Turns out the meter socket was corroded and the feeder line into the house needed replacement. Accurate was able to come out within hours, recognizing the urgency of the situation, and take care of everything for me. More impressive than that was service we received. Ziam was communicating via text messaging before he ever arrived. He worked hard in the hot sun. Once completed, he walked me through everything he had done and talked about things that should be on my radar in the future - our house is 75 years old, so it is in need of upgrades. And when he left, you would not have known he was ever here - left the place cleaner than he found it. I found Ziam to be empathetic and understanding as well as helpful. I can't say enough good things. You have a customer for life.

I had another company look at my system as it started acting up. They gave me me an estimate to…read morereplace the entire system and I said how much do I owe you for the visit and sent them on their way.... I called Alpha at the recommendation of my Auto mechanic shop. It was earlier in the day so I didn't hear from them for a few hours. I had called other places and they were too busy or not what I was looking for. It was going to reach 100° this week and today was Monday. I received a text from Scott, the owner saying he'd be reaching out soon. Shortly after we spoke on the phone and I told him the symptoms of my system which is an old Trane(it's hard to stop a Trane). Right away he knew what to look for and said he would make it tonight and I jokingly said "we're up until midnight"... Well sometimes after 7: 00 pm I got a text saying they are on their way. They showed up and with no hesitation. Went right to the system and started analyzing. They found what was wrong within a couple of minutes and immediately started to do the repair. I had my lady go inside and turn the AC on and boom the compressor kicked on as it should have which is the unit outside the house that was kicking on and off. No fuss, no muss and we are now getting deliciously cold air again! HECK YES I recommend this company.. Thank you Alpha Tech

Despite this he came all the way down to Branford at 9 PM just so we could be operational. Our motor was blown and he replaced it with a shiny new one right away. He could have not answered since it was end of day and he could have scheduled me after he returned or referred me to someone else but he didn't. He was responsive and upon meeting him, you could tell he cared. He also was very reasonably priced (and given the circumstance I fully anticipated it was going to cost me an arm and a leg)! Superior service! I will be using Scott for all my HVAC needs moving forward!

They made sure we understood how to use our units and if any questions arise, to give a call. Rain and thunderstorms were scheduled the next day, so they went above and beyond and stayed until the job was complete, 12 hours! I also want to add there was no mess to clean up! My husband and I were so impressed with this whole process! I highly recommend Bob Carlson and his crew. You won't be sorry! We're already inquring about our next project!

I thought they had a special tester. I was wrong about special tester. Ultimately I could have tested it. But the tech was detailed in his diagnoses and explanation and the Ignitor was replaced. Afterwards I found the price charged me was 3 times retail at H-D. I am a retired electrician. They tried to also sell me the controller that had no issue other than it was old. I said no... because I am an electrician, and I can swap that if needed, it's just a relay unit. Then realized after they quoted me 3 to 4 times retail $ on that item too. The techs are knowledgeable and appreciate their work, but their parts pricing is too much. I recommend them for their knowledge.

They were able to come out within two days, while every other company I contacted quoted two to three weeks just to get an appointment. The person I spoke with on the phone was incredibly kind and understanding. They kept me informed, called to let me know the technician was on the way, and even texted me a photo of the technician beforehand, which I really appreciated for safety and peace of mind. The technician who arrived was very nice, professional, and extremely helpful. The entire experience was smooth and stress-free. Since the visit, my furnace has been running quietly with no more strange noises. Best of all, the maintenance service was under $200, which felt very reasonable given the quick response and quality of service. I'm so grateful they were able to help on such short notice and would absolutely recommend them.

We had what I now learned from a non-local family friend was a simple backflow preventer failure. The friend ball parked it around $500-600 max, and that was with up to 2 hours of time taken. This company charged me $1300 for an hour of time with a single part being replaced. Similar parts are available online for $150 (and I assume they get parts even cheaper). My family is leaving town this weekend and I wanted to ensure this got fixed (but it was not an emergency call), so I didn't take time to vet out other contractors. I regret that, and have learned my lesson. Thanks F.F. Hitchcock. The Tech who visited was professional / explained things well. I'm not sure who sets the price, so if he had nothing to do with it, then this feedback should strictly go against F.F. Hitchcock's pricing structure. I reached out to F.F. Hitchcock a couple of hours after the service was performed, but so far have not received a response 2 days later. Do yourself a favor, find another company to service your plumbing / hvac.
