Lea Heating & Air Conditioning

Lea Heating and AC installed our furnace and humidifier and slso services our a/c. They give you a 2 hour time window and are always on time. They call to confirm appointment and when they are on the way. Service technicians always friendly, professional and thorough. We’ve used them for years and are always satisfied. They also send in the paperwork for the Union rebate. I don’t have to do anything to get the rebate. This is a good company. I recommend them.
My last technicians was Sergio. He was great!

If you'd like to see TWO things of BEAUTY, take a look at my pictures! I could not be happier!!
I'd give 10 stars if I could! This company has got to be the very BEST HVAC Company, around! From start to finish, a complete PLEASURE to deal with. They made the replacement of my old BRYANT heating and air conditioning system - which lasted 22 years - a totally stress free event.
On what was probably the hottest day of this year, my A/C died. OMG!! It was a nightmare - but not for long. I called LEA Heating and Air Conditioning and the owner himself, Mark Lea, came to my home, made my family and I feel completely at ease - NO HARD SELL - and simply went out of his way to get me the very best model for a price that I could afford. With Mark's help and that of his financing department, I ended up with an excellent system at a price that fit my monthly budget.
I had known that this Fall, I was going to need to purchase a new furnace. 22 years of service from my old furnce/AC system had been a blessing but it was time. So not only did I purchase a new A/C system installed but LEA built me a new furnace and installed it - a perfect fit within my furnace closet.
I have to repeat it again: I could not be happier!! I recieved exactly what I had needed/wanted, installed by professionals, at the exact price that I would be able to afford on a monthly budget.
THE BEST! Just look at the pictures! A thing of true mechanical beauty!! Notice the pictures of the new piping and how they EVEN placed metal against the wall behind the pipe that is close to the wall to protect from heat - protection against heat/fire, I am assuming. The piping that had been there - that came with the house - hadn't had that! They ALSO placed the new A/C up, off of the ground, on a solid concrete slab. I like that!
And now, I feel secure. I don't have to worry that my furnace is going to blow in the dead of winter or that my A/C will go, next summer! And it is an important investment in my home, for the future.
This company is old school service. I believe they've been in service for like 30 years plus - check out their website to find out for sure - and I understand why. Honest, professional, helpful and dependable. The ultimate service company! What more could you possibly ask for?
Thank you so very much Mark, Robert and the nice gentlemen who came and installed my system. I appreciate your kind service more than you could ever know.

Very pleased with the recent installation of a replacement a/c unit at my house. The previous unit was also purchased from, and installed by Lea Heating & Air Conditioning. I will highly recommend to everyone in need of HVAC service and equipment.

Kenny arrived on time. Got right to work replacing filters, checking to make sure the numbers were right, and cleaning. He said things were good and would see us in a year. He was very professional and personable.

We had our furnace and A/C replaced by Lea last year and the system was great! This visit was for preventive maintenance and the service worker checked and cleaned the equipment and was very professional and friendly. We’re looking forward to a cool summer! Want great quality and service? Give yourself some “Leaway”

I had a new a/c and furnace installed. They did a great job. Mike and Robert gave me a couple of options. Their crew came out installed it. Everything works great. I recommend them for any kind of a/c or furnace work.

Lea Heating & Air Conditioning provided exceptional service and quality from beginning to end. Starting with Mike and his expertise and professionalism during the sales process to Doug and Josh going above and beyond at the time of installation and ending with follow up calls from Robert and Mark, their team exceeded all expectations. Would highly recommend!

The crew of Jesse, Josh, and Johnny replaced our central air and furnace recently; and they did a great job! They were efficient, courteous, knowledgeable, helpful. They're very good at what they do! We're very glad they installed our equipment and that we chose Lea for our HVAC needs!

Technician was on time and efficient and very professional. I would recommend Lea Heating in a heart beat. Quality work ethic and very reasonable. Thank you Lea Heating.

We purchased our home a couple of years ago and have dealt with Lea Heating on a couple of items; filter replacement, thermostat assistance and annual unit maintenance/inspection. They have been absolutely outstanding to work with. From the Service folks in the shop to Kenny our in home tech…. They have been GREAT.
