Buyer’s Guide To Heating and Air Conditioning Says “HVAC Equipment Brands Are Less Important Than Quality of Installation”

We frequently get asked this question:

“Why would a buyer’s guide not list equipment by brands, models and features so we can compare them?”

A blog is a great forum in which to explain this. For easier reading and response, we will answer in a top 5 list:

1. The brand that is on the new equipment matters much less than correct installation.  It is often stated among insiders that a good HVAC technician can make lousy equipment heat or cool OK, while a poorly trained or inexperienced technician might not make the best equipment in the world heat or cool reliably or efficiently.  We’re not saying cut corners on the equipment¬—we are saying focus first on the training and experience of the company and employees who will install your equipment. Then let them explain which types of equipment you should consider. Remember, these are also the folks who will provide maintenance or warranty work on your system.

2. Heating and A/C systems are made up of components that can be mixed and matched, yet contain some common elements, such as air handlers. Rating new equipment either by brand or piece by piece like TV sets is not very useful. Just because two pieces of equipment will physically fit or function together does not make doing so a good idea for optimum results, however.  It is true that a manufacturer’s suggestion of equipment models to be matched is preferred over a “field match”. 

3. Some of the mixing and matching of components can involve existing equipment, such as your ductwork. Unless there is new construction or a total system replacement involved, some existing equipment may be used. Here we get back to quality of installation and the integrity of the installer. If your existing ductwork is used and it has an interior problem (such as mold or contamination) or unsealed leaks, then comparisons of equipment features such as efficiency are much less relevant.  Look out for low bids that cut corners on ductwork, old inadequate wiring or other use of existing equipment.

4. Once must consider features and specifications listed by manufacturers or even independent testing organizations, as they relate to conditions and the envelope of the structure where it will be installed. 

5. There are more brands of equipment than manufacturers of components.  Therefore, some brands share common internal parts.  As an example, look at the common ownership among the brands listed on the lower part of this page . Out of ten major brands, depending on how they are counted, there are about six companies who control them.

As a quick recap, points 2,3, and 4 above reinforce point #1: the integrity of the installation will affect your overall satisfaction and comfort more than the brand of equipment.  A quality HVAC service company will guide you on your equipment options and then install them correctly.  However you go about making your comparisons, start with the quality of the installer first. Then compare features and benefits of the equipment.  You can use our free comparison grid to help.
