Lets start by looking at the different models of Goodman gas furnace, and then cover warranty and quality of installation issues. Whats in a model Efficiency, blower motors, and everything else.

My personal recommendation for anyone considering buying a furnace is to go for a high efficiency model 9. Goodman gas furnace which is typically less costly than other brands. The high efficiency models achieve their peak efficiency in part by using a sealed combustion chamber with both intake air and exhaust gases vented to the outside through PVC pipes. By drawing in outdoor air for combustion these furnaces avoid sending already warmed indoor air outside. The heat exchangers in all models are a patented tubular design made of aluminized steel, and ensure that most of the heat produced from combustion goes into warming your indoor air instead of warming the outdoors via the exhaust. You know your furnace is efficient when it can send its exhaust out in a PVC pipe Remember that an 8. US or Canada must be at least 8. One often forgotten aspect of energy efficient furnaces is the impact on overall operating cost that the blower fan can have.

The high efficiency Goodman gas furnace models have an ECM motor Electronically Commutated Motor which is a brushless DC motor. These ECM motors offer a number of advantages. First, DC motors tend to be more efficient than their AC counterparts. Second, a brushless ECM motor doesnt have any brushes to wear out, so its durability is better. Finally, the DC motors on the high efficiency Goodman gas furnace support a continually variable speed, so that the blower motor can adjust precisely to the level of air circulation needed for your homes moment to moment heating needs. Choosing a Goodman furnace installer. Its easy to find consumer complaints against Goodman gas furnaces on user contributed review websites, but as I explained earlier this is a biased sample, since satisfied customers dont tend to write reviews of their furnaces. Youll find more complaints against Goodman than against competitors such as York, Trane, Bryant or Carrier Bryant and Carrier are made by the same company. On the other hand Goodman also gets more favorable reviews than those brands, and has a higher ratio of favorable to unfavorable than any brand but Trane. I really dont think a few disgruntled customers are enough to base your decision on, and I generally discourage people from reading owner submitted furnace reviews, because whatever brand you start with, youre likely to decide not to go with that brand based on the built in negative bias of online furnace reviews. Most furnaces are made of the same basic components, and in many cases those components are sourced by multiple furnace manufacturers from the same parts manufacturer. For example, most of the controller systems for modern furnaces are made by Emerson, a leading manufacturer of electrical components, while the gas control valve for Goodman and other furnaces is made by Honeywell.

As for the engineering and quality of the Goodman units, many of the pros believe Goodman gas furnaces are as well designed and as solidly built as other common brands that sell for substantially more. Instead, I think what is behind the reported problems with Goodman gas furnace quality is the result of a small percentage of installers lacking the skills or ethics to do a good job of sizing the customers system properly, installing it correctly, and providing the right annual maintenance. Goodman is a relatively new company for the HVAC industry. Its a privately held company founded in the mid 1. Compared to some of its more established competitors like Lennox founded 1. CarrierBryant with histories stretching back to the early 1. As a younger, privately held company they may have taken a few short cuts in recent years on one aspect of quality control the approval process for becoming a qualified Goodman installer. If you dont carefully screen the companies that are authorized installers of your product, youve essentially lost the quality battle, because that small percentage of unscrupulous installers that wouldnt have passed a more rigorous screening program will create a vocal minority of unhappy customers. Heres how I believe this plays out. Goodman is known for lower than average prices on its gas furnaces. Installers know that, for some homeowners or landlords or developers, low sticker price is the key decision factor. So they will start by suggesting an inexpensive furnace like a Goodman gas furnace, and then cut corners during the installation. The first corner they are likely to cut is doing a proper heat loss calculation for your home to determine what BTU capacity of furnace you need. In most cases, installers who just want to cut a quick deal will skip over the heat loss calculation entirely and may not even know how to do one, and will just eyeball it and tell you what BTU capacity you need based on gut feel for your house or for your pocket book.

Then when it comes time to install, theyll use lower quality components, may damage parts during installation, may hook things up incorrectly, and so on. Its possible, for example, to get the air intake and combustion exhaust pipes mixed up, so that the air intake is above the exhaust pipe on the outside wall, instead of below it Ive seen this done. If an installer does this, your furnace is drawing in air that contains less oxygen since some of it has been burnt previously, as well as combustion byproducts that are corrosive to metals, and your heat exchanger is likely to last five or ten years instead of twenty. And your warranty is void. Remember High quality costs more, once. Low quality costs less, again and again. Quality starts with the team you chooseOn the other hand, if you hire a company that has a solid five star reputation, you are off to a good start. First of all, make sure that as part of the quotation process you get a proper manual J calculation of your homes heating requirements, so that you get a system correctly sized to your home. Interview at least three different companies you can start on the phone, and then only bring to your home those who sound dependable enough to proceed to the next step and who are willing to do the heat loss calculation.
