Testimonials

On 7/17/2026 Roger H. had this to say:
We are extremely happy with the services provided. Lenny has been our furnace service provider (whenever we called) for approximately 15 years. He has always been prompt, polite, knowledgeable, and respectful. We had him and his son, Will, replace our furnace this past winter, with the plan to replace the air conditioning unit in the spring. Will came to replace the air conditioner when we requested, and upheld the same professionalism as his dad. We are very happy with the end results. We would (and do) recommend Lenny's Heating and Air Conditioning. Roger and Vonda

On 7/5/2026 Tyler Gentile had this to say:
Ac finally croaked and Lenny's team came out same day, and when I say the tech tried everything to save my old unit they dead. He even said sorry when it was clearly toast, they didn't even charge me for that call because I got a new system from them which they came out 2 days later to install. They even came by on the 4th to get measurements, they don't make technicians like this anymore. Great service, great work ethic! Couldn't be happier.

On 6/17/2026 Emily Phelps had this to say:
Recently bought a home & moved to the area. Lenny's was our first call as a few weeks in our AC went out on one of the hottest weeks. Will was very responsive and out the same day, literally a lifesaver! It was deemed we needed a whole new system due to the age and parts. Was installed the same week. Over all very accommodating, friendly, reasonably priced and quick to action. They will be the first call in our book!

On 6/2/2026 Sarah Pittz had this to say:
