How do I know if my system is working properly?
Is it starting to make noises? Is it cooling all areas of the house sufficiently? Have your utility bills gone up for no apparent reason? Has it been taking longer to cool down the space?
Any of these are signs that you may need service to avert any further serious damage to your system as well as keep your home or business comfortable for the people and pets in it.
It is important to have yearly maintenance on your cooling system to keep it at peak performance and help with longevity.
If not all areas are cooling properly, this might be corrected by adding zoning or taking a look at the duct system.
