Scheduled for inspections for the two forced air heating units on our property. They got me into the schedule for the very next morning. The service technician Doug was very friendly and walked me though everything he did in detail.

These guys are top notch. Great quality work, timely, courteous, and overall great to work with. Special thanks to Anthony, Alvaro, and Demarco who stayed late each night to make sure the job was completed with special attention to detail.

They have $ 89.00 service charge fee for just coming out to diagnose the problem. I was unable to get even a ballpark estimate on thermostat installation.

My landlord called this company to tell them my furnace wasn’t working and the company called me immediately that night even though it was after 5. they said they’d have someone out first thing in the morning which was GREAT! the next morning a repairman named Ninef came and he was really helpful. Very nice, courteous and took the time to explain the furnace problems. He got it working then called my landlord immediately and gave him options on what to do next (fix vs install a new system).
Overall, this was an excellent experience. You need someone quick when it’s cold and your heat goes out – this company was right on top of it. I recommend requesting Ninef as your repairman – he was super!

I want to express my appreciation for this company. They are very professional and very helpful. I had a young gentleman by the name of Jason come fix my heater for god knows i am freezing my fanny off. He was adorably nice, as when i offered him any refreshments for his sweat, he politely declined and went on to explain the problem with my heater. He was very passionate about his job and seemed to have a lot of information. I hope i do not encounter any problems in the near future, but if i do i hope sure to get the same assistant that i received or maybe even with Jason again.
Very satisfied :))

If I was rating One Hour Heating and Air Conditioning just on the punctuality, politeness, cleanliness, and friendliness of their technicians, or on their commitment to «making things right,» then I’d be giving them 5 stars. Unfortunately, however, my process from start to finish with them had enough bumps in the road that I need to downgrade my rating.
I ended up with the 2 heating systems in my building (homeowner unit and rental unit) being cleaned, AeroSealed, and working, and the price was quite reasonable. I had 4 visits from One Hour Heating and Air Conditioning in 3.5 weeks: #1 — complimentary heater cleaning and tune-​up. (This annual service was offered as part of the Home Protection Club membership we had recently purchased through Benjamin Franklin Plumbing, an affiliated company.) #2 — AeroSeal process to seal ductwork for improved efficiency and to reduce dust. #3 — troubleshooting «no heat» in both heaters (they considered it a warranty visit, done at no charge). #4 — Follow up to AeroSeal for duct cleaning (cost included in my AeroSeal quote).
On the MINUS side: I had 3 instances of technicians finding things that needed to be corrected that the previous one probably should have caught before leaving, a rescheduled appointment because of One Hour’s equipment being down, a couple of cool days with no heat because there was no technician available to come for 2 days, and a scary experience of my living room temporarily filling with smoke as the result of a technician oversight. This was all inconvenient, and in one case it was sloppy at best and dangerous at worst.
On the PLUS side: technicians I dealt with (Jason, Anthony, Kyle, Dennis) were all extremely polite, neat, and a pleasure to work with; supervisors responded quickly to calls from the technicians when there was a question; absolutely no high-​pressure sales pitch for additional services; twice the technicians called the office regarding money (for a quote and later when I paid with a credit card) and both times they put the office on speaker phone so I could hear for myself all the details about the costs; gave me a complimentary new thermostat when troubleshooting revealed that the old one was not working properly; honored the services, price and discounts quoted even though the subsequent technician said that they usually charged much more than the price I was told (no quibbling about it at all, just basically wondering out loud how I got «all that» included in the price), office called ahead of technicians’ arrival to give a more specific time estimate, 2 technicians gave me their direct phone numbers so that I could call if I had any questions. I really appreciated all these things.
I would use them again, despite the problems, because they were a pleasure to work with and did not charge me for anything beyond what I was quoted for the AeroSeal even though there ended up being a number of «extras» required to get everything working properly. I now know that I need to ask every tech to show me what they’ve done when they work on the system and to have them run it all before they leave.

ONE-​HOUR arrived June 8, 2015 to fix our 13 year old unit as it seemed to be out of freon. To find the leak was a fixed package rate (from their standard pricing sheet) of $ 885 for a leak search plus $ 1300 for freon. After verifying it was out of freon, they recommended the package price of $ 2,185 to add freon or $ 6,983 replacement unit. So now the comparison is $ 2,185 vs a new unit for $ 6,983. ONE HOUR had one goal, sell a new unit. I was not satisfied with the inspection and said it looks like a real diagnoses by locating the leak needs to be made before an intelligent decision about repairing vs replacement. Replacing could still end up being a good choice, but I did not seen anything to support that yet. Being out of Freon is not a diagnosis. I paid the service call fee of $ 60 (not sure of exact amount) and sent ONE HOUR home. I called another AC company and they added freon for $ 300 and the old AC unit has worked fine since. I absolutely would NOT recommend ONE HOUR. I’m baffled by how many reviews show as five stars as this is a bad company. Keep them out of your wallet.

One Hour Heating and Air Conditioning came to our rescue! They literally were here within an hour after we called them. Todd and his associate arrived, figured out the problem and had the AC unit running in no time. He was thoughtful enough to check the air filter for us before he left, which was in bad condition. They were quick, courteous, and knowledgable!

100 degree days are here and our A/​C was not performing up to speed. I called One Hour and was very pleased with the service, from the call center to our technician, Todd.
Todd, your professionalism and patience were very much appreciated. Thank you for your service, your politeness, and for not pressuring me to immediately decide on what needs to be done with our A/​C. I will definitely be calling back!

Excellent service from Jason R today. Exactly what I’d expect from a 5-​star HVAC company: prompt, fast and accurate diagnosis, fast repair and excellent advice with a very relaxed and communicative approach. I’d definitely call these guys for future needs.

Todd came over to help fix our non working AC. He was able to trouble shoot it and got it working for now. He was awesome! Then Ron came over within 15 minutes to discuss replacement costs which might be necessary. Both very professional guys and were awesome to work with. Definitely recommend them…

I had Todd came in and did the house inspections for me. He did the job very well, found a few problems with the furnace, along with the Thermostat. Told me exactly what I needed to take care of the issues. I bought the thermostat and he installed for me for free.
He is nice, funny, interesting. And besides the good job he’s done, he will make good friends with you

I’m sharing my experience with you of One Hour Heating & Air Conditioning. They called me early summer as part of a «Home Protection Club» package I bought from Benjamin Franklin plumbing. That package has heating and AC service by One Hour Heating & AC.
TODD came out to my property for the ‘tune-​up’. TODD said we had a cracked coil unit and quoted me $ 2500 to replace the ‘EVAP Coil’, and said I had a leak. (There was no known leak before he came.) TODD changed the air filter *with the wrong size* and left!
I had my home warranty send someone out for $ 60. Turns out my coil unit is fine — they were the ones that caught the incorrect filter size was installed by One Hour Heating & Air. My issue was a clogged line — something the One Hour Heating & AC folks — TODD — never even bothered to check. TODD did NOT walk outside to the drain to check if it was dripping. TODD did not blow in the drain line either. TODD didn’t even remove the panel to see if indeed the coils were cracked/​leaking!
I filed a compliant with the state licensed board. The owner called us and defended Todd’s work every step of the way. One Hour Heating & AC did not respond timely to the license board and I understand are being issued a citation. I cannot recommend more heavily AGAINST using One Hour Heating & Air.

My ac was out all weekend during the high temp. I called One Hour. Unfortunately they were not able to come out until Monday, they did come an hour earlier than expected for my scheduled appt. Brian P. was friendly, informative and fast. He provided helpful information and walked me through everything he was doing and why. I feel great about my choice to use One Hour. Their club program saved me enough money that it practically paid for the membership in one visit. Looking forward to my maintenance visits. Thank you, Brian. I am pleased with my service today.

After having my air conditioning inoperable for two days in 90+ heat I saw one of their vans in the area, called and they were here within an hour! Brian P. was the technician they sent and I couldn’t be happier. He was kind, professional and quick! Though my problem wasn’t large he offered me some tips in the future, made sure I understood everything, wore booties inside and even made friends with my dog. Very personable, would highly recommend!
