How Often Should I Replace my AC Filters?

Posted On: July 17, 2019

How Often Should I Replace my AC Filters?

If you own an AC unit, a common question you may as is, “how often should I replace my air conditioner filters?” That’s an important question to keep in mind for all home or property owners. Generally, it depends on a variety of factors, but, it’s definitely more often then you might think. A few of the biggest factors are how many pets (if any) live in the home, the level of construction and air pollution in the area, the average indoor air quality and what type of filter is being used.


It’s broadly recommended that you change your AC filters every 30-60 days, but sometimes, an annual air filter change can suffice. It really depends on the factors mentioned above. In a single occupant’s home with no pets, a good average for changing your filters is 6-12 months on average. An average suburban home may need a filter change every 90 days, and if there’s a pet in the home, every 60 days. A good way to know what’s right for your home is to check your filter weekly. If it gets to the point where you are unable to see light dispersing through it, it’s time for a new filter.


But, let’s take a look at the factor you may have the most questions about – the type of filters. On the packaging, all filters have a MERV rating [Minimum Efficiency Reporting Value]. The system is simple – the higher the number, the higher the filter quality is. However, the highest number does not always work best for your home. A filter with a high MERV rating can actually slow down your air conditioning system unless it is working in a system with high-efficiency. When you buy a filter, make sure it has a balanced MERV rating, ideally in the 6-8 range.


At Twin Tech, we often include a MERV 11 air filter with our installations. If there is no construction or pets, these air filters can last up to 1 year. This filter is 5 inches thick and can allow substantially more airflow than the typical 1 inch thick 3M. If your home air conditioner can carry up to 2.5 tons or more, you should definitely consider having a MERV 11 air filter, in order to increase air flow and remove heat efficiently.


Changing your AC filter is important for maintaining the air quality in your home. It helps your system run at the top of its performance range, which can even mean lower energy bills! If you have any further questions or concerns, you can set up a free, no-obligation consultation with a Twin Tech Heating and Cooling expert, or you can give us a call at 1.844.894.6832.

On coldest night of the year our furnace quit. At 8:40 in the morning Greg arrived and gave us a diagnosis and a recommendation. By 2:30 we had a new furnace and were warm again. Great company. Great customer service. Good reasonable price.

Twin tech team was very efficient and prompt. They provided a quote within hours of request and got the job done on time. No disruption to home function. We would highly recommend this team. Job well done.

by John from Toronto on Twintech Heating and Cooling

Our furnace bit the dust, and Twintech came out to troubleshoot and diagnose the problem within a couple of hours. Mitch was super helpful, patient, and answered all of our questions. When we decided to get the furnace replaced, the crew was over first thing the next morning and did a fantastic job. Not only did they complete the job in a few hours, but they cleaned up and respected our house as they went, and answered all of our follow-up questions. I've used Twintech for our HVAC needs in the past and will continue to do so. I'd recommend them to anyone, and it feels good to support a local, family-owned business.

by Ryan k on Twintech Heating and Cooling

Dave and the Twintech team were fabulous from day 1 and helped us through the process to identifying a new furnace and AC unit. This was our first time through this process and Dave did a thorough job explaining all the components and was very patience answering all our questions. Dave provided great insights and fair pricing.

The Twintech team did an awesome installation. Very clean and efficient. I would highly recommended their service.

by Louise in Scarborough on Twintech Heating and Cooling

We had a new Amana furnace installed by Twintech and we were very pleased with the installation. It is nice to have a warm house again.

by Private User on Twintech Heating and Cooling

Excellent job. Excellent service. Competitive price. Its rare to find a company with the knowledge and professional results we have experienced with Twintech. The clean and neat installation with attention to detail and drop sheers to respect our property is a clear indication of Twintechs high level of integrity. The 1-1/2 gas line upgrade they did for our pool 3 years ago was awesome. Can't say enough. Thank-you Twintech.

by Private User on Twintech Heating and Cooling

Twitch did a great job with the installation of our new furnace. I really appreciated their honesty and I could trust what they were telling me. Another company tried to suggest significantly more work at a greater cost claiming it was necessary to meet current building code. Twintech is very fair. All staff I meet were friendly, polite and trustworthy. I would recommend Twitch for a furnace.

by Private User on Twintech Heating and Cooling

This is a professional team that's easy to deal with. I would strongly recommend them

by hj.taggart in OSHAWA on Twintech Heating and Cooling

Very professional firm from start to finish!
They removed the old oil tank and furnace. They installed air conditioning and a new propane furnace.
Professional installation, on time and no mess.
Very pleased with their work and would highly recommend the company. Our house is three stories so they spent the time to do all the calculations to make sure we would have great performance on each floor.
Thank you again!

by susieschoeppler in Oshawa on Twintech Heating and Cooling

Upon a routine yearly maintenance, it was discovered there was a leak in the heat exchanger and a I needed a new furnace. I know nothing about these things and was completely stressed out. The company I had the maintenance plan with quoted me a huge number to rent a furnace, I just wanted to cry. Then I spoke to Dave at Twintech. He was so knowledgeable and calming, provided me a fair quote and within a few days I had an amazing crew show up to my house and install my new energy efficient furnace! I have already recommended these wonderful people at Twintech to a good friend of mine. Thank you Twintech!!

by Aaron on Twintech Heating and Cooling

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

by Linda on Twintech Heating and Cooling

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

by Robert Rogers on Twintech Heating and Cooling

We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!

by Ruth on Twintech Heating and Cooling

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
