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.← Signs Your Ductwork Needs to be Repaired or Replaced Getting Your House Ready for Winter →
