I always took my home's heating and cooling system for granted. That is until I found myself battling one of the hottest days in years and my air conditioner simply refused to turn on. After contacting my local HVAC contractor, I learned that my cooling coils had frozen over from a lack of maintenance. He did get my AC back up and running that day, but he also helped me to look at my heating and cooling system in a whole new light. I have spent a lot of time over the last few years learning more about how to properly maintain my HVAC system and ultimately lower my energy costs. Today, I would like to share this knowledge with you so that I can help you to avoid some of the costly mistakes I have made in the past.
Trane air conditioners are popular models because they are reliable and energy-efficient. Many HVAC contractors recommend this brand if you are looking to install a new A/C system or replace your old system. If you already have this particular brand, then you know the old motto of "Nothing stops a Trane!". Of course, you should never stop a working air conditioner to fix it yourself, and only your HVAC contractor can stop a Trane for the following repairs.
Living in some of the hottest places in the U.S., you use up a lot of the refrigerant that is initially in air conditioners when they are installed. In fact, if you were to run your A/C every day for a year for at least nine hours each day, somewhere along the ninth or tenth month the cool air would dissipate. The unit would keep running regardless of the lack of cool air produced. You would have to call HVAC services to find out why your new or nearly new unit is running barely lukewarm.
At this point, the unit would desperately need a refill of refrigerant. Then it would be fine again for several more months. You should consider extending the life of your unit by not running it quite as much.
Central air systems require a lot of power. That much power would be a major drain on your home's electrical box, so these units rely heavily on their own fuse box, which is connected to the house fuse box. The A/C unit draws power from both, and can be shut down from one or both locations, depending on the wiring of the system. It is very rare for the fuses in the box outside to die, since they are built to have a very long life. However, one or both can die, and then your HVAC technician needs to check and replace the fuses.
Cooling the Evaporator
The evaporator evaporates water from the refrigerant to turn it into a gas. As such, the evaporator is often hot and needs to be cooled itself. In the event that your unit suddenly starts smoking or putting off excessive amounts of heat, call HVAC services right away. The technician can stop the unit and find out why it cannot cool the evaporator on its own. Internal fans and other components in the system may be to blame, and will need to be fixed before the technician restarts your Trane.Share
