It’s the first really hot day of summer when open windows, sun-blocking shades, and ceiling fans just can’t cut it anymore. They resign themselves to finally turning on the air conditioner (AC)—only to find it blowing warm air, making funny noises, or simply not cooperating at all. It’s a scenario they all dread, and one that professionals at Tassio Temperature want to prevent.
If they are a homeowner in Los Angeles getting ready for a scorching summer, they will want to understand the top causes of air conditioner failures and what to do to prevent or address them.
Bad Circuit Breaker or Fuse
One common cause of air conditioner failure is a faulty circuit breaker or fuse
One common cause of air conditioner failure is a faulty circuit breaker or fuse. Although some customers may be comfortable changing a fuse or blown breaker on their own, it can be somewhat dangerous because they are working with the electrical system. Be sure they have clear, complete, and reliable instructions on what to do, be sure the system is completely cooled down, and ensure the electricity is turned off.
They can also contact one of the professional heating, ventilating, and air conditioning (HVAC) specialists to handle the problem for them. A trained technician may be able to inspect related problems, such as a tripped high-pressure limit switch, and repair those items during the same service call.
Leaking Refrigerant
Most air conditioners require toxic refrigerants to operate properly. And while this refrigerant is contained and perfectly safe in a well-running air conditioning system, a refrigerant leak can be a significant problem.
Not only will a leak affect the air conditioning system’s performance, but it is also bad for the California environment. Highly trained and knowledgeable technicians can help find and repair the refrigerant leak as well as recharge the air conditioning system so it’s working properly once again.
Frozen Evaporator Coil
One way to fight against freeze-ups is to ensure the air filter and ductwork are clean
It’s always a bit disconcerting to notice frost and ice building up on the air conditioner's evaporator coils. Even if they are not an HVAC professional, they probably realize that’s a problem.
One way to fight against freeze-ups is to ensure the air filter and ductwork are clean. Good air circulation is key to keeping frost off the coils and keeping the air conditioner functioning well. Another possibility is that the system is low on refrigerant, causing the system to work much harder to keep the home cool. If changing the air filter does not thaw the system, call one of the professionals to diagnose the cause.
Worn-Out Parts
Time and wear-and-tear will slowly affect the performance of the air conditioner. If the system is several years old, it may be more critical to arrange for a professional inspection on integral components of the air conditioner. Parts like the compressor and fan blades as well as electrical connections can malfunction due to regular use. If a trained technician can replace worn-out parts before they actually fail, they may be saved an emergency repair call.
Damage Resulting From Poor Maintenance
The most important maintenance item is changing the air filter regularly
If they have been neglecting regular maintenance on the air conditioner by skipping its annual inspection and cleaning, they may void the air conditioner unit’s manufacturer warranty and be shortening its lifespan. According to the US Department of Energy (DoE), the most important maintenance item is changing the air filter regularly.
Damage can result from failing to do so or from something as simple as allowing plant growth to block the outdoor condenser unit. Take the time to care for the air conditioner on a regular basis, and have a professional come out to check and clean the air conditioner once a year.
Bad Thermostat
In some cases, the air conditioner may not be at fault for poor performance. If the thermostat is not operating properly, it is not providing the information the air conditioning system requires to turn on or off correctly. This may mean the air conditioner fails to work or cycles too frequently, which can be damaging to the unit in the long run.
If they are in the market to replace the thermostat, take some time to explore the different options. Many affordable options can help they reduce the energy bill by adjusting automatically, and some can be controlled remotely through a smartphone.
