Shawn and Tom has done great job of replacing heating system. We are enjoying the hot water. They are very professional and courteous .we are happy with the work.

Pasupuleti R.
Very happy with Genove's work. Armando discussed the project with us on the front end, thoroughly considering and educating us on the various options. In the end, we opted to install a ductless AC in one room. The price seemed very fair. The work by Richie and Ryan was carried out as scheduled, efficiently, and well. All were professional, friendly, and helpful. I'd recommend them to anyone.

Barton L.
Richie and Ryan were top notch. True professionals, they explained everything clearly. Were on time and keep the area clean when done for the day. I would highly recommend them to anyone. Great Experience.

Ritchie and Ryan were most professional and put in our new a/c competently and in a timely manner. We’ve been using Genove for our heating and a/c for many years and have always had excellent service.

My furnace needed to be replaced, and the technicians who did the replacement did a great job. The job was done on time, they showed up when they said they would, and the work was of very high quality.

I just had Genove Oil & Air replace my upstairs A/C unit and they did a FANTASTIC job! Super efficient, job was done in 2 days. They reworked poorly designed duct work and installed a new compressor and exchanger. It used to blow only warm air, but now it's nice and cold. Armando, Richie, Tommy and Ryan were amazing to work with, super friendly and their experience showed. It's hot work up in the attic, yet they never stopped working and the job was done even sooner than expected. I have used Genove for oil delivery and service for over 35 years, and they have always been quick to respond for service and maintenance for any type of issue. I am so glad I had them do my HVAC work too, it was pleasure working with them. I highly recommend Genove for any oil or HVAC services!

We had contracted to have four mini splits installed this spring and then our boiler died. So Genove has been at our house for a couple of weeks. We were very impressed with the service. They were able to replace the boiler in a very short time. The splits went in without a hitch. Their employees are on time, courteous, professional, highly knowledgeable and friendly. They took the time to explain what was to be done and what we needed to know about the operation of each installation. I highly recommend Genove for all of your HVAC needs. Thank you for exceptional service!

Cindy K.
We've used Genove Oil and Air for both oil delivery and furnace maintenance for the better part of a decade and they were our first choice when we decided to get a heat pump and mini splits installed. Armando was so easy to work with, quickly providing a competitive quote and getting us on the calendar in a matter of weeks. Richie and the installation crew were incredibly professional, courteous, and got the job done without delay. Would 100% recommend Genove for any heating/cooling service needs - they are a pleasure to work with!

Weston L.
We have been with Genove for 15 years, and their service is consistently exceptional. They are incredibly honest; in a volatile market, the owner personally calls to provide pricing insights so we can make informed decisions about our oil deliveries—without any pressure. Their rates are competitive, the maintenance team is thorough and attentive, and their customer service is top-notch. I truly wouldn’t trust our home to anyone else.

Jenn W.
2026 Update: Ritchie came out this morning to look at a combi boiler unit replacement and give quote. Gave me honest feedback about age and performance of unit which I appreciated! It’s rare to see honest brokers these days and I always feel that Genove is different because they care more about their service reputation and customer relationships vs other companies who are just out for a quick buck. Thanks again Genove and Ritchie! ——— I’ve been with Genove for a few years now and have no regrets. Their customer service--from techs to management is top notch and I had ZERO issues when they recently installed a beautiful new water heater for me. I would recommend their services to anyone who needs an expert in this field.
