Is the indoor fan running and air blowing out of your vents?

**Your unit may be equipped with a safety float switch that is connected to the condensate drain at your indoor unit. The safety switch could be wired to shut down the outside unit ONLY to prevent further condensate backup and flooding.**

Solution

  • Check for a clogged condensate drain and clear if it appears clogged or there is evidence of water on the floor at the indoor unit or standing water is present inside the condensate pipe. NEVER use any chemicals including but not limited to bleach, vinegar, Drain-O inside your condensate drain. The use of anything OTHER THAN HOT water will cause eventual coil rupture and refrigerant leaks.
  • The use of a Wet Vac is preferable for homeowner fixes of a clogged drain.
  • Give your air conditioner a couple of minutes and see if it cycles on.

***NOTE--- Your unit most likely has a built in time delay. You MUST allow 10 minutes for the time delay to reset and the system to start-up*** DO NOT keep adjusting the thermostat during this time.

Smells from your gas furnace should ALWAYS be evaluated by a licensed professional. Whether the smell you are experiencing is that of an electrical or metallic nature or the rotten egg smell that is injected into the gas lines (by the gas company) to alert technicians and homeowners of a potential gas leak. None of these should be taken lightly or ignored.

Solution

  • Turn the gas furnace OFF.
  • Close the gas valve to the gas line.
  • Leave your home and call the gas company for service.
  • DO NOT OPERATE SYSTEM UNTIL CLEARED BY A LICENSED PROFESSIONAL

Schedule an appointment for repair IMMEDIATELY.

If you are just turning your heat on for the first time this winter, it is not unusual, and in fact, is quite common for you to experience a dusty, burning smell. Most chances are that your furnace is actually burning away that old dust, debris and buildup that is present on your heat pump’s emergency backup electric heat strips. This is very normal. However, should the smell continue or you feel alarmed, scheduling a repair call would be the prudent approach.

Solution

  • Allow the dusty burning smell to dissipate. It should clear within an hour or so, depending upon amount of buildup present.
  • Be sure the A/C- furnace filter is clean and/or replaced as indicated.

This is due to your system operating in the “Defrost Mode”: This happens during the heating season and is actually normal operation of the system. Outdoor condensing coils will tend to have a buildup of ice occur during low outside (ambient) temperatures. This occurs especially during moist conditions. This buildup will cause a unit to loose efficiency by blocking air flow. The system will regularly place itself in “defrost mode” to clear its coil and improve efficiency and airflow.

Solution

  • Continue normal operation.
  • Do not be alarmed should you experience a short burst of cooler air flowing from the air vents. It is actually the air conditioner functioning in the cool setting. The system will activate the supplemental heat to offset this cooling effect during the defrost cycle. The heating cycle will return to normal heating operation when the defrost cycle terminates.

What our clients say about Us

  • Bill’s team did such a great job that I even had them stay for dinner.
    Nate HL
  • The technician was very professional and answered any questions we had. He cleaned up nicely. I would highly recommend One Hour to others!
    Clyde
  • I have been with One Hour Heating & Air for over 35 years....First contact was when they were PJ Heating based in a little site in Bloomingdale, IL. They became American Comfort after that, and now One Hour. I have purchased two furnace and air cond. systems from them as well in that time. Service has always been faultless and I thank them for that.
    JOHN SIEFER
  • Rose is a very friendly and efficient scheduler. She calls the day before to give the customer a friendly reminder of your appointment. Jimmy is very good at his job. If he sees anything questionable during the service call he explains the possible problem and some options as to solutions. He is not high pressure and if you choose another option that is fine. I love having the service contract.
    CAROL KOVACIK
  • i have not had problems with the service. Rose is great and fun to talk to. She is very conscientious. Don C. knows what he is doing and always explains the problems and solving them. I have been with One Hour for 20 years and I will still keep relying on them for my furnance and air conditioning needs.

  • Woke up to a cold house on a Saturday morning and thought OH No ! I called One Hour Heating & Air Conditioning and they were able to come that morning !! Dan arrived to the house and explained the initial cost and proceeded to check out my Furnace. When he found the problem, on the furnace, which was in the crawl space, he came out and explained the costs and my options. I had them fix it and it was done promptly. I have to say that I really felt comfortable with Rose on the phone and with Dan, who was very Professional and A Great Guy. I would love to tell everyone about One Hour Heating & Air Conditioning!! They are honest and will get the job done promptly. I will be using them for all my Furnace and Air Conditioning work!!! Please check them out and don't hesitate to call them. If you look at all the excellent reviews, you will understand what they are about.........
    JIM COLEGRAVE
  • Friendly honest service. Jimmy came to my condo to take a look at the original central heat/AC unit to see if it could be repaired. The heat still works but the AC hasn't blown cool air in 2 years. Jimmy explained that the unit was very old (the unit was installed in the 70s and the maker is now out of business) and showed me that there was a leak in the coolant system that isn't possible to repair due to it's location on the unit. He explained that we could simply bandaid-repair the unit, but the coolant would just leak out. Mike is coming out today (next day) to review options for replacement units. Very happy with my experience so far.
