Ductless AC & Heating Services From an Expert Team

We’re very familiar with the many rewards of ductless technology. This compact, innovative and versatile style of temperature control requires little more than a small hole in an exterior wall and access to electricity. Indoor air handlers permanently mount up high on the wall or in the ceiling, operating quietly and efficiently and providing the personalized comfort and cost savings of zone control. You can even program and make adjustments through a cordless remote or an app on your smartphone.

Reasons to Choose Ductless AC & Heating

  • Increase cooling or heating where the ducted system’s airflow is lower
  • Easily add AC & heating to a home addition
  • Save money on installation costs with a simple wall-mount design
  • Offers personalized zone control for a targeted comfort solution
  • Safer & more efficient than space heaters & other smaller solutions

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

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’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

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 and cooling for 8 years,top notch company, they are on time, attention to detail and work is perfect. Clean up is best in class. Todays LEA rep was Duane, and he is a true professional. Great company.

Jon Trent

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.

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!!!

Rick Adkins

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!
