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.
The main function of your thermostat is to tell your heating and cooling systems when to come on and when to cycle off. Sometimes thermostats don't work as designed. In many cases, simply switching out the thermostat's old batteries for new ones solves the problem. But if your cooling system continues to run or doesn't reach the desired temperature, recheck your thermostat. Your thermostat could have something wrong with it.
What Can You Do About Your Thermostat?
In order to beat the heat and save money on your cooling bills, Energy.gov recommends raising your thermostat to 78 degrees F in the summer. If you live in an extremely humid or hot location, you may set your thermostat below the recommended temperature to stay cool. But if your air conditioning system struggles to reach the temperature you desire, it can run continuously.
Try raising your thermostat's setting to 78 degrees F to see if it shuts down your AC properly. If this doesn't work, set the thermostat a few degrees higher than 78, then wait for your cooling system to catch up with the thermostat's new setting. You can also place a circulating fan in each room to help remove some of the heat.
If nothing changes with your cooling system, even after you try all of the tips above, ask an HVAC contractor like those at Dependable Heating & Cooling for help.
How Do You Solve Your Cooling System's Problem?
An HVAC contractor will check your thermostat to see if there's anything inside it that needs servicing. For example, the electrical contacts inside your thermostat could be rusted or loose from moisture or overuse. Your thermostat may simply be too old to control your cooling system's functions. In this case, you'll need to replace your thermostat with a more suitable device.
If the thermostat isn't the reason for your ailing cooling system, a contractor may check the equipment inside and outside your home for issues. Cooling systems can run continuously if they have poor air flow, a bad compressor, or a blocked condenser coil. If the evaporator coil in your indoor air handling unit freezes up, it can make the system run constantly. A contractor can troubleshoot and test each part in your cooling system to see if you need to repair it or simply replace it.
