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

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.

Our Services

What Our Clients Say

  • Called velocity to come check my new unit because it was having a hard time keeping up in the heat of the day. Troy called when he was 30 minutes away to let us know he was close. Upon arrival, he was very pleasant and professional. He checked the unit, the thermostat, and even got in the attic to check the air handler (it was 114 that day). Troy cleaned the coils, adjusted the thermostat,replaced our filter and gave very good advice on how to operate the unit moving forward. All this and there was absolutely zero pressure for any extra charges on stuff we didn't need. I will use him and his company for good, very positive experience. Great job Velocity!!!!
    Jeffrey H.
  • So happy with the customer service and honesty, highly recommend. Velocity Mechanical came out to replace the compressor on one of our AC units because we were told by an apparently unreliable source that it was the reason our unit wasn't working. This is a very costly repair and we were dreading having to pay for it. After looking at the unit, Troy fixed a few wires that were incorrectly attached and the unit kicked on. After looking it over he told us that the compressor was fine! Our AC was up and running not even 15 minutes after he arrived - his honesty saved us so much money and for that we are so appreciative! We will use them for all our AC/Heating needs in the future.

  • Troy and his staff are helpful and knowledgeable. They are prompt and checked in with me after me the service was complete to make sure A.C. was working up to my expectations. They were the 4th company to work on my A.C. and the first to actually fix it.
    Lisa M.
  • After dealing with horrible service from other HVAC companies that were assigned to fix our issue through American Home Shield warranty it was a breath of fresh air to be able to work with Velocity Mechanical. They were extremely polite, professional, and on top of communication with me, their client. Other companies we dealt with didn't even have the common courtesy to return phone calls. Velocity was able to get out to fix our AC unit very quickly, even in the middle of the hot Summer. Amber and Troy were excellent. As a real estate professional I will recommend this company to anyone! Good to know there are still companies that care about their clients well being. Thanks Velocity!
    Nick A.
  • Troy and his team are great! After having Goettl come out and charge me a fortune and didn't fix my A.C. Troy showed up and quickly and efficiently had it up and running. I wish I would have called them first. We also had them fix a commercial walk in at work. Give his team a call.
