We hired this company to install Mitsubishi Split Ductless air conditioners. The units in the…read morekitchen, den, and guest room worked beautifully. The unit in the master bedroom was problematic from the start. The bedroom would not cool off. We wound up putting in a window unit while we waited for them to return. The master bedroom unit was the furthest from the original condenser, and we think that the length of the piping was not efficient and that is why the room would not cool off. They installed a separate condenser just for the bedroom. (Generating 2 separate fees every year for maintenance) Periodically, the unit would tick so loudly it would wake us up. They came back out, of course we could not re-create the issue, but they didn't even bother to take a detailed look at the unit to see what was going on in with the bedroom unit. The tech got nasty with me, and was very condescending. When we called them to schedule the yearly maintenance we were told they were out of business. We hired another company who came out. The tech took the unit apart, cleaned it put it back and the unit stopped ticking. All the technician did was clean the unit and snapped everything back into place.

They even talked to me about prices and while they were willing to come out, advised me to try to wait until morning as it would cost me at least $100 less if I could wait. When they did not hear back from me, they called me again at 7:30 the next morning to see if I still needed someone to come out! We ended up going with someone who specializes in our particular boiler, but I would have gone with Airtemps if we hadn't found them. Great customer service!!

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

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!

I had this company perform the regular maintenance and cleaning of my two oil burning furnaces and…read moreone oil burning hot water heater on October 22, 2025 at a cost of more than $500. On January 30, 2026 I had an oil tank service company inspect my system where there found a drip coming from one of the oil burners. There was no "active" dripping indicating that it was a very, very slow drip that had soaked the absorption pad placed under the burner by the J.P.Parks service technician three months earlier. After contacting J.P.Parks regarding this, their response was less than satisfactory, blaming me for not regularly inspecting their work for proper performance, and telling me that there would be a $160 charge for them to correct the leak. (See text message screenshots). Apparently, if this company is used, the customer is responsible for assuring the work has been properly performed, and is responsible and liable if it has not. This company also scheduled an oil tank service appointment with me and then blew me off with no explanation in the middle of the worst weeklong cold snap we've had in years. UPDATE: 1/31/26. So I had to have another company come to service the burner to fix the leak. The technician showed me the "gun" which is where oil is atomized for ignition, and is the most important part that needs to be properly cleaned when maintenance is oerformed. The technician states that this piece was not properly serviced three months ago as it is caked with dirt accumulated over a much longer period of time. (See photo)
