1. Clogged Lines
One of the bigger problems we come across on the island is clogged condenser lines in A/C units. The refrigerant flows through the coils to cool things, but these lines can easily get clogged. On top of this, if you don’t regularly clean the vents, you’ll restrict air flow as well. While you can clean the vents yourself, it’s a bad idea to play with condenser lines, which can freeze and injure you. Clogs in either of these systems can stop your air conditioner from working. It’ll constantly turn on and off and never truly get to work, so let us get to work on it for you.
2. Dirty Coils
There’s nothing worse than dirty coils. Dust, grime, and mineral deposits from the salty ocean air build up on the condenser coil over time. When the coil is covered, it doesn’t expel enough heat from the system, forcing it to run harder to cool your home. The increased pressure can overwork your compressor and cause it to fail. You can rinse off your A/C with a hose and even vacuum around it safely with a shop vac. However, don’t try scraping built-up grime, rust, and other particles off the unit – at that point, you need to call in the professionals.
3. Refrigerant Leaks
As you can probably imagine, refrigerant is an important part of a cooler. Over time, the lines holding refrigerant can crack or break, leaking refrigerant and freezing the lines, effectively shutting your A/C unit down. This is a common problem experienced by older units. Replacing these lines is necessary, but this process needs to be done by a professional. Using the wrong lines or filling with too much or little refrigerant can create even more problems. The refrigerant itself is dangerous for the environment, and you don’t want to make things worse.
4. Broken Thermostat
Sometimes the A/C unit is working just fine – the problem is actually in the thermostat. Like your air conditioner, the thermostat needs to be properly and thoroughly cleaned regularly to stay in working condition. Check all settings and be sure the circuit breaker is on, then set the thermostat the 5 degrees warmer or cooler and see if things turn on. If not, you may need to have your thermostat replaced, which a professional is better off installing to keep you safe. Consider an automated or learning thermostat that can automatically control and schedule your cooling and heating to optimize energy usage and maximize savings.
5. Faulty Wiring
Speaking of the circuit breaker, faulty wiring in the thermostat, A/C unit, or even your house can be responsible for these devices not working. A/C units require a lot of power, especially during startup, and if your home’s wiring has a fault, it’s likely overloading the circuit and popping the fuse. Diagnosing your home’s electrical wiring on your own is a bad idea. These lines carry fatal levels of voltage and working on live wires is unsafe even for electricians wearing special clothing to protect against electrical arcs.
Some of these tips and tricks can be performed yourself, but don’t be afraid to call a professional to assist when necessary. HVAC is a complicated subject and our workers are trained and certified in what to do. Give us a call to find out how we can get your A/C unit back up and running today.
