We have been using Lea Heating for years. They have done everything from season service to a/c and furnace repairs. Recently they replaced an a/c unit and furnace. Lea Heating has done a fantastic job for us and we would recommend them to anyone looking for an HVAC company. They answer the phone. They provide quotes in a timely manner. They assist in procuring an rebates available. Their pricing seems more than fair. The work is done on the day they schedule and completed on time. When they leave there is never a mess and we fully understand what was done along with them training us on new systems when needed.

My furnace went out on Thanksgiving day. Lea Heating & A/C were out in a couple of hours to fix my furnace. They were great and professional. I would recommend them if you are in need of help.

I’d give more than 5stars if possible. Top notch experience from the first phone call with Robert and the meeting to go over our options with Mike and the 2 day install with Doug Josh and Tyler (and a couple more guys the first day working incredibly hard moving equipment in and out through the snow). We needed more than a straight forward HVAC install. We needed Mike’s professional advice and direction on how to cool and heat our entire house on one system because we currently had 2 systems (one not cooling and the other 20+ years old on its way out). Mike gave us 3 different ideas on how we could proceed. And then he put together 3 different systems so we had choices based on our budget. He was thorough and honest and helpful and patient. He took my numerous calls and in the end was able to save us money on an energy efficient system that would handle the entire house. This was a huge job for the installers. 2 HVAC units to remove and one giant unit to install -duct work to install and electrical work had to be done and new piping and pvc venting had to be put in. And on and on! These guys worked so very hard and they were constantly cleaning up the area. They left our room cleaner than it was when they arrived. Amazing work ethic and they could not have been more friendly. DOG LOVERS! That’s always a bonus when u have nervous pups around the house. I felt like they completed this job as though it was their house and they wanted everything perfect neat tidy and done to perfection. I’m not exaggerating either. I am a perfectionist to a fault and I was so very happy with everything from start to finish. The best part about this experience was knowing after the installation Lea Heating will be here for us when we need them. I am 100% sure of this. I would recommend this company without any hesitation and you will be treated like family.
We had a hard time with a previous company we used and what I have learned from working with Lea Heating is that when u make this investment in your home it’s not just purchasing equipment it’s trusting a company to be there for you for the life of the system you purchase. We found just that with Lea Heating.
