24/7 Emergency Service 847-305-2800

Timely and conscientious ductwork service is essential to the performance of the HVAC system. The efficiency, capacity, reliability, and longevity of your furnace and air conditioner are directly affected by the duct system. The integrity of this branching network of pipes significantly impacts your comfort, health, safety, and budget. Because heated/cooled air travels through the ducts multiple times per day, even minor issues result in huge consequences.

What others say


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

I’m very pleased with Lea heating & Air, I had a quote done, very reasonable price, i called scheduled an appointment for whole HVAC system install, Ron & Joshua were professional very knowledgeable, never messy, after the job was complete they both explained everything to me, these two guys know what they’re doing. I would highly recommend Lea to everyone, they’re awesome!

Dorinda Fucarino

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 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

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 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.

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

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!!!
