There are so many different types of gas furnace out there that it can be overwhelming trying to decide on the right one. Often gas furnace reviews only make matters worse as there are usually as many people saying a furnace is bad as saying it is good.
Before looking through gas furnace reviews, keep in mind a few key points. A vast proportion of problems with furnaces are not due to the manufacturer but can be traced back to bad installation or repairmen who don’t really know what they’re doing.
If you are reading reviews that complain that they have had a part replaced many times, it is entirely possible this person is being taken for a ride by the tradespeople they are using and not the furnace company.
Moreover if a reviewer complains about noise, leaking or poor heating it could be they bought the wrong size unit and/or the installation was not done properly.
However, it is not always human error or ignorance that results in a complaint. If there are numerous reviews citing time and again the same problem, such as noise or it not igniting, then this could be a design fault.
After examining various reviews, Tempstar, Carrier and Trane came out on top for reliability and efficiency. York furnaces were frequently criticized for being noisy, as was Rheem.
A common complaint for a number of companies, which is concerning, is poor customer service. Hopefully you will not ever need to contact the manufacturer directly, but if you do it is nice to know that your problem will be handled well.
Judging from the reviews, both York and Tempstar have a reputation for rudeness and bad customer relations.
Another thing to keep in mind is that you will always find bad reviews of any product. People are less likely to report a well-functioning furnace, whereas when people are frustrated or angry, writing a negative review is an excellent way of venting.
Ultimately it is best to keep an open mind about the majority of gas furnace reviews and seek the opinion of an impartial professional.
