Tips to Keep Your Heating System Running at its Best

There are some simple things you can do to make sure your home heating system operates at peak performance.

“High/Low” return air grilles need to be changed seasonally for the maximum efficiency of your heating and cooling system. During the heating season, open the bottom grille and close the top grille, this will draw the cool air off the floor. During the cooling season close the bottom grille and open the top grille, this will draw warm air from the ceiling.

To ensure proper air flows through your system, keep both registers and grilles free from obstructions such as furniture and drapes.

Your heating and cooling system will work most efficiently if you set your thermostat at a comfortable temperature (68-72 for heating and 74-78 for cooling) and leave it there rather than continually adjusting it. Programmable thermostats can provide a significant energy savings. The thermostat can be set at a reduced setting overnight or during the day while you’re at work, and be set to raise the temperature to your normal setting before you wake up or return from work. These thermostats are available in a 5 day/2 day format to allow you to program separate settings for the weekend. Call Groff’s for more information and prices for adding a programmable thermostat to your heating and cooling system.

If your heat pump or air conditioner indoor or outdoor coil is frozen, it is usually due to either a dirty air filter or the unit being low in refrigerant. Check your unit’s filter. Clean or replace as needed. If this doesn’t solve the problem, call Groff’s Home Comfort Team to schedule a service call. Our certified technicians will check the refrigerant pressure and refill as needed. We will also determine the source of any refrigerant leaks and make necessary repairs.

In the winter it’s important to keep your outdoor heat pump clear of shrubbery, leaves, snow and ice. When it’s cold and damp, this outdoor unit will accumulate frost and ice. When this happens the unit goes into the defrost cycle, which causes the fan to shut off and the outdoor coils to heat up to melt the frost and ice. The “smoke” you may see coming from the unit is actually steam and is not cause for alarm.

Always make sure the furnace’s combustion air inlet and exhaust pipe (PVC elbow) are not obstructed by shrubbery, leaves, snow or ice. A clogged exhaust will cause the furnace to lock out and shut down. This situation will require a service call to correct.

If water appears to be leaking from the inside of your furnace or air handler, you probably have a clogged condensate drain. If you don’t keep your filter clean, dirt can collect on your coil and fall off into the drain pan, causing the drain to clog.

Contact Groff’s Home Comfort Team to schedule a service call to correct the problem. Regular servicing of your heating and cooling system will usually prevent this problem.
