How often should I change the air filter in my home’s HVAC system?

While each home will vary, we usually recommend changing the air filter(s) in your home’s HVAC system every 3 months. Keep in mind that having pets or doing renovations in the home may be reason to change them at more frequent intervals.

Pro Tip: Set a reminder in your calendar because these can be easy to forget!

What type of air filter should I use in my HVAC system?

While the best option seems to be a 4” media filter due to the larger surface area and improved airflow, the most common type are the 1” pleated filters. A higher MERV rating gives benefits of cleaner air from allergens and pollutants, but is more restrictive on the airflow, which puts more strain on the system. So we don’t recommend the highest MERV rated filters unless needed for health reasons. We install MERV 8-12 on most systems which catches most pollutants and allows for better airflow.

How frequently should I have maintenance done on my HVAC system?

We recommend maintenance on your HVAC system twice per year - once before cooling season and a second before heating season. This ensures that any preventable issues and safety concerns are caught before the extreme weather gets here! We will note anything that needs to be addressed and give our recommendations on repairs!

Should I replace my HVAC system?

Each system must be assessed on a case-by-case basis. There are several reasons for replacing a major part of a system or the entire HVAC system all together:

  • Once the system is over 10 years old, it is usually out of the extended warranty period available.

  • If the system creates unsafe conditions (i.e. carbon monoxide in the home due to a cracked heat exchanger), the system must be replaced.

  • If the repair costs are too high, a homeowner might opt for replacing the system versus putting a large amount of money toward an old system.
