How-To & How Often to change your Home’s AC Air Filter

Watch as we walk you through changing your AC Filter with our short video below

Did you know, that changing an air filter is the fastest, cheapest way to lower energy bills and increase the life of your hvac system?


  • Step 1 – Turn off your system
  • Step 2 – Locate your filter, or filters, usually near your thermostat, but sometimes at the unit itself.
  • Step 3 – Remove the old filter
  • Step 4 – Insert your new filter, make sure the flow indicator is facing the right direction for proper air flow.


We recommend replacing your standard thin air filter at least every 3 months. And the thicker 5 or 6 inch air filters every 6 months. Here are 9 Proven Tips To Reduce AC Bills.

This will help your hvac system to run smoothly and will cost less to keep you comfortable.

Wondering which filter to purchase

Purchase the highest MERV (Minimum efficiency reporting value) Rating number you can afford. This will filter out more dust and junk from the air. Remember, this filter isn’t just saving your ac system, it’s filtering the air you breathe. Going cheap here might not be your best option.

GL gave me the best heater service and repairs that saved me thousands. He now has a new customer for heating service and repairs. I am glad that I made that call. I am a very happy customer.

Craig S

Lewes, DE

Very reasonable fees, seemed sincere and not just after the quick buck. I highly recommend his heating and air conditioning company, and will use him for additional services.

Gary arrived on time, was very professional and completed the heating system repair work in a timely manner at a very reasonable cost. I would recommend his company based on his honesty and integrity of service. I had an estimate from a larger company and they said it was very complicated and would take several hours. I knew better and Gary did the installation in 25 minutes and charged accordingly.

Linda M

Dagsboro DE

Very professional. Called immediately after talking to his secretary to set up an appointment. Fixed my heating and also did adjustments to my 2 heat pump units that should have been done by original hvac installer. Will call them again for heating and air conditioning service, and I recommend them to anyone needing HVAC service.
