I could not be more pleased with this company, Andy Brice, Eric Kenny, and Rodger, you gentlemen deserve a raise. Even the nice lady in billing was awesome to deal with. Sorry, I did not catch your name.
Priced reasonably, efficient, professional, diligent, knowledgeable, on top of their game, reliable and I could go on with positives…
It was such an awesome experience!
Unfortunately my hot water heater went New Year’s Day. I got First Class’s number from Home Depot. I reached out to Andy and he sent Eric over to give me a free estimate. The next day Eric and Rodger came and did a superb

There is no doubt that Chris W is an expert technician who checks all the boxes. He put booties on entering the house and crawled into a crowded awkward spot to service our heater. He was on time, efficient and explained the status of our heater in a language we could understand. Truly an asset to the company...

Techician showed up 3 hrs after a 4 hr window! Wanted to charge me $1,300 for a fan motor. George Hoffman heating and AC was contacted for second opinion. George replaced the fan motor for $236! First class is unethical and dishonest. Do not use them!

Mike T just completed our HVAC seasonal inspection. Found two things that could have become big issues if left unattended. He is very polite and thorough and we appreciate his attention to detail.

I concur with Jeffrey Rineer’s review from 3 days ago, My experience is EXACTLY the same, I called today and was told that I couldn’t get an appt for hvac maintenance until Dec. 20. That is untenable as I have had no problem in the past with First Class HVAC. During phone call; I find out that Horizon has taken over….no notice from First Class about this change. This is NOT first class service, I will be switching my HVAC company ASAP

We had a H2O filtration system installed 2 years ago and was completed in a timely manner. Last year they came out and replaced the filters all this done at very reasonable rates. Now under the Horizon umbrella when they came out for Filter replacement Blake the master plumber went far and above not only to replace the filters but physically cleaned the original installation to a professional one. Horizon has made a big difference in this company.

Terrible service. Took 4 months to get a running new HVAC system. Techs are not experienced, management could care less. Don't use this company

We have a service contract with them. They have cancelled on us now 3 times. Since they sold out to Horizon, the services has been terrible, and First class will not service our area any longer. They owe us two service agreement appointments still. The unit is still under warranty and now we have to pay out of pocket to have a reliable company come out to do the service.

The service tech showed up an hour and a half after the scheduled FOUR our window. Apparently the diagnostic fee does not cover the actual diagnostics because the tech required a fee of $400 or $1000 to actually diagnose the issue, which a more reliable thorough service company diagnosed for the original diagnostic service visit fee, performing what Fist Class required $1000 to do. To add to my displeasure, the other companies quote to repair the issue was $2000 lower. I would not recommend utilizing this company for service.

I have been a customer of First Class Heating for years, only to find out today AFTER I signed a one year contract that FCH was purchased by Horizon Services. NO ONE at First Class alerted me or folks that I sent to them over the years that they were being purchased. How am I to know if the quality of service is going to be the same? Typically when these buyouts happen service goes down. Why did First Class NOT alert it's customers of these sell off?

How did air conditioner put in last late summer and I thought everything was OK but the condensate pump underneath the house stopped pumping water so I went underneath the house to see if they became disconnected or what. Come to find out that the air conditioner is pumping 15% at least 10 to 15% cold air into my crawlspace because they did not… seal the Plenum onto the air conditioner. And left a huge mess underneath Underneath the house. Not happy one bit so what this means is it’s been pumping heat and air-conditioning into my crawlspace since last summer.

I made an appointment for July 16, 2021with First Class for a tune up of my A/C unit. This appointment was made a couple of months ahead of time. Two days before this appointment, they called and canceled it because they said they had so many other jobs to do. So much for making an appointment! Then about a week later my air conditioning unit stopped working, so I called to see if they could give me back my appointment. They set me up with another appointment but this one is going to cost me twice as much! I just received a call and they informed me they had to change that appointment as well.

Shout Out to First Class for coming to my rescue! I just moved into my house and the heat was not working. I called around 3pm and Jim was at my door in 1 1/2 hours. Jim was the tech of the hour for ensuring I had heat on my first night! Thanks First Class Heating and Air Conditioning for prompt efficient professional service when I needed it! 🌟🌟🌟🌟🌟

Kyle just completed our winter check up. Courteous and professional, he explained everything he was doing and gave tips to avoid repairs. Wore his mask the entire time he was here and shoe covers anytime he came through the house. Excellent job, as usual.

Jim came out and serviced my cooling system. He is very knowledgeable and takes great pride in his work. He quickly diagnosed the problem that had been previously misdiagnosed. My cooling system is working now.

I have used Ocean Air for my client's properties previously and been very satisfied with their work and customer service. Recently I called them (when our A/C stopped working on the first 90 degree day of the year) and they went over and beyond to get out to us within the day, despite all of the service calls they had. We will definitely be using Ocean Air exclusively from now on!
