HVAC reviews in Baltimore, Maryland

Really nice guys- great service and looks to be done well.

I got a water heater replaced. They explained everything that needed to be done to upgrade and make it safe (my old gas water heater’s exhaust was coming back into the house) Highly recommend.

They even came out once at around 9pm when I realized my AC wasn’t turning on. Kind of service you don’t get from a lot of companies

Hey people when I say excellence at its best I’m saying Cozy heating and cooling put it down. Jon and Monty put their experience, hard work and integrity into installing my new A/C & Heating unit. I can honestly say this experience was thee best experience I’ve ever had dealing with a contractor. They were determined, relentless , focused but also found a way to keep me informed every step of the way. I only wish every issue could be this pleasant. Thank you Jon and Monty. 10 toes down this is the best HVAC company you could ever have the pleasure to deal with. I was always told to make good choices, I definitely did today 💯

If I could rate 10 stars I would !! I had 3 quotes. They were the best due to what was being offered as far as safety with my electrical box, putting in a new return and overall customer service. Everything was installed today with top notch quality and correcting issues from my builder. They go above and beyond to ensure it’s accurate. I highly recommend this company!!!

Jon and his team were amazing. My heat pump died suddenly in late November, and not even the electric heat strips would work. It was Thursday a week before Thanksgiving, and Jon came out and gave me options on repair versus system replacement. I opted for replacement, and he worked hard to move quickly and fit me in on the day before Thanksgiving. He was friendly, professional, and was easy to reach and responded to my texts and phone calls. He showed me how to use the new system and took the time to answer my many questions. He did a fantastic job, and I will definitely reach out to him in the future. I would recommend him to anyone needing HVAC services in the area.

This was my first time using Cozy Heating & Cooling, and I originally found them online. From the initial contact to the final walkthrough, the entire experience was excellent. Their team was very professional, punctual, and knowledgeable. They took the time to explain the process, answered all my questions, and made sure everything was done correctly. The installation itself was smooth and efficient, and the quality of their work really shows. I’m very pleased with the results and would definitely recommend Cozy Heating & Cooling to anyone looking for reliable, high-quality service.

Cozy Heating & Cooling did an awesome job! Jon and Perry were excellent—prompt, professional, and very courteous throughout the entire visit. They showed up on time, explained everything clearly, and made the whole process easy and stress-free. Highly recommend them if you’re looking for reliable HVAC service!

Mr Scott came in for an emergency call on a Sunday morning. He could easily have taken a quick look at the system and then said he couldn't do anything until Monday when the manufacturer was available. Instead, he diligently and persistently looked for a way to get our heating system back online. His persistence paid off, and brought heat back into our house just before freezing night. Thank you Mr Scott

Courteous enough to explain what he did in my system and reasons behind why the AC not working properly.

Stephen did a great job period he was courteous, polite and professional. Very satisfied with his performance.

I highly recommend Stephen Scott from One Hour Heating and Air for HVAC technician services. He is extremely courteous, punctual and even phoned ahead to ensure our availability.

I always request Stephen for regular maintenance and any emergencies that may arise, as he is the reason why I continue to choose One Hour.

I used this company for a second opinion and estimate after being told by another company that I needed new HVAC system.
Stephen Scott came out same day request was made. Not only did he find out that I do not need a new system, he gave me three options that may extend the life of my air conditioner. Stephen was thorough, knowledgeable, patient, friendly, and kind. His customer service skills are unmatched. I will definitely consider using this company for future services and highly recommend Stephen Scott as the requested technician.

Mr. Stephen Scott is a life saver. We were without heat for days. He patiently walked my grandmother through the issues we were having with the furnace. Not only was he helpful, knowledgeable and courteous, but so kind to come back on his day off and complete the job.
