Even at night with the windows open, the heat can be unbearable. If there is no breeze to offer any relief, you’ll be doing more sweating than sleeping. That is why it is so important to keep your system running efficiently all summer long.

Typical AC Problems

General wear and tear kind of damage can happen to any system, but it’s important to notice the signs before they end up shutting your system down when you are depending on it. Some of the signs that may precede an AC breakdown include leaking refrigerant around the evaporator coil, frozen coils, lukewarm air coming from the vents when it should be cold, knocking or banging noises coming from the main unit and jumps in your energy bill for no apparent reason. If you see any of these signs, don’t wait long before you call for help.

Why You May Need It Replaced

Once your air conditioning system gets up to around the 15-year mark, things will start going wrong just because the system is older and weaker than when it was younger. After so many years, there are also newer and more energy efficient models available that can save you quite a lot of money on your monthly cooling bills. If your system is older and you notice the repair bills are getting into the hundreds no matter what you do, replacing your system with a new one may be the best option. A consultation with your service provider should give you all the answers you need.

Why Work with Professionals?

To ensure your AC system has the best possible care, whether it is with repairs, maintenance or replacements, insist on using a professional, reputable company for all services. There are so many ways to cause damage to yourself and your home when repairing and installing air conditioning systems, it isn’t worth the risk.
