HVAC services encompass a very broad variety of residential, commercial, and industrial services. Most people are likely to call an HVAC contractor when they need something repaired, or when they need something installed for the first time. Perhaps you have something a little different going on with one of your heating or cooling appliances, or maybe your ventilation system needs some help. Of course, you should avoid calling the contractor for every little thing. There are some things you should handle on your own, and definitely some things you should check before you call the HVAC contractor. Here is how to determine that you need to call the contractor for something major.
Is It on Fire or Smoking, Does It Smell Foul, or Is It Making Loud Noises?
If your heating or cooling appliances are doing any of the above, definitely call the contractor. It is also quite smart to turn the appliance off until the contractor arrives. That way you avoid any extra damage you might be causing the troubled appliance.
Is It Falling, Dented, or Caved In?
Ventilation systems are meant to last, but weird accidents can cause them to fail. If the ventilation system has falling parts, has severe dents, or is caved in because of something crashing through the floor or walls, that repair will require a contractor. This is not a DIY job at this point, although you might be tempted to try it on your own.
Is It Refusing to Turn On?
Did you check the switches and controls? What about the buttons on the thermostat? Is there an extra emergency on/off switch on the furnace that might be switched to "off"? What about the breaker in the breaker box (or fuse in the fuse box)? Does it need to be flipped or changed? There are dozens of reasons why a heating or cooling appliance might not turn on. Be sure to investigate and test everything you know of before you call a contractor. Otherwise, you may be paying for an expensive service call just to have the contractor flip a switch for you.
Did You Call the Wrong Type of HVAC Contractor?
Some HVAC contractors only do commercial work. Some only do residential work, and some only do industrial work. If you call the wrong contractor, you still have to pay the service call. Make sure that whoever you call is the right type of contractor for the job.
