I initially thought about taking off a star because John arrived outside of my appointment window,…read morea pet peeve of mine, but then I remembered a few things: he came on a Sunday, on less than a day's notice, Arlington is very far from Upper Marlboro, the appointment before me went over, which can happen to anyone, and most importantly, small businesses are the backbone of America. John was very polite and immediately told me my HVAC closet smelled because a mouse died in there. He also called a relative while at my place and on the way home to give me their suggestions on dealing with the smell, which has nothing to do with HVAC and is above and beyond in my opinion. Yes, I did have to pay the $100 fee to come out. I paid in cash to not have to pay the 10% processing fee. I was fine with paying this to have someone come out so quickly, and on a Sunday. Would call again. When my problem actually involves HVAC repair.

I'm a certified home inspector and Nestor installed my new AC and Furnace correctly. It was a BIG…read morejob. I trusted them to completely replace our system, and they did it quickly, efficiently and at a good price. And Nestor had followed up on multiple requests I had to make a couple of adjustments so that our new system was running perfectly. It's 95F today and our new Bryant AC is running COLD air and holds it's own. I got estimates from multiple providers who wanted to rip me off because my furnace was broken on the coldest day of the year. Nestor gave me an honest quote and didn't give me excuses like "I need to do extra sheet metal work" or "your system needs a new flue". He figured out what was the best midrange furnace and AC for our house and quickly installed it so our house wouldn't freeze up. His installation was up to code. The Nest thermostat didn't work at first but when I mentioned it wasn't working, he came back the next day and fixed it. The aC and furnace he installed are quiet and energy efficient. He also installed a high quality air filter. I looked for leaks in his duct work and I couldn't find any. He correctly set up the condensate drip line to extend 1 feet past the foundation of the home. I do wish he put a more sturdy mat for my aC, time will tell if it shifts and he has promised to come back if I need any adjustments.

They cleaned it out and it worked for a year. Then it failed entirely and they gave me prompt emergency help despite it being the weekend. I had them replace it with a new heat pump version. Nestor gave me great knowledgeable advice about the options and how to navigate the 2025 change in the refrigerant regulations. Very competent and very competitive rates!

I called and left a message with a different HVAC company I've used in the past and I still haven't heard back from them.

Zack was very nice and was careful to explain everything. It ended up being a $160 capacitor and we now have cold air cranking. Thank you Cornett & Zack!!

That was also the exact price we paid upon completion. Quality brand, not the builder grade stuff two others were giving estimates on using, and Fixed HVAC beat both their prices by over $1k with no back and forth! I've used them for routine maintenance over the last several years also. On time, clean and professional. We built one home and did extensive renovations/additions to three others. We are not rookies at hiring tradesmen. This is a local Annapolis outfit that deserves a shot at your business. Not kidding.

I had Bethany Air put in a new SMART thermostat in end November 2024. They were here 2-3 hours…read moretrying to get it to connect. They left with the SMART thermostat functioning but disconnected from the WiFi. I was finally able to connect it a couple days later to the WiFi. A few months later (April) I called the thermostat manufacturer due to an issue with my 4 year old furnace and the thermostat. I asked why it kept running my emergency heat more than my regular heat and my house was cold. They ran through troubleshooting with me and figured out that the thermostat was not wired correctly. The thermostat manufacturer stated the incorrect wiring caused the issue with the emergency heat running frequently. They suggested calling a HVAC repair to address the cold house. I called Bethany Air. The technician (1) came. He told me that I needed a transformer after spending a good 50 minutes in my attic and then assessing the heat pump. I asked about a surge protector and he also thought this a good idea. Both items were ordered. Other information was provided that possibly we had a power surge that caused the transformer to stop working in the furnace. I was also told the furnace would not run. The technician was here a long time. A different technician (2) came to put in the two parts a few days later. He went in the attic and came down about 5 minutes later and asked if we had turned on the heat. I stated no, it doesn't work, and I had not messed with the thermostat. I did note it was on though as the previous technician gave no recommendation to turn it off. He stated that a couple other parts had "burnt" and we "were lucky that the house didn't burn down". We discussed briefly the findings. I informed him that we were told the furnace wouldn't work. The previous technician (1) did not give any instruction to turn off the thermostat, to turn the breaker off to the furnace or heat pump, nor did he take any precautions to avoid this further damage (burnt parts) from happening. I called Bethany Air when he left. The receptionist took the information than stated the manager/owner would call me back soon. No callback was received from the manager/owner. Instead the technician (2) who had left called me and tried to change his initial assessment and downplay his findings significantly. The parts came in and a different technician (3) came. He made the repairs. He told my husband that all charges for all 3 calls would be in his invoice. I paid the invoice. Since then I have received an invoice a couple times after I paid the "all charges" invoice. We have reached out to the company 3 different days, speaking with the same receptionist. We are told the owner/manager will call us back that day, and have never received any callback. Email response to the invoice also got no response. I cannot recommend this company in good faith. However based upon other reviews, you may have a better experience.
