Best Way To Compare New AC and Heating Systems Before Buying

This blog describes how to cut through the “clutter and noise”, and buy a new furnace and AC system wisely.   I first learned this way of thinking while working my way through college in a bicycle shop, and there are some useful, current parallels to the way HVAC equipment and systems are sold.

More Brands Than Factories
Working in the bike shop, I learned that there are a lot more bicycle brands than there are bicycle factories.  Same (or very similar) bicycles…different label, marketing and prices.  Bicycles have a frame onto which major and minor components, made by other manufacturers around the world, are added.  These are combined in a box at the bike frame factory, sold through distributors, and must be assembled by a trained mechanic at a shop to be warranted.

With air conditioners and furnaces, the frame is a box, usually made sheet metal. With a few exceptions, the main components, such as compressors, condensers, fans, coils, heat exchangers, come from factories around the world. As in the bicycle brand example, there are fewer AC and heating component factories than there are brands.  Parts do come in differing grades of quality and efficiency, and the cost (and sometimes the complexity) usually goes higher with the efficiency rating.

There are some generalities about HVAC equipment brands that may be worth knowing. However, before thinking about brand there are two more important aspects a buyer needs to focus on:

Needs Local Professional Assembly or Installation

For safety and efficiency, we mechanics often had to true the bike wheels, and adjust the gears & brakes.  Then we adjusted parts to the needs of the rider, and added accessories based on the conditions the rider would encounter.  If we goofed up, the bike would not ride efficiently or the rider could crash and get hurt.

With AC and heating equipment, the installation is a critical factor. Some types of mistakes are very difficult to correct.  First, the local company that installs your equipment should have helped you choose the size and efficiency specifications appropriate for your climate, envelope (the part of your house or building that interacts with the outside air), and budget. Next, the installers have to be skilled in plumbing, electrical, refrigeration and more to connect the wiring, piping and refrigerant to make the equipment run safely and efficiently. Also, if your existing ductwork is used, they must make sure it is in good condition and sealed.  Should the wrong size or type of equipment get installed into your home or building, it will be a major hassle making things right.

Assure Quality of Installation First, Then Compare Features For Cost
In summary, here are the action points to make a wise heating and AC system purchase. Each one has links for more details if you need them:

1- Choose a local service company with trained and experienced installers and technicians.  Go to this page to get more info on how to make a good choice.

2- Verify that you are getting the correct type and size of equipment for your climate, structure, and circumstances. More info here

3- Use our free cost comparison grid to compare the most important features.

4- After you have done this, you can see how brand fits into the picture.

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.
