Change Your Air Filter For Cleaner Air And Better Efficiency

March 30, 2015

Your furnace needs regular maintenance, and one of the most important upkeep tasks is an Air Filter Change. When the air filter in a HVAC system is clean, the unit runs better, parts last longer, air quality is healthier and energy bills are lower.

Can you do an Air Filter Change yourself? The answer is yes, but there are some things you should know before attempting this simple chore.

First, HVAC filters come in different sizes and types. To check your furnace filter’s size, just look at the existing filter. The part will have the size and filter media printed right on it. Also, you can check the furnace owner’s manual. Additionally, the filter will have arrows to indicate the correct way to insert it into the furnace.

Second, most air filters should be changed every 3 to 4 months. For the best efficiency ask a HVAC pro or consult the owner’s manual.

Third, air filters are made of different materials. Your choice can, in part, depend on your budget and what you are trying to accomplish with the filter. Air filter types include:

1. Fiberglass. This cost-sparing filter medium does a good job. A favorite with homeowners because it is readily available at home and hardware stores, fiberglass may have to be changed more frequently than other kinds of furnace filters.

2. Media air. Used mostly by HVAC professionals, this multi-layered filter works well and is very durable. Most home owners, however, do not use it because it is not commonly stocked at the corner home outlet.

3. Pleated air filters. They have a lot of surface area to trap dust, dirt and other contaminants but also allow for free flow of air from the HVAC units.

4. Activated carbon filters contain charcoal. They excel at eliminating heavy and persistent odors from the home environment. They are not as useful for trapping particulates such as pollen and dirt.

5. HEPA filters. These are High Efficiency Particulate filters which get rid of pollen, pet dander and other allergens. They are very helpful to asthma and allergy sufferers.

Call our service phone number today to schedule a basic HVAC tune-up and to ask what filter may be best for your home.

Daniel B. went above and beyond fixing my air conditioning equipment today. He explained everything to me and made sure I knew exactly what he was doing throughout the process. My issue was tricky and he was able to figure it out and fix everything. Daniel is also incredibly kind and personable and made the process easy for me. I am completely satisfied with the service and will be contacting Daniel again for all my HVAC needs!

Ariel A. performed outstanding services! It was his first visit and he asked for an orientation which I thought was a very good approach. He wanted to make sure that he covered all the areas. We have been a customer of Brody Pennell for more than 30 years, and I can honestly say this young man is in the top 10% of the employees who have had the opportunity to service our home.

These guys are total pros. They know what they are doing and they explain everything clearly and the pricing is very transparent. Ivan and Jose C. are very friendly and efficient. I have just had a second very great experience with Armando. He came to maintain the heating system and was very thorough and efficient.4/15/2024: Ruben and Phil just came by to do maintenance on my ac system. They were so friendly and explained everything really well. They inspired total confidence. Another great Brody Pennell experience.

Our old furnace was about at the end of its life. After discussion with our favorite technician Marco Ayala we decided to have a heat pump installed. A crew arrived this morning headed by Edwin Cabra. He was assisted by Diego B, S. Ramiro, Edgar H, Jonathan A. This team was well trained, worked well together and was finished this afternoon! Great job by all. That's why we have been customers for more than 15 years!!Update: there was a small issue with one of the wires. Ruben Medina found the issue and corrected it. Again Brody Pennell to the rescue! Thank you again!!Further update. Giovanny Quinterro found that the outlet being used had no power. He changed the outlet and we're back to having heat. Yay! Thank you once again!!

Diego B., Sergio S., Alberto H,. And Alex S. installed a brand new system in one of my units and replaced the piping. They took a job that's usually 2 days and did it in 6 hours. They were unobtrusive to the tenants, thorough, and genuinely nice guys. Works perfectly. Extra kudos to the guys for being cool with a couple of very friendly dogs that like to jump and lick. 10/10 would recommend.

I just had David Mares here to service the A/C system that they installed 2 years ago. David was great at explaining all the pertinent information about the function and cleaning of my A/C / heating system. He took pictures to show me whatever potential issues there may be down the road. I would highly recommend Brody Pennell for the A/C / heating system and specifically David Mares as a technician.

We just bought a complete HVAC system from Marcus at Brody Pennell and I've never felt better about a manager or a company, and I'm an exacting retired general contractor. Clear choices with zero pressure or upsellng, and character as solid as their well respected company, with the resources to back it up. Marcus was impressive with his expertise, and genuine honesty well beyond that of a company representative, as the kind of person you'd look for in a friend, who seems every bit as stable as this well established company. A real pleasure!

Kevin and David provided amazing customer service for our home in Beverly Hills. They were detailed, thorough, and did not try to rush through our appointment. I received text messages from David throughout their 3 hour visit with photos of the condition of our HVAC, areas of concern, and proof of filter changes! You really can't ask for more. These guys are the best and I would highly recommend them to anyone who needs HVAC maintenance/cleaning.

Gave me a beautiful service and cleaned up as they went and tried to sell me a new filter which I’m for air purification

Brody provided the semi-annual service today. The technician was Rene Morales. Rene was prompt, professional and knew exactly what to do. Oftentimes, we are told by a vender we need a replacement, a remark which raises our skepticism. But Rene was absolutely correct that our 20-year condenser and coil running on unobtainable R22 was past its prime.Brody's personnel never disappoint. We feel fortunate to have them in our area. Happy to have Rene return in six months or any other technician. You can't go wrong.2nd reviewDuring the maintenance service the technician addressed my question about replacing the coil and condenser. He used a micro camera to look inside the furnace and advised me I still had another 5-years with the furnace. The point being he could have sold me something I didn’t need.Today the team (Diego, Juan, Bryan and Jose) came to do the replacement. They were professional, cordial and cleaned up completely as they departed. The estimate was 6-hours and that is exactly the time taken.This is a great company and certainly my go-to HVAC company.

They even checked my plumbing while under the house and told me there no leaks. Great teamwork by your company, a well deserved five star review!Update: just had my six month service done by David E. and Kevin L., what a great team! Once again, everything was explained in detail with pictures and they serviced our AC and heater. Another five star review!
