Everything You Need to Know About Furnace Filters

Furnace filters are an integral component of an HVAC system. There are a variety of sizes and options available when talking about filters, and it is no wonder that most homeowners have so many questions about furnace filters! In this article, we will help you understand furnace filters more – how they function and how you can choose the best one for your HVAC system and your home! 

WHAT ARE THE DIFFERENT TYPES OF FURNACE FILTERS? 


Furnace filters can either be disposable or reusable. Disposable models are the one that is simply pulled off from the unit and just replace them with new, clean ones as needed. Reusable or washable filters, on the other hand, can be removed from the filter cabinet, cleaned accordingly, thoroughly dried, and reinserted in the filter cabinet for continuous provision of quality air to your home. Disposable furnace filter options are as follows: 

*Fiberglass filters 
*Polyester filters 
*Synthetic media filters 
*Electrostatic filters 
*High-Efficiency Particulate Arrestance (HEPA) filters 
*Pleated media filters 

MERV - What does this mean? 
Minimum Efficiency Reporting Value (MERV) is the rating system used to express the efficiency of furnace filters. MERV ratings range from 1 to 16, and when reading it, you have to remember: the higher the MERV rating, the more efficient the filter is at capturing contaminants of different sizes. 

Filters that are rated MERV 8 through MERV 12 are known for offering excellent air filtration for residential properties. While you might think that it is best to purchase the highest MERV-rated filter, using such filters can actually restrict airflow through your HVAC system. This can cause comfort issues, system breakdowns, and increased energy consumption. 

HOW LONG DO FURNACE FILTERS LAST? 
The service life of furnace filters can vary depending on different factors. The efficiency rating of a filter greatly affects its lifespan. For instance, filters with higher MERV ratings can typically last longer than lower-rated, low-efficiency furnace filters. 

There are also factors concerning your household that can impact a furnace filter’s service life. For instances, homes that have pets or smokers have more airborne contaminants. The filters in such homes need to be changed more frequently as their filters can also become clogged faster because of the presence of more contaminants. If there are people who are suffering from asthma or allergies in your home, then you should also frequently change the filters to help reduce airborne triggers inside the home and thus, lessen the symptoms they are suffering from.

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.

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.

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!

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!!

Great service and great people to deal with, from sales to installer. I highly recommend this company.

by GR from Oshawa on Twintech Heating and Cooling

Twintech replaced our aging furnace and air conditioner recently. I highly recommend this company. Their quote was competitive, they were on time and respectful of our home and extremely professional. From the salesman to the installers and the owner who followed up afterward to ensure we were satisfied, we are very pleased with the service. We are looking forward to working with this company for all of our HVAC needs for the years to come. Excellent workmanship and service!

We wanted to get our AC replaced as it was 22-years old and added to this our furnace was costing more and more to repair. So, we decided to get both the furnace and AC replaced.

After going through a few quotes and product reviews we decided to go with Twintech. The three-men crew arrived early in the morning, wasted no time and got to work right away. By 2:00 pm, they were all done. I’ve found their work to be top notch and they were completely professional. I had all my questions answered to my satisfaction both during the progress of their work and at end.

I have pleasure in recommending Twintech to anyone who is looking to get their furnace or Ac replaced

Our air conditioner died On a Saturday and within hours Dave came out to take a look and discuss replacement/repair options.
The new air conditioner was installed on the Wednesday. The new unit was installed quickly. The installers were friendly and cleaned up afterwards.
We noticed a slight leak around the furnace that night and they came out the next day and fixed the issue. It has been working great and is quieter than our previous unit.
Very satisfied and would highly recommend TwinTech.

by Nancy in Toronto on Twintech Heating and Cooling

I contacted TwinTech to replace my 20-year old A/C. Dave, their service rep, promptly replied and was at my home within 2 hours. He was friendly and knowledgeable and didn't try to upgrade or oversell their A/C units but suggested the best fit for my small 1000 feet bungalow. Although this was during a heatwave and very busy, they were able to fit me in 2 days later. The TwinTech crew installed a 1.5 ton Ducane A/C unit that is now running smoothly while maintaining a constant cooling temperature. The crew were very courteous, professional and efficient and I will definitely recommend TwinTech to family and friends. I much appreciated your great service.
