Your air conditioning and heating systems are complex machines that need careful maintenance to keep them running efficiently. When one part of the system is damaged, it can put strain on the other HVAC parts, making them more likely to break down. To keep this from happening and to minimize the extent and cost of repairs, here's what you should know about heating and cooling maintenance.

HVAC Parts Maintenance FAQ

How often should I replace my air filter?

This is the most frequent maintenance task you should perform at home. The rule of thumb is that your filter should be replaced every one to three months. The exact timing depends on the type of filter you choose and the factors affecting your home. For instance, if you have a pet or live in an especially dusty environment, your air conditioner and furnace filters will need to be changed more often. You can tell it's time to change the filter when you hold it up to a light and can’t see any light through it.

How should I choose an air filter?

There are several filter options available at your local AC parts supplier, including fiberglass, pleated, electrostatic, and HEPA options. Fiberglass filters are the least expensive option, while HEPA filters are the most efficient ones and produce the best air quality. If anyone in your home has allergies, HEPA filters are recommended.

What should I set my humidistat to?

For the best air quality and a minimized chance of mold growth, your home's humidity should stay at about 40-50%. Any less, and you'll experience throat and skin irritation due to dryness. Any more, and you'll start to see mold growth on your home's surfaces.

How can I tell when my HVAC parts need repairs?

The surest sign of an HVAC problem is that the system isn't cooling or heating your home as intended. Other issues include unusual or loud noises, frozen or dripping units, unpleasant odors including mold smells, or a unit that is constantly running or turns on and off frequently.
