Lately we have been receiving calls from customers asking what that big thing is in their neighbor’s backyard. There used to be a cute little air conditioning unit (which made quite a racket when it ran) but that’s gone and there is this new big box unit of some sort out there.” What’s going on?” They ask.

Let me explain what has happened in the heating and air conditioning industry over the past few years. We have had a tremendous amount of change within the industry.

First the efficiency of both the furnaces and air conditioners have had a substantial increase. So what has happened, you ask? The furnaces actually have decreased in size with most of them less than three and half feet tall. They have new types of components such as an additional heat exchanger to capture more of the heat for your home rather than it going out the flue pipe. The blower motors are a much newer technology which run quieter and use far less energy than the older motors. Just like your car, the controls to operate the furnace are more complicated and require much more knowledge on the technician’s side and computers (circuit boards) run the furnace for even more safety and energy savings.

Let’s move on to that big box in Joe’s backyard. Believe it or not that is Joe’s new air conditioning unit. Often the units are 50 – 100% larger than the older unit it replaced. If you went into Joe’s home and looked at his furnace and ductwork you would see that the inside portion of the air conditioning system (the indoor coil) is also much larger than the old one. There are several reasons for this. First the new efficiency standards cause the physical size of the units to be much larger. Next because of increasing electrical costs many homeowners are electing to install units with even greater efficiency to reduce the electrical operating costs. So the unit grows larger. An additional reason is in the phase out of the long used refrigerant, R-22, and the introduction of the refrigerant (R-410A) which has replaced it. It also contributes to increase in side of an air conditioning unit. Although they do not contribute to the size of the unit, most have computer controls (circuit boards). Additionally, some will have variable or stepped capacity to save energy but once again it does not add to the unit size.

With homes being tighter, causing less air change from outside, the quality of the indoor air has become increasingly scrutinized.  Many new products have been introduced to humidify the air, clean the air, and replace the inside air efficiently. These can really improve the health of your family especially if a family member has airborne allergies or asthma. Depending on your needs these can be added to an existing system or included on a new system.
