Air Tech Heating and Air Conditioning Inc Rated 4.52 out of 5 stars based on 33 customer reviews

We were recently called in by a customer whose air conditioner was refusing to blow any cold air. After thoroughly examining the system, our trusty technician found it was dishearteningly low on refrigerant. The culprit? A sneaky leak hidden right in the middle of the condenser coil. But, no problem is too big or small for us – we quickly repaired the leak and refilled the system with a little bit of our very limited supply of R-22 refrigerant. After a successful test run of the air conditioner, we left the customer with a cool and comfortable home again. We're always happy to help and greatly appreciate their business! 🙂

We had a wonderful opportunity today. A client presented us with a request to install two new mini-split systems. Feeling the warmth and wanting to give them the comfort they deserve, it was our pleasure to provide them with the ideal solution. We swiftly installed two Bryant mini-split systems, specifically, a 40MCCAQ18XA3 wall unit and a Bryant 38MARBQ209AA3 heat pump. We didn't stop there, of course, checking the operation of the system to ensure everything's working perfectly. We had a great day meeting a need and providing a comfortable solution! We thank you for your business! 🙂

Our handy team took a trip to Wright, WY, after a call about an underperforming ice bunker. We discovered the issue lay in the compressor and door gaskets, which were not in the best shape. So, we brought the ice bunker back to our shop for repair. Here, a new compressor was installed. We also ensured the system was properly evacuated and charged up with 2 lbs. of R-134a. Plus, we replaced a defective fan motor and filter drier. Delighted to report that another job has been successfully completed! We appreciate your business. 🙂

A customer reached out to us because their commercial freezer was giving them real problems - the thing wasn't getting cold enough. Not something you can ignore. So, we answered the call and headed over there. Upon arrival, we found that the freezer was hanging out at an unacceptable 9 degrees. We rolled up our sleeves and got to work! First, we inspected the condenser which - you guessed it - was plugged in the center. We cleared that up using our trusted CO2 to blow it out. We also checked all the fans and put the freezer through a test run. Would you believe it, the coil temperature dropped to a textbook -15 degrees. It was like the freezer had a new lease on life We appreciate the business! 🙂

A customer reached out recently to help improve the air circulation in a home that was having a bit of trouble with its basement bedrooms. Summer heat can be harsh and they wanted to make sure everyone stayed comfortable. So, we came in, assessed their needs and decided the best solution was to install return air transfer grills and sidewall registers to increase the air flow in their basement.The setup has greatly increased the airflow in those previously stuffy rooms and the customer is quite content. We love making homes more comfortable, one job at a time! We appreciate your business! 🙂

We were recently contacted by a customer who needed a recharge on her air conditioner. Upon our initial inspection, we found a loose liquid Schrader valve, which we immediately tightened, and also discovered that the plug on the blower motor had melted. Not a problem for us - we quickly rewired the plug and gave it a test run. We noticed a faulty capacitor, so we replaced it using a Titan Pro 10 mfd capacitor. On top of that, we found a poorly connected G wire so we made a fresh connection. We ran a second test, then checked the pressure on the condenser which was all good. Everything is now up and running smoothly for our customer's comfort! We thank you for your business! 🙂

Today we helped a customer who was feeling the heat with a air conditioning system issue. They called us in a bit of a sweat, as their air conditioner was not blowing any cool air. We dispatched our reliable A/C technician right away. After a quick diagnosis, we found the culprit - a faulty capacitor. We jumped right into action, replacing the problematic part with a Titan Pro 50+5 Mfd capacitor. Not wanting to leave things half-cooled, we test ran the system to ensure everything was up and running smoothly. We’re glad we could lend a hand and bring some cool relief to our customer! Thank you for your business! 🙂

Our team received a distress call about a malfunctioning A/C. We jumped into action to analyze the situation. We found that the problem was tied to a faulty capacitor. Without a second thought, we replaced the 45+5 mfd capacitor and the A/C started humming back to life. We didn't stop there though; we took the time to rinse out the outdoor condenser, sweep away debris from the indoor unit, and we ensured the whole system was cooling efficiently. Another job well done for us and a relief for the homeowner. Now, they can enjoy a cool indoor environment. No task too big or too small, all in a day's work for us. We truly thank you for your business! ☺

We were contacted by a customer who was experiencing issues with their HVAC system not working. Our experience has taught us that the culprit behind such problems can often be a faulty contactor, which was exactly the case here. So, we replaced it and noticed that there were also 2 bad overload fuses. We fixed those too, and then tested the system to ensure everything was running smoothly. The particular products we used to solve this problem were a new contactor and a couple of 3-amp fuses. Job well done, and another satisfied customer to our list.

We recently had a customer call in distress because their air conditioner wasn't working. Not a pleasant situation, especially during the heat of summer. Our savvy technician quickly identified the root of the problem - a bad capacitor. We swiftly replaced the faulty part using a top-quality 45+5 mfd capacitor. Of course, we didn't stop there. We made sure the compressor was functioning properly post-fix. It's all in a day's work for us, ensuring our customers can keep cool and comfortable.

We appreciate your business! 🙂
