Lea Heating & Air ConditioningHVAC Services in East Dundee

I have used Lea heating and air for over 20 years

From choosing the right system to installation, the team was great. They listened, answered questions and were thorough in all they did.

Lea Heating has always been great to work with. There employees have always been respectful when ever they come to my house. i have recommended them to several people, and they are all very happy with them.

Installers were very courteous, professional, clean and efficient. They fixed a small PVC drainage issue in my utility room (unrelated to the install). Answered any questions I had and helped walk through my new equipment with me.

I've been a customer for 15 years now, and have never even second\-guessed any of their services or recommendations. For this latest project, they completely replaced both my 20 year old furnace and 15 year old a/c (which was on the old freon system) in less than 6 hours. The install team was friendly and relaxed and did a great job protecting my space during the work.

Experienced installers were quick and great getting job training. Friendly and did good job training on new thermostat and system

All 3 installers were very professional, courteous, and knowledgeable. Each one asked whenever they had to access / use areas out of the furnace room. Equipment operation was explained to me. All paperwork was reviewed and explained.

Always available when needed, expert service

Very professional and very pleasant to deal with. Highly recommend to all.

Honest, dedicated and professional.

Overall good experience

The Lea team went above and beyond on all aspects of the transaction. From initial consult, installation and explaining all aspects of the system. A Very well run business.

My brother has used this firm for over 20 years

Professional, courteous and trustworthy heating and air conditioning service year after year!

After speaking and receiving estimates with several HC dealers we knew LEA was the best. Mike was fantastic and really cared about giving us the best products for our home at the best price. Super friendly service, polite and friendly installers who kept my husband and I involved in the process. They were also happy to answer any questions we had. Top install from beginning to end. I will recommend this company to anyone who needs a new AC, furnace, or both as we did.

I would highly recommend Lea Heating for their service and work.

Great people, products, pricing. We were 100% satisfied with every step of the process.

I have been using Lea Heating and Air for 35 years. Always professional, knowledgeable, and trustworthy. I just had my furnace and AC system replaced by them, and from the sales consultation through the installation, they were great to deal with. They were never pushy; they were interested in making sure my needs were met. A+ as always.

Did a great job. Very thorough and patient.

Explained all details of new system. Kept me updated about installation

Installed new furnace and a/c quickly and cleanly. New Bryant furnace is so quiet. Lea price for project was lowest out 4 quotes I obtained.

The furnace install looks great. The sheet metal integration with my original duct work looks seamless and original!

Great company to deal with, very honest

Good

Service was excellent. The technician found and corrected an issue with the duct in the furnace. System performance is much improved. New A/C is more efficient.

The Team at LEA Heating did a wonderful job of presenting options and delivering a quality installation. From Sales to Install, the staff work flow proved that their company offers value plus service to its customers. They are not only committed to the customers but their company is committed to the community.

All installed and working

Lea just replaced my 33 year old Bryan furnace and air conditioner that they originally installed in 1989! The new Evolution Extreme AC unit and Evolution 80% furnace were replaced in about 6 hours with their crew of three. The installation crew was professional and cleaned up well after themselves. Mike Lea did the quotation and was my point of contact. Mike, if I were to make one suggestion, your quotations were very detailed. However, it is 2022, they should be typed, not handwritten.

Moved things areound to get me in sooner because of my age. They were here even a bit earlier than expected. That was great.

Great service and price. Work done on schedule.

I had a 35 year furnace/AC and was very impressed with the installation of the new system at my house. I work in the trades and knew there would be no easy part in swapping out the units. These guys nailed it.

I have been a customer of Lea heating and air conditioning for over 30 years. They have always been there to help. Whether it is service, repair, or replacement the Lea family has always given us excellent service!!

Showed us exactly where our issue was and the choices we had

They are efficient and have a wealth of information. Install was excellent. Showed up on time and cleaned everything up afterwards.

Couldn't ask for better!

Excellent service, most highly rated.

Flawless installation

Happy with service and product recommendations.

pleased with dedication of installer and his ability to solve problem (old house)

It's very refreshing to work with a company that goes the extra mile to take care of their customers. I am so very pleased with my new air conditioner. The unit is quiet, looks great and cools my house quickly and evenly. The installers came in, they covered the floor, pet the dog and took care of business. I highly recommend Lea Heating \& Air Conditioning. The owner Mark quoted me to the penny, what it would cost and even told me what I didn't need, saving me money. You won't be sorry if you contact Lea for your Heating and air Conditioning needs.

I had purchased an air conditioner from Lea Heating and Air in 1989, and the Unit is still running FINE ( Knock on wood now! LOL) Other than needing regular maintenance, which was also very little. So I just had them install a whole new air conditioner system, a/c unit and fan, in my new house and it is fantastic. They we're fast and efficient. And I had shopped around comparing prices and they were by for the best, a couple $1000.00 cheaper! And my house is one large room with 7 sky lights and and 4 sets of Sliding glass doors, literally impossible to cool in July and August. They kinda reconfigured the return vent, and it is soo much more practical now. Now of the other places had suggested this. And Lea Heating also replaced the old return vents with new out put vents. and this was all still included in the fantastic quote they gave me! So having said all that you'd be a fool not to give them a call!! I HIGHLY recommend them!

They promptly scheduled the install of furnace / A/C combo. The guys showed up promptly, worked as expected\- heat was off for a total of about 6 hours. The only negative I'll state is that they broke my Honeywell whole house humidifier by trying to bypass the pressure sensor and re\-wiring it directly to the furnace control board. It didn't work, and it sprayed water out of the unit. Unfortunately, they had destroyed the pressure sensor and couldn't reinstall it to the Honeywell directions. They hinted that it was my fault for buying a "cheap" Home Depot humidifier (it was a $300 unit), and left with it shut off\- for me to deal with. I ended up purchasing the pressure sensor from a parts house, reinstalled it myself, and it works as it did before.
