While some HVAC problems are just a matter of cleaning filters and coils, something that you can do, many of the common HVAC issues will grow into much bigger things if not handled early. Most of these can be evaded with regular preventive maintenance work. It’s smart to have your unit examined every year to stop outages.

Maintenance
Routinely scheduled maintenance by a licensed Rochester heating and cooling contractor is imperative to keep your unit in the right working order.

Why not safeguard that investment? If you forget to get regular maintenance, you will probably experience rising energy costs, unpredicted breakdowns, frustration, and bad performance.

Dirty Filters
Swapping out your filter frequently is one of the most crucial things you can do to prolong the efficiency and life of your system. If your filter is dirty, it will limit airflow making your unit work harder to move the air through your house. This puts a needless strain on your unit’s blower, resulting in comfort problems. Also, a dirty filter causes the unit to shut off and overheat.

Ignition and Pilot Issues
Pilot issues can come from numerous reasons. A dirty burner, flames sensor, or pilot can cause short cycling or delayed ignition of the burners. Also, it can be due to a gas supply issue or wear and tear of an ignition component that should be replaced like the thermocouple or hot surface ignitor. It is best to have these issues handled by a trained HVAC repair technician since this deals with hazardous elements like high voltage and natural gas.

Weird Furnace Noises
There are normal furnace noises, while others may be an indication of a mechanical issue. A squealing or whining motor can be a sign that the bearings in a blower motor or inducer motor are breaking down. Replacing the motor may be necessary to stop a furnace failure. Some noises may be due to dirty burners or airflow problems. It’s best not to neglect these warnings as they may be telling you of a dangerous operating condition.
