24/7 Emergency Service 847-305-2800

At Lea Heating & Air Conditioning, we often get asked how often an air filter should be replaced. Because the conditions in your home are unique, it’s impossible to predict. We recommend checking it often and if the filter looks dirty, it needs to be changed. Neglected air filters quickly become clogged, restrict airflow and negatively impact heating and cooling efficiency, capacity, reliability and longevity. For assistance choosing the right filter for your needs, proper installation and any questions at all, simply give us a call at 847-305-2800.


Professional Air Filter Installations

Air filters are available in a wide range of prices, sizes, and styles. Better quality options capture more contaminants, smaller particles and require less frequent changes. Consider the investment into high-efficiency electrostatic filters that can trap bacteria, dander, smoke particles, and odors if:

  • You tend to forget the upkeep of your furnace or air conditioner
  • Have pets
  • Anyone in the household suffers from allergies or asthma
  • Anyone in the household smokes

Contact our team for your air filter services & repairs!

Have heard of a MERV rating? Minimum Efficiency Reporting Value ratings indicate the effectiveness of the filter, with a higher rating for more effective options. However, the right filter for your needs might not necessarily be the highest MERV rating. It depends on how often you plan on replacing it. We encourage you to let our NATE-certified, factory trained and experienced technicians provide knowledgeable assistance. With over 40 years of service, we at Lea Heating & Air Conditioning are your air filter experts and offer affordable IAQ service across Elgin, Crystal Lake, Carpentersville, Algonquin, West Dundee, Sleepy Hollow, East Dundee, Lake in the Hills, and Hoffman Estates, IL.

What others say

We had a new AC & Furnace installed one month ago; everything is working perfectly from day one. Mike came out initially and gave us a few options that would work with our home, was very helpful and answered all of my questions. Andy and Jordan installed our new AC & Furnace in a single day, amazing job considering we have a very cramped utility closet. Very pleased all around, I highly recommend!

Kyle Stewart

I highly recommend Lea Heating and Air. They are very fair priced and knowledgeable about what needs to be done. Josh and Andy installed my central air yesterday. I’m very happy with their work. Both were friendly and very efficient. They took the time to answer any questions that I had and cleaned up beautifully. Thank you again for a job well done!!

Kristi Weseman

Mike Lea was wonderful giving me a quote, explaining the price, discounts, the process etc. The crew was friendly, worked like a well oiled machine and explained what they to doing. I purchased a furnace, A/C, humidifier & thermostat. Everything was cleaned up when they were done and I couldn’t even tell they had been at my home. Fast, efficient and good price! I highly recommend Lea Heating & Air Conditioning.

Patti Flessner

I had an issue with an update on my thermostat. I contacted one local company and they had sent two guys out that had no idea what the issue was. I then contacted Lea Heating & Air Conditioning. I had the opportunity to talk with Robert and he went “way out of his way” to help me out. Outstanding customer service! He is very knowledgeable in his work, was pleasant to work with, and was reliable. Outstanding companies like this are hard to find. I will always call them first for any work that needs to be completed. I highly recommend them!

Brandon L.

I used Lea Heating for a normal maintenance service check up in my new townhouse. They were able to accommodate an early morning appointment and kept within the time frame quoted. Duane answered my questions politely and gave me good information for future heating/cooling situations. I would use this company again.

Nancy Roozee

From the estimate to the install, everything was excellent. With being a retiree from the trade world, the work was clean, started on time, finished on time, very impressed! Would highly recommend!!!

Rick Adkins

We have used LEA HEATING and cooling for 8 years,top notch company, they are on time, attention to detail and work is perfect. Clean up is best in class. Todays LEA rep was Duane, and he is a true professional. Great company.

Jon Trent

We have used Lea Heating services for 20 years. They repaired and maintained HVAC in our large family home in this area and replaced the furnace and air conditioner when required. Now that we downsized to our “retirement” home, we knew immediately they were the ones to call for this place too. They have always been responsive, professional and pleasant too. They provide information and answer questions, do not pressure sell and provide quality equipment. Yesterday they installed a new furnace and air conditioner in a timely manner, were considerate, clean and helpful in their approach. One gentleman even carried in some groceries for me! They left the site in tip top condition with everything working. Highly recommend Lea Heating.

Mary Loete

I would highly recommend Lea to everyone, they’re awesome!
