Carden Heating and Cooling technicians are always more than happy to come out and check your HVAC units if you are experiencing any issues! Many times technicians will go on calls and find things the customers could have fixed themselves. You can avoid a service fee by checking a few things before you call an HVAC company to come out. We want to walk you through 5 steps to take before calling for a service call.

  1. Check your filter. Filters are used to increase the longevity of your HVAC system. Many of us get busy and forget to check them or change them out. Many times simply replacing the filter can fix all of your problems.  The air filter increases the efficiency of your unit and can improve indoor air quality. If your filter is really dirty, it causes low air flow. When this occurs your unit can actually freeze up. If this happens you might need to turn the system off overnight so it can completely thaw out. A good rule of thumb is to change/ check your filter every month when you get your power bill.
  2. Check your air flow.  Many times a tripped breaker can cause your unit to stop working. Simply check your panel box and see if the indoor breaker has been tripped.  There are breakers that control the inside unit and breakers that control the outside unit. The inside breakers will generally be marked, “furnace or heat”. The outside breakers are marked “A/C”. Also, make sure you check the switch in the attic, garage or basement that controls your furnace. It looks just like a light switch and is often mistaken as one. Simply put it back in “on” position.
  3. Check your outdoor unit. For heat pumps or condensing units in the cooling mode, your outdoor unit must be running. If the outdoor unit is not running, check the breakers marked A/C. You should also check the indoor unit for water in the pan. If the water is stagnant, the drain pipe is probably clogged.
  4. Check your thermostat. When looking at your thermostat, make sure the fan is in the “auto” position.  If it is set to the “on” position, your fan will run continuously and moisture will not have a chance to drip outside.  Make sure you’ve also selected the proper system choice (heat or A/C). Some thermostats also require batteries in the thermostat. Be sure the batteries are not low or dead.
  5. Sign up for a yearly maintenance program. Our yearly program is called the “Energy Savings Agreement.” This is your best option to make sure your HVAC unit is working properly and continues to work properly. Our technicians are trained to maintain all makes and models of HVAC units and catch issues before they get worse. They will do an expert cleaning and tune-up of your system. You will also receive one free service call with repair, priority dispatch and 15% off of any repairs and no overtime or weekend charges. This is all done to save you as much energy and money as possible!
