Furnace Air Filter Tips

Air filtration is essential for your home’s comfort and health, but how do you know when it’s time to change your filter? Or which filter is really the best? Here are a few handy furnace air filter tips from the heating system repair experts at Precision Air and Plumbing:

  • How often you change your filter depends on the type of filter you use, the size of your home, how dusty it gets, and whether you have pets. Furnaces in large homes clog filters quickly, as do those in homes with animals; these homes should change their air filters monthly, while smaller, less populated homes should change them bi-monthly.
  • Buy your air filters by the case and store them by the furnace, this is not only more cost-effective, but also reduces procrastination.
  • Get in a filter-changing routine, just like you do with your car’s oil, set reminders on your smartphone or simply mark it off on a calendar. This simple act could save you hundreds of dollars in heating system repairs.
  • Never run your forced air system with the wrong-sized filter: a filter that doesn’t fit correctly allows dust and other particles to slip around the filter and into your home. This results in clogged air conditioner coils, which lowers the compressor’s efficiency and lifespan.
  • Always turn your furnace off at the breaker panel or disconnect, not just at the thermostat, before you replace the filter. Electrical wiring is very close to the filter location in some furnaces, which could shock you if the power remains on.
  • Finally: never guess. If you are unsure about any aspect of your air filter– its type, size, location, or condition– call a professional.

I wanted to make sure my air conditioner was ready for summer. Fernando came out and made sure my unit was tip top. He was friendly, professional and not a sales man. Thanks Fernando!

We woke up in the middle of the nite on memorial day to a hot house. I called precision at 6am and they were here before noon. Simple problem fixed, cool house. I love these guys!

Thank you Ray at Precision Air...the compressor on our AC went out last night and the house was HOT. This morning Ray was there to replace the compressor and had us feeling the cool air again in no time. Great customer service...quick response time and friendly from the first call until the repair was completed. Ray even offered to clean the filters! Thank you!!

I’m so glad I called Precision for my annual AC checkup!! Austin was professional, super friendly and answered all my questions. I’ve had more bad experiences with AC companies here in the valley than good ones. Precision Air will have all my hvac business going forward!! Thanks for being a reputable and honest company!!!

He did a great job; professional and knowledgeable! Kalin is the technician’s name and Precision Air and Plumbing should take a bow for hiring such an invaluable employee!!!

Precision Air is a company of integrity. I signed up with them August 1st, 2019 for their AC maintenance plan for 2 years... Someone from their office called me a week ago to set up their yearly maintenance visit. SO GRATEFUL.

It was time to replace our AC, and so our choice was Precision Air, as we've been with them for over 20 years. Teman & Julian did an excellent job on the installation today, arriving on time.
