Here are some of the most frequent issues homeowners face:

Dirty or Clogged Filters:

Inadequate Heating:

If your heater isn’t warming your home evenly, it could be due to issues with the ductwork, a failing heating element, or an undersized system.

HVAC Maintenance Tips for Homeowners

Scheduling regular maintenance is the key to keeping your HVAC system running efficiently and preventing unexpected breakdowns. While some issues require professional assistance, there are simple tasks homeowners can handle to maintain their systems before calling in the experts.

Air Conditioning Maintenance

Check and Replace Filters:

Dirty filters can restrict airflow and reduce cooling efficiency. Check your filters every month and replace them every 1-3 months, especially during peak cooling season.

Clean Around the Outdoor Unit:

Remove leaves, dirt, and debris from around your outdoor condenser unit to improve airflow and prevent overheating.

Inspect and Clean Vents:

Make sure air vents are not blocked by furniture or curtains, and vacuum them regularly to remove dust and dirt.

Adjust Your Thermostat:

Use a programmable thermostat to optimize cooling schedules, reducing strain on your system during non-peak hours.

Check the Condensate Drain:

Ensure the drain line is clear of clogs to prevent water damage and maintain system efficiency.

Heating Maintenance

Replace Filters Regularly:

Like your air conditioner, your heater relies on clean filters. Replace them to maintain airflow and efficiency.

Inspect the Pilot Light or Ignition System:

If you use a gas heater, check the pilot light. A yellow or flickering flame may indicate a problem that needs attention.

Test the Thermostat:

Set your thermostat to heating mode and check if your system responds properly. Replace batteries if needed.

Check and Clean Registers:

Remove dust and debris from your heating registers to allow warm air to circulate freely.

Clear Around the Heating Unit:

Keep at least three feet of clearance around your furnace or heat pump to allow proper airflow and safe operation.
