Arizona’s summer heat is extreme, and you want to be cool. your Air Conditioner should be turning off once the set point on your thermostat is reached and then turning back on when the temperature drops below that set point. Is your unit running constantly?
There are a few quick ways to troubleshoot and fix or find the cause of the problem…
1) Dirty coils- The condenser coils dissipate the heat as the refrigerant passes through the coils. If the condenser coils are filled with dirt and debris, they won’t be able to dissipate the heat as effectively. As debris builds up on the coils, the air conditioner will become less efficient, causing the air conditioner to work harder to cool your home.
You can maintain your condenser coils by simply hosing them down. Make sure to turn off the electrical power to your system first.
The evaporator coils are harder to access but they need routine maintenance as well. Dust can build up on the indoor coil because it is continuously being exposed to airflow circulated by the blower. The dust build-up results in poor heat transfer and higher energy bills and the system has longer run times to meet the thermostat setting.
Annual maintenance is key to removing unwanted dirt and dust.
2) Defective thermostat- The thermostat monitors the temperature of the air. When the air temperature rises above a set point, the thermostat activates a switch to provide power to the fan and compressor. If the thermostat is defective, it may cause the compressor to run continuously.
3) Improperly sized system- An undersized system struggles to cool your home, which is why it’s running constantly. This constant running will reduce pressure in the evaporator (cooling) coil until it freezes over. Over time this will increase the wear and tear on the system and reduce its life.
An over sized system won’t effectively remove the moisture from the air. It will have a shorter run time than it should and will be starting and stopping more often resulting in more energy usage and higher electric bills.
4) Dirty filters- When your system’s air filter is full of dirt and debris, airflow is restricted. This will decrease the amount of cool air your air conditioner can produce and will make your air conditioner run more through the day. When your air filter is clogged, your air handler must work harder to compensate.
Dirty filters are the most common reason for an air conditioner break down.
5) High Heat Gain- Adding window coverings and sunscreens, along with making sure you have adequate insulation in your attic and exterior walls will reduce the amount of heat your home takes in during our hot Arizona summer days and decrease the amount of energy your air conditioner consumes to keep your home cool. If your home is not sealed tightly around windows or doors you are losing that precious cool air along with your hard earned money through gaps or non-insulated areas.
6) System needs maintenance- Air conditioning units need regular maintenance to continue operating smoothly and efficiently. We recommend twice a year, in the spring before hot weather arrives and, in the fall, when temperatures cool down again. We will replace any worn parts and confirm your thermostat is working properly and keep you from the hassle of untimely breakdowns and extend the life of your system.
7) Your system is old and needs to be replaced-
Air conditioners have a limited life span and eventually wear out even if they have been properly maintained. Newer systems are more energy efficient and will save money in the long run. There are many options when it comes to system replacement. Be sure to check the SEER rating (Seasonal Energy Efficiency Ratio) when you decide to purchase a new system. The higher the SEER rating, the more energy efficient the system.
Address small issues before they become major problems.
Any of the above reasons can cause your air conditioner to run longer and work harder than it needs to and cost you more money. Your best bet is to contact a professional to let them know your concerns.
