HVAC Installation, Repair, Maintenance Service


Cool Masters, Inc. services and repairs HVAC systems. Our mission is to assure your comfort while saving you money. We strive to provide prompt, efficient repair and outstanding customer service for your home or office HVAC system.

Your HVAC system makes up a substantial part of your home’s energy budget, so whether you need a new or are replacing an old one, installation is important. If it's not done correctly, you can face unwanted repairs and reduce the functioning life expectancy of the system. Cool Masters' skilled technicians have an outstanding record of proper air conditioning installations, heating installations and HVAC replacements.

Common problems


  • Cooling or Heating Issues - If the cooling system loses refrigerant, the equipment won't cool effectively. Insufficient refrigerant is one of the most common HVAC problems.
  • Issues with Efficiency - Systems can lose efficiency and increase your heating or cooling expenses because the system has to work harder and run more often. If your energy bills go up, call us to have your system checked.
  • Reduction in Air Quality - The air filters in your HVAC equipment work to remove particulates of dust, pollen, and other materials from indoor air. If air quality seems to be deteriorating, the filters may need changed.
  • Unusual Sounds - Strange or unusually loud noises could be a sign of trouble. Squealing or screeching noises may mean a fan or other moving part needs lubrication or should be changed. If your gas furnace develops popping or banging sounds, have it professionally checked as soon as possible.
  • Unresponsiveness - If your HVAC system won't work at all, the problem may be the thermostat. Replacing the batteries may be all you have to do to fix the problem, but if that doesn't work, you may have to replace the thermostat.

A tripped circuit breaker is another common cause of a non-functioning system. An occasional breaker trip isn't cause for alarm. If it happens frequently, however, it could indicate a potentially serious problem that should be checked by a professional.

Our certified technicians are always happy to answer any questions you may have.
