Check your paperwork before you agree to purchase. When I was shopping for a Geothermal installer I had narrowed it down to Covenant Heating and Cooling and another local company. Everything was close except; the other company was offering a 20-year warranty for their Geo system. The salesman from CHC told me that he would throw in the 20-year warranty if I went with them. (The extended warranty was available by the Bosche at an additional fee) and CHC said they would pay for the upgrade. At the same time, we also had an internet accessible Honeywell thermostat, Honeywell electronic air cleaner and a Carrier humidifier installed. After the first year we had the annual maintenance performed. That was when we discovered that the air cleaner was obsolete and filters were only offered by a third party. The 3rd party filters don't seem to be working, (due to excess dust on the furniture). Recently the outside sensor for the thermostat started eating batteries. The first batteries lasted for more than 4-years. The new lithium ion batteries since then only last about a month. I contacted Honeywell and they said the installer would need to contact them since they installed the unit. Although Honeywell has a 5-year warranty, CHC does not honor the warranty. They only warranty it for 1 year. With all of this, I thought I should check to ensure that I have the 20-year warranty that I was told that I was going to receive. Surprise.... they have no record of the offer by the salesman.
Lesson learned: no matter how nice the salesman seems, make sure you get it in writing and although the manufacture has a good warranty, make sure your installer backs the warranty. read more
