HVAC Preventative Maintenance Services

The best way to avoid needing emergency HVAC repair is thorough HVAC preventative maintenance.

During the spring, before the heat waves of summer begin, and in the fall, before the frigid winter temps arrive, you should have your HVAC system checked by a professional technician from Holbrook Heating & Air Conditioning to make sure it is functioning properly and efficiently. Not only does this help avoid emergency situations, but it can also help lower your heating and cooling costs.

HVAC Preventative Maintenance from Homeowners

There are a few things you can do on your own for HVAC preventative maintenance:

Air filters should be replaced approximately every 90 days, but check them each month to be sure. If you have pets in your home, you’ll likely need to change them more often. A good rule of thumb is that if you hold the filter up to a light and you can’t see through it, then it’s time to replace.

Make sure there are no obstructions within 2 feet of your outdoor central air conditioning system. Also be sure to keep the space clear of leaves, pollen, twigs, and grass clippings from the lawnmower.

Each month, check the insulation on refrigerant lines. If they are missing or damaged, they should be replaced.

Every year, make sure that your outdoor AC system is on firm, level ground.

Once per year, pour a mixture of water and bleach into the condensate drain to help prevent the buildup of mold and algae which can lead to a clog.

During summer, turn off the water supply to the furnace humidifier. When fall arrives, it’s time to replace the humidifier wick filter and set the humidistat to 35-40% relative humidity. You can also turn the water supply back on.

Always keep at least 80% of your home’s registers open to avoid choking up your HVAC system.

HVAC Preventative Maintenance from Holbrook Heating & Air Conditioning

Twice a year you should make an appointment to have a Holbrook Heating & Air Conditioning professional technician visit your home to inspect your HVAC system. Here are a few things we look out for on one of those visits:
  • Check for dirt, leaves and other debris inside the cabinet and clean the area.
  • Audit the base pan for restricted drain openings and remove obstructions if needed.
  • Check out the coil and cabinet and clean as needed.
  • Go through the control box, any controls or accessories, the wiring, and connections checking for wear or damage.
  • Inspect the compressor and tubing for damage.
  • Observe refrigerant levels and adjust as necessary.
  • Review the fan motor and blades for significant wear or damage. For older models, we may need to lubricate as well.
