A central air conditioning system offers many advantages over conventional air conditioning systems. Undoubtedly, central air is one of the most effective and efficient ways to circulate cool air throughout the house. However, central air conditioners offer one major benefit as they help improve the indoor air quality of your home. Centralized units send cool air directly through air ducts or vents located in each room, cooling your entire home to the desired temperature. Please note that second floors are a little harder to cool, as cold air drops.

We recently had a new furnace and AC unit installed by these folks. Chael was great to have do the work. We have done business with Lakeside Heating and AC since moving to the area a few years ago. They are extremely competent and very customer oriented. We recommend them highly!

Lakeside replaced our furnace and water heater. They were very clean and did an awesome job!! It was great service

We couldn’t figure out why our air conditioning kept shutting off during the peak of the day ( on what seemed to be random days ).
My dad is handicap and needs to be on the cooler side! So this was a big concern for us, Tony came out and fixed us right up!!!
Thank you so much for helping us get our AC figured out!!!

We have had a wonderful experience with our furnace and air conditioner replacement. The customer service we received exceeded our expectations. If we ever need any future service Lakeside Heating and Air Conditioning will be first on our list

Honest, knowledgeable, and reliable. We’ve worked with Lakeside on both our A/C (replacement) and our water heater (fix), and were pleased with their service on both. Highly recommend.

I finally had the last Lennox furnace that Lakeside Heating & Air Conditioning installed for me 32 years ago replaced today! It was still working, but I decided it was time. It was like saying good-bye to an old friend who was always there for me as I raised my children as a single parent. Lakeside Heating has always given me reliable, courteous service which I can always count on. I have referred them to other people and will continue to call on them for yearly maintenance.

Whole home steam humidifier quote and installation.
Everyone at Lakeside was knowledgeable and professional. Unlike some other companies we had out to quote, the technician had a thorough understanding of the needs for our home and answered all of our questions. The quote was fair and the installation was performed around our schedule.
We will be going to Lakeside with all our future HVAC needs!

So, after a very thorough and professional quote from owner Tony, two very competent, polite and helpful installers + one professional electrician were here less than 5 hours and completed my installation. Removed the old unit and put in the new Leonx. It all went very cleanly and smoothly.They answered my questions and offered the kind of experience I wish I received every time I needed work done at my house. And my neighbors are happy for their referral $50, too! Thank you, Lakeside!
