Welzig Heating & Air

My favorite part of using Welzig Heating and Air is I know they give a lot back to the local community. You not only get great service, but many people benefit because of their generous hearts. We were really blessed one cold night back in December when our heater went out and we desperately needed it fixed. They got our house warm and toasty quickly and I really appreciated it.

The appointment was requested for morning before 11am. The tech arrived at 3:15pm. Once on site, Weston (the tech) was very professional. He diagnosed the problem in 5 minutes, had the part to repair the AC condenser, tested the whole system and was out of there in 20 minutes. He wore shoe covers in the house and left everything tidy in his wake. They charged me $ 198 for the exact same part I can purchase at Home Depot for $ 98. Seems like an extreme markup. I’m not sure I will call them next time.

Casey and the team at Welzig have serviced my business for the past two years. Not only did they get our new furnace in ASAP, they gave me a great rate on the equipment they installed.
It was the start of last summer where our swap cooler died. Welzig came out again, replaced the cooler with a new central AC that was tied into the heater they replaced only a few months earlier. They patched the hole in the roof where the cooler was.
I have even had them come out and have them clean out the heat exchange in my pool boiler.
They are always friendly and I have never found a better price. Will continue to call Welzig for any HVAC issues.

During what was supposed to be a routine heater cleaning and adjustment service, the Welzig HVAC Tech used a fiber optic scope to visually inspect the heat exchanger and pointed out several metal surface irregularities that he said were cracks resulting in a CO leak which was not safe, and therefore the heat exchanger had to be replaced or the heater replaced. Welzig’s literature claims that not using an optical scope to inspect the heat exchanger «would be a disservice at the least and borderline fraud».
The Welzig Tech provide a quote that we could either replace the heat exchanger for $ 3,829 or buy a new Lennox heater for $ 3,419, but we had to make the decision in the next four days if we wanted to take advantage of the 20% year-​end Lennox discount. But, the Welzig Tech said we could continue running the heater during the winter cold snap we were experiencing as long as there was a CO monitor in the house, which there is. But this did not sound safe.
So as soon as the Welzig Tech left, I decided to get a 2^nd opinion and if necessary another quote. During which I learned that our Carrier Heater had a 20-​year warranty on the heat exchanger parts and it would only cost $ 400 in labor to replace the heat exchanger, if there was an actual CO leak.
The 2^nd firm made it clear that the only way to determine if there is an actual CO leak is to use a CO detector probe placed above the heater exhaust. They do not use an optical probe because it not reliable due to minor flaws in the metal surface.
I schedule the 2^nd firm to send out their HVAC Tech. During this inspection and with the heater turned on we watched his CO detector increase from 0 parts per million to 2 PPM which validated there was an actual CO leak. And as the heat exchanger ages metal fatigues due to heating and cooling will only get worse over time. A «serious» CO leak is greater than 50 PPM.
So instead of spending $ 3,829 to replace the heat exchanger with Welzig, we spent $ 400 in labor cost with the 2^nd company.
After several attempts to get the Welzig owner on the phone to discuss the problems and misrepresentations; he never returned the calls.
