We are proud to save a few hundred service calls every year by helping customers over the phone and have extended some of our resources to our website. If you are noticing a problem with your Heating System, Cooling System, or Indoor Air Quality product please check below for common issues to learn more about them. Not every issue is addressable without a technician's visit, but this site will help you know a little bit more about what it could be and what you can do to help prepare for a technician or what you can do to fix the issue.

Common Checklist
  • Did you check and replace batteries in your thermostat?
    • Batteries can be low enough that the display works but switches to turn systems on and off will not work.
    • Low Battery indicators do not always display when they should.
    • Not all thermostats have batteries, some are hard wired.
  • Did you check your Air Filter? If dirty it can restrict air triggering safety cut-outs.
    • Set routine furnace replacement reminders for yourself. Plugged filters shorten the life of parts costing you down the road.
    • If it's during A/C season check A/C section below for more details.
  • Is the Switch by the Furnace on? Most are wired with a light switch near it. Check breaker too!
Furnace Checklist
  • Check your Air Filter, if dirty replace.
  • Check that the switch by the furnace is on and breaker is on.
  • Check in door to see if there is a code flashing (if standard on or flashing slowly it's fine)
  • Check drains, restricted and backed up drains can stop a furnace.
  • Check batteries (if applicable) in thermostat and replace and verify correct direction of batteries.
Air Conditioner Checklist
  • Check your Air Filter, if dirty and you see condensation on duct work or ice on copper lines -- turn A/C off, and fan on. Wait a few hours for ice to melt.
  • Check that the breaker to the outdoor unit as well as the furnace is on.
  • Check outside to see if the disconnect is on.
  • If you see ice anywhere (or a lot of sweating on duct work), shut it off right away (let us know you saw ice or condensation on duct work!)
  • Check batteries (if applicable) in thermostat and replace and verify correct direction of batteries.
  • If you see water on the floor, it is most likely due to drain lines backed up.
    • Remove hose from furnace and air conditioner (above furnace) and blow through it.
    • If water flows through drains fine it may be the condensate pan blocked. You can take a pipe cleaner into where the drain goes above the furnace, you can also remove that fitting and take a pencil and agitate the dust and build up inside to clear blockage.
Humidifier Checklist
  • Is the drain line cleared out? Try disconnecting and blowing through it.
    • Every so many years it's recommended to replace the drain lines.
  • Is the yellow "replace water panel" blinking and won't reset after you change it?
    • You have to manually reset it by turning the dial all the way up past 7 into test mode. Green light will come on and then blink after 5 seconds, then put it back. It will be reset.
  • Is the light on and water is not flowing through?
    • Could be the in-line water filter or orfice, could also be saddle-valve.
UVPhotoMAX Info
  • Did you know that the unit will chirp yearly for bulb replacement, however the bulb will be effective for two years.
    • If it is chirping and it has only been one year, you can reset it using the recessed reset button.
    • The chirping does not affect the operation, it's just a timer.
  • There are two versions, a white painted one and a stainless steel one.
    • White has 10 Year Warranty, Stainless Steel has Lifetime Warranty (Bulbs Excluded!)
