Air Conditioning Recharge

Another reason your A/C may not be cooling properly is that it needs a recharge. Recharging is one of the most affordable ways to improve the efficiency of your A/C System. An A/C recharge involves refilling the refrigerant inside the HVAC system. It’s important to maintain proper levels of refrigerant to keep you cool and to avoid costly energy bills from overworking your system. Contact us today to schedule a recharge.

Coil Cleaning

If you find that your A/C isn’t cooling as well as it used to, you might need your coils cleaned. To ensure this is done properly, have a professional come out and clean your indoor and outdoor coils. They can also clear out any clogs that may be happening due to debris in the coils.

Coil Replacement

If your A/C system is very old, cleaning the coils may not be enough. You might consider replacing the coils entirely to improve efficiency. Older coils will probably need to be cleaned more often and can be damaged easily. They can also be the cause of higher energy bills. Contact us to see if replacing your coils is the best option for you.
