciding if you have a problem.
  • Remove brush and debris from an outside unit and surrounding area as this will interfere with air intake and can slow your system.
  • Check the condenser coil and the surrounding area of an outdoor unit. Dirty coils interfere with the transfer of heat and make your unit work harder and wear out faster.
  • Install a programmable thermostat, which saves energy and is more accurate.
  • Inspect filters and replace dirty ones.
  • Check ducts for rips and tears and have them repaired.
  • Check drainage lines. Water leaks can damage your home as well as your air conditioning system.
  • Check the refrigerant level. If there is ice buildup on the copper lines or evaporator coil, you probably have a leak. A qualified HVAC and home services expert needs to look at it. Some leaks can be repaired and more refrigerant added. However, if there are multiple leaks a new unit may be needed.
