10 Things You Didn’t Know About Your HVAC

Air conditioning is a specialty area of service and therefore is something that

most people know nothing about, but when summer hits it is important to be

knowledgable. You also want to feel confident that your money is being spent wisely and

that the work you’re receiving is needed. Well, the best way to feel more confident about

these things is to educate yourself. Here are 10 things you should know about the heating

and cooling system in your home:

1. It requires regular maintenance. Service calls are most often related to lack of

maintenance. The good part about the maintenance is a lot of it can be done yourself.

2. An air conditioning system is a sealed system that is to be extensively leak checked

upon installation. Once your HVAC system has been checked, it should not leak unless

something has impacted the unit. This means the thought that an air conditioning system

just needs recharged every so often is a myth.

3. The pressure and temperature relationship of an air conditioning system is very touchy.

Slight adjustments to either of these two factors can result in problems with the system.

4. Air conditioning repairs are often electrical. Three very common problems are: (1) blown

fuses in the service panel located outside near the condensing unit, (2) tripped breakers at

the main electrical panel and (3) blown capacitors.

5. Air conditioning will usually let you know something is wrong before there is a shut

down that is not electrically related. Routinely check the copper lines in your system for

frost or ice.

6. The condenser coil is where the process of the refrigerant returning from a gas to a

liquid begins. There is no mechanical function here. It is simple, the coils either contain

refrigerant or they don’t. If they don’t, you have a problem on your hands.

7. You may have noticed that lately, the air conditioners that people are having installed

are much larger than those they replaced. This is largely related to the fact that energy

regulations have commanded that the minimum SEER rating (efficiency rating) be

increased over the last few years.

8. It’s a good idea to brush dirt and obstructions from the coils and the drains of your

HVAC system at the start of each cooling season.

9. You can use ductless systems to create temperature zones in your home. A room­by-
room ductless system – sometimes called a multi split, with multiple inside air handlers –

allows you to fit your heating and cooling to your specific needs.

10. Changing your air filter regularly is important. If you don’t change the filter, the air flow

will go down, and the system will not perform well. Not only that, but if the filter is too dirty,

it starts to pollute your home’s air.
