"Excellent service by MarKool. First it is a small company so when you call them you talk directly to the person doing the work. Second they are highly responsive. Third at the home they are very personable and answer all questions in detail. Fourth In fixing my problem they showed they are highly skilled and experienced in HVAC in this case as it pertains to gas furnace operation."

"Great company! They've been super responsive when we've had questions or concerns, and deliveries are frequent enough that we never have to worry about running out of heating oil."

"The Service Technician was very professional and explained things. I signed a service agreement with the company for our two-zone system. So far so good. Our furnaces were serviced."

"Sean was great during his visit to fix our furnace. He met us right away on a weekend, knew exactly what was wrong and repaired it for a very reasonable price. He was so good we asked him on the spot to do our twice a year furnace/AC checkups. Can’t recommend him highly enough."

"I am happy to write this review about JDL HVAC Services LLC. From start to finish; Amber, who setup my initial appointment was very nice & professional. Ire, the technical associate was prompt, very knowledgeable and got my system working again with a temporary fix. I opted for a new heating unit (which was reasonably priced) and all of the technical associates were easy-going and very professional. They were organized, used protective foot coverings and protective coverings for my floors, and cleaned up after the job. Special thanks to the entire team led by Armando; Jerel, Fernando, Michael, & Conrad. NOW, thanks to JDL HVAC, I FINALLY have a properly installed & functioning heating/air conditioning unit. I highly recommend this company!"

"I had a high efficacy heat pump system installed by ARS 11/2 ago. I am used to gas furnace so understanding how heat pump works is an education. The mechanic was very patient in explaining how it works and what to look for if there is an issue. Of course this cold season a got an high unexpected bill from the electric company and was baffled because of the amount I spent on this high efficiency unit. They came out looked at and found no issue. They explained this was a very unusual cold season and the unit performed accordingly for sub freezing condition. They did leave a card and said if I see anytjing that look unusual please give them a call asap. The mechanic was very knowledgeable."

"I hired Ward Services to replace my AC and furnace in 2023, then again in 2026 for my new home, as well as regular maintenance and system check up since 2023. Their service is consistently professional, and the cost is reasonable comparing to the estimates by some big HVAC companies. The lead technician always takes time to explain in detail the existing problems and options. Highly recommended."

"All went very well! They were very responsive to my inquiry. I had anticipated a few days before anyone would come out due to the heatwave we were experiencing, however, to my surprise they came out the very next day as promised. I even had asked for them to install a replacement thermostat which they did as well."

"Unlike other vendors, Adam was straightforward and provided honest assessment without complications and excuses, which initially made me suspected if he was for real. Fortunately I selected Weather Masters for their professional installation of 3 heating/cooling systems. I'd recommend them to any other customers."

"Easy to make an appointment. Very professional work. Courteous and knowledgeable. Willing to explain everything. I will recommend this company to anyone I know. When I update my aging furnace, this will be the first company I call."
