					Common Problems, Common Solutions


It never fails. On the hottest day of the year, whether you use a heat pump or an air
conditioner, an HVAC system is going to go out somewhere. A lot of the problems are due to
outdated systems being overworked and simply giving out. This is, unfortunately, normal. We
haven’t yet perfected machines that operate forever. That being said, sometimes when your
heat pump or air conditioner quits working the solution may be simple and you don’t have to
have a technician come out to fix it. So, before you make a service call that will cost you
money, here are a few things you can check to find out if you have a common problem with a
common solution.


1. It sounds obvious, but take a look at your thermostat settings. Remember, a heat pump can
both heat and cool. Make sure someone didn’t accidentally switch it to HEAT. Next, be sure the
system is set to a temperature below room temperature. Sure, this seems so obvious, but
technicians go to service calls every year where someone simply didn’t use their thermostat
correctly. This wastes their time and your money.


2. Check your air filter. If you haven’t been checking it every month, a clogged air filter could
be the source of the problem. Wash a permanent filter or put in a new replaceable filter. Dirty
filters can cause inefficiencies in your system and that can cost you money aside from any non-
essential service calls.


3. It’s possible your house has just blown a fuse. Check your fuses and/or your circuit breaker.
Again, this is a easy solution to a simple problem a lot of people overlook.


4. Check your exterior system for debris like twigs, leaves and grass caught in the coils and fins.
Gently clean these away and make sure there isn’t other debris obstructing the fan blade. Make
sure the heat pump or air conditioner is switched OFF before you do this.


If those don’t solve your problem, then your home heat pump or air conditioner may have
suffered a more serious problem. Call your repairman and make sure you tell him what you’ve
already checked. That will let him know something is actually wrong with your system and save
him time when he gets there.
