They cam back out and reset the code but did not diagnose the cause. Soon after this visit the system went down again with same error code. Pipes froze and burst damaging wood floors, and now a new arrow code with the other one. The tech Lied about the system working when he arrived and said no error code was displayed. They refuse to take responsibility. Dishonest and incompetent company. I do not recommend this company.

Had furnace installed by them and when it quit working a few months later they came out and cleaned out the drain tube to the squirrel cage fan that got plugged up by their installation debris and water collected shorting out the circuit board. They charged me for their bad installation over $450 just to fix their errors. The guy they sent out, no fault of his, said it happens all the time where the lines get dirt from cutting them in the first place and they are in too much of a hurry to clean them upon installation so they come back and make even more later! Avoid 4 Seasons Cheating and Fooling Company! Rip offs!

Communication and consistency.

We put in a request through our home warranty to put ceiling fans in, was told to our faces we needed to tell the warranty company they did the work so they could get the funds for the fans (our mistake for doing so). Then proceeded to not hear back or get anything done for over half a year. Eventually went and asked for the fans to do the work ourselves or with someone else, and found out they got much cheaper fans than they were supposed to. We wanted so much to give the benefit of the doubt (only having one tech available is difficult I'm sure), but even with a whole crew of techs that wouldn't fix the lack of communication and the downright shady business practices. Horribly discouraged customer.

Absolutely horrendous. Started out friendly and nice, didn't actually fix anything. Instead they…read moreRUINED the control panel of our boiler heater. They used up our yearly allowance from the home warranty in multiple visits and never fixed the issue. It has been over a month now and they have been out 3 times. The control unit is broken beyond repair. Had to hire someone else to come fix what they broke. They will no longer answer the phone. When the home warranty tried to call them, they hung up on them. DO NOT DO BUSINESS with these people. You will not get what you pay for.
