Maintenance Tips
Keeping your heating and cooling systems in good working order
means your utility bills will be lower, your home will be more comfortable,
and you’ll need to call for repairs less often.
Maintenance Scheduling
Schedule a maintenance service call before the heating season starts. If there are any
problems with your system, it’s better to find out before it’s freezing outside! Do the same
for your cooling system before sweltering season begins.

HIGH EFFICIENCY FURNACE AND AIR CONDITIONER  (95% EFFICIENCY)
If you have a furnace that is 10 years old or older, it’s probably within the 60 to 70%
efficiency range, which means you
waste up to 40 cents out of every dollar on fuel.

Filters
Replace your heating and cooling air filters every month that they’re in use. Operating your
system with old, dirty filters means energy is wasted and your system may even be
damaged. While you’re at it, check and clean the filters in your home’s air cleaners and
humidifiers.

System Checks
If you have a forced air heating system check your furnace’s blower compartment and
blower coils. Vacuum them if you see dirt and dust there. You should also check fan belt
tension, and lubricate fan and motor bearings.

If you have a steam system, check the shut-off valve for leaks.

Bleed hot water system radiators at least once a year.

Don’t keep clutter near your furnace. It’s a fire hazard, and may keep your system from
operating efficiently.

To make sure you’re getting the most out of your heating system, keep the heating
registers and vents throughout the house free of dust, dirt, and pet hair by vacuuming them
at least once a year.

Listen for odd sounds when your heating or cooling system kicks in. If you hear anything
unusual, get in touch with your service professional so you can head off problems before
they become serious.

In winter months, set your ceiling fan at its slowest speed and reverse it in order to gently
push warm air down from the ceiling without generating a breeze.

Safety Tips

During storms, make sure you turn your air conditioner off. A lightening power surge or if
the power is going off and on can ruin your air conditioning systems.  

When turning your air conditioner off, try to wait 3 to 5 minutes to allow the refrigerant
pressure to equalize before turning your air conditioner back on.  It gets very hard on your
compressor, when it tries to start under high pressure, if you do not wait for your system
pressures to equalize.

If you have a fossil fuel (Natural Gas, Liquid Propane, Oil, Coal, Wood burning) furnace
purchase a good Carbon Monoxide detector.
