An Up-to-date Guide About A/C Troubleshooting & How To’s

  • If the thermostat uses batteries, replace them or make sure that the existing batteries are still in good working order. 
  • If the thermostat does not use batteries, verify that the furnace is plugged in and is getting power (plug something else into the outlet, like a hair dryer, and make sure it turns on).
  • Make sure that the breaker for the FAU (furnaces) in the electrical panel is turned on.
  • If you recently replaced a filter inside the furnace, make sure that the furnace door was reinstalled properly. 

Call us for more information if the above instructions do not resolve the issue.

There are a couple of scenarios that could lead to water leaks from a furnace during a/c operation:

  • If the water leak appears after a rain, then there may be a leak in the furnace venting system on the roof.  
  • Condensing (high efficiency) furnaces may have leaky hoses or clogged drain parts that need to be  repaired or cleaned.
  • The primary condensate drain may be backing up and causing the evaporator drain pan to overflow.
  • The evaporator drain pan may have failed.
  • The evaporator may be icing causing the leak.
  • Poor maintenance – Dirty filter 

All above conditions require professional service.

  • The easiest way is to unplug the furnace for about 15 seconds and then restore power.
  • If the furnace is not accessible, i.e. attic or subfloor, you can gently remove the thermostat from the sub base (try not to pull out the drywall screws). Re-install after 15 seconds.
  • If your furnace is labeled (correctly) in the electrical panel, you can reset the power there for 15 seconds. You will know that it is the right breaker if the thermostat goes blank after you flip the breaker off.
  • Some thermostats have a reset button, check in the installation manual for details.

Call us for more information if the above instructions do not resolve the issue.

  • First, turn the system off, use a shop vac with a brush attachment to gently brush the grill.

All central heating/cooling systems need to have a filter installed. Here are some of the locations they can be found:

Older furnaces

  • Inside the blower compartment of the furnace.
  • Filter housing underneath furnace.

Attic/basement/subfloor systems

  • Central air filtration system – The filter housing is often located next to the furnace on the intake side.
  • 1” filters – The filters are usually in a ceiling air intake grill (check for large grills in the ceiling).

New system

If it is a new home and you can not find the filter, it is advisable to call us for maintenance so we can assess where the filters are located and how many they are

We will provide you with the system maintenance requirements as part of our service.
