Recent Review: The experience was great overall. The technicians were good with explaining things at our level, since the equipment was new to us. They were incredibly patient and made sure that we understood everything. We were actually dealing with another contractor for the geothermal system, but that wasn’t such a good experience. Airtech stepped up and took over. Even after the unit was installed, they are still willing to answer any questions or help if needed.
The initial bid was not very informative. Their competitors gave a much better bid with bid packet and were all better at informing me about the facets of installing geothermal. I took the information from the other bids and picked Superior Mechanical because they were five thousand dollars cheaper. I should have gone back when I was suspicious of the fact that Superior wanted to install an eighty gallon water heater in a house with one person in it. I had that taken off the bid but didn't go back to research any of the other charges. There was never an itemized invoice of work order. I assume it would come at the end of the job but the invoices kept getting more and more vague. This includes a box of filters that were left that the competition said was 250.00. Two months after installation, The heat went out because they wired the thermostat wrong. That month my electric bill was the same as the year before but now I had the payment of the new system as well. The advertisement of the unit as being quiet was a fantasy as well. I can hear every change in the system while it's working. The next month the electric bill was higher so I called out the electric company to make sure they didn't have something wrong, but they said everything was ok on their side. I called the manufacturer who informed me that the unit shouldn't be using that much electricity and that the unit installed was too large for the square footage that I had. Superior kept saying it was not their fault. It was only when they sent out an electrician that they told me unless I had a well insulated house with good windows that the unit would only work as well as an electric furnace. Another point the salesman forgot to point out with all of the energy saving virtues of this unit. The final word from Superior, "Well , at least you don't have to buy propane". Yes, but I have a 200.00 monthly payment for the next twenty years. Lastly, when it comes to the rebate forms, It's six months later and I'm still trying to get the paperwork right and send it in since they DON"T do it as they said in the sale pitch. So here I am with a monster furnace in my basement that can't be returned that sucks in electricity like it was free and sounds like someone left a semi truck running. The extra humidity- oh, not in a house that's not airtight. Did I forgot to mention that. Beware and do a lot of homework. I would have gone solar first if I knew then what I know now. So much for energy savings.

I felt that the cost was well worth the service. He pointed out the good and the bad parts of the system. He came out when he was supposed to and gave me a good report on it.
