For the average household, the cost of water heating adds up to $400 to $600 per year. Water heating accounts for approximately 20% of your total energy bill. A new hot water heater is an opportunity to increase efficiency and trim expenses. Rather than wait for the disruption of sudden failure, consider the benefits of taking proactive measures. If your water heater isn’t quite meeting your needs, is approaching or past its life expectancy of 10 to 15 years, call Lea Heating & Air Conditioning for a free estimate in Northeast Illinois.

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 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

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

Dorinda Fucarino

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.
