Tankless water heaters offer all sorts of unique benefits. Approximately the size of a small suitcase, the unit mounts on the wall, freeing up a great deal of space, and providing on-demand hot water. Because water isn’t repeatedly reheated in a tank, absorbing contaminants and using up needless energy, you enjoy cleaner water at less cost. Plus, this energy-efficient alternative is especially long-lasting.

Jared was Rick’s support Tech on our new Bryant Air Conditioner Installation in March 2020. He did an outstanding job working with Rick. He is a great asset to Lew’s and his team members. They also take care of my Boiler Heating System. I would recommend Lew’s to my friends. Thank you for being there.


My furnace stopped working in cold December weather and Lew’s was able to send a technician out the same day. The technician was friendly, knowledgeable and honest. To fix the problem, the tech needed to order a part, which came (and was installed the next day). My husband and I are very thankful for such great service and having our house nice and warm again!!


We were very happy with Lew’s Installation of our new furnace and air conditioning. The installers were knowledgeable and professional. The prices were fair and comparable.. We will definitely use them for future heat and air conditioning needs.

Furnace was not feeling well… cold Ohio weather! Called Lew’s spoke with Lisa in the office and she was able to have someone come out the next day. Ed the technician showed up on time and was able to diagnose called his office and another office lady I believe her name is (Autumn) drove the part halfway to meet the technician so he wasn’t wasting time. The entire staff went above and beyond for me. Thank you!

I had Lew’s come out today to check and see if I could get by with replacing an inducer on my 29 year old furnace. Ed, the technician checked out the furnace condition and said while the furnace is definitely older, it looks in good shape and may last a couple more years and installed the inducer. I appreciated their prompt, HONEST service. No high pressure in trying to sell me a new furnace. When I do get a new furnace I won’t think twice about purchasing it from Lew’s! and thanks Ed, you were very easy to work with!!!!
