Product Reviews:

Heil air conditioners are durable because most of them are made of galvaniz
Heil air conditioners are durable because most of them are made of galvanized steel. Heil offers air conditioner unit for any price range that one can manage to pay for. The company has manufactured rather cheap yet unfailing solutions for all their customers. This is convenient especially for consumers who desire comfort but their budget and purchasing power is a bit low. Also the warranty terms of Heil are reasonable and much favorable as compared to warranties from other brands in the market. This is helpful especially to consumers buying the top notch Heil’s air conditioners.

Heil is not that famous in the heating and cooling market. People know Trane, Carrier, Goodman but seldom talking about Heil, Day and Night which actually are from the same company of Carrier. Heil rarely do any marketing promotion and that’s why the Heil’s price is lower. If you can choose a good contractor to do a qualified installation, it can runs normally for 10-20 years. Finding a trusted installation contractor with rarely promoted brands is always a good choice.

Complete system was delivered and installed in about 6 hours and does a good job of controlling our home climate. Can’t provide efficiently related to our energy cost because it was only installed to replace our old 24 year old worn out builders grade system this past weekend.

When I moved in to this new house one of the first things I changed was the air conditioning. The I found here was not working right so the cooling couldn’t go below 770. Now I have Heil and everything is working perfect. It’s been 7 months since I got it and so far am pleased with its functionality. It hasn’t given me any headaches. I read reviews about the air conditioner breaking down or malfunctioning in some way after 3 months. I guess I got a sweet deal from Heil.
