Trusted home air conditioning repair service.

• Check to see the output and return registers are open and free from obstacles like furniture.
• Make sure the emergency switch is in the “on” position.
• Check to see if any circuit breakers are off or have tripped.
• Make sure the doors to the filter or other parts of the heating system are fully closed.
• Water heating systems do not have or need filters.
• Make sure your thermostat is set to the heating mode in the winter and cooling mode in the summer.
• Check the batteries in your thermostat for corrosion in the battery compartment.
• Soot is a sign of serious problems. You should schedule a service call.

NOTE: Be patient during the summer months when it is very hot outside. You may be encountering a practical limit of cooling to about 20 degrees below the outside air temperature. Remember, if it is 95 degrees outside, the house may only be able to be cooled to 75 degrees. This may be a limitation of the air conditioning system and not necessarily a problem.

As soon as the outside temperature is over 65 degrees, test your AC system.

1. Turn the emergency switch to “on.”
2. Switch the thermostat to “cool.”
3. Set the temperature five degrees lower than the current room temperature. You should feel cool air coming from the registers in about five minutes.

• Make sure the caulking around your windows and doors is intact. A well-insulated home keeps the cooled air out and the heated air in.
• Use a programmable or smart thermostat to regulate the temperature of your home when you are away.
• Replace or clean your filters on a regular basis. A fresh filter helps keep the coil and heat exchanger clean, which increases energy efficiency, helping minimize the risk of breakdowns and helping extend the life of your heating and cooling system.
• In the cooler months, open your drapes and blinds on sunny days. Passive heat from sun, through a thermal window can make a room more comfortable.

During the summer, hot and hazy air can increase the amount of humidity inside your home. To help dehumidify your home, make sure it is properly ventilated and your AC system is sized correctly. Removing unwanted moisture from your home is a primary function of your home’s air conditioning system. However, sometimes your AC equipment alone may not be enough to remove the excess moisture that comes into your home. You may want to consider purchasing a dehumidifier.

The levels of relative humidity in the air can affect your home comfort, as well as the proper functioning of your heating and cooling system. The right level of moisture indoors will help your heating and cooling system work more efficiently. The addition of moisture (humidification) may be required during the winter season and the removal of moisture (dehumidification) may be required during the summer months.
