We hired Charles A Klein & Sons recently to have central heat and AC put in our 103 year old home. Everyone from the PM Matt, to the install team, and even the office staff (Christy) were friendly, helpful and knowledgable. They were reasonably priced, did a beautiful, clean install and had the knowledge to address every one of our concerns about our old home along the way. Really can't thank you all enough!

Replaced thermostat - I later learned that thermostat is under warranty. They provided a lesser model in its place and told me they would not get an equal model. The bill was $252 - That included a discount because I am a service contract customer. I complained because the tech spent less than one hour - I think the cost is waaaaay above reasonable. I will pay it and consider it tuition. I learned a lesson and paid for it.

Critical: Professionalism, Responsiveness Their service isn't bad when you can actually reach them, but their prices have gotten to be out of control, the highest in the area. Used them for 20 years but now that they have compromised customer service for greed, we will be using another HVAC company with better responsiveness and reasonable prices.

I would give zero stars if it was an option; they were that bad. Multiple phone calls, with messages, went unreturned when we tried scheduling an initial appointment, but since they serviced our HVAC last summer, I kept trying. on 6/11, I was able to schedule an appointment for 6/16, but they couldn't give me any window of time. The technician came on 6/16, diagnosed that we needed a new blower motor, quoted us a price, and said it'd get ordered.

On 6/18 they called back and asked if they should order the part and quoted us a different price. Fine. Finally got it installed on 6/23 and within an hour after the tech left, I knew it still wasn't working right, but no way in heck was I going to try and reach them for another week to have someone come out sometime in July. Called a new company who came out same day (6/24), diagnosed, and fixed it.
