Now that winter is finally almost over and spring is on its way, it is time to think about getting your air conditioner serviced. Here are some signs that could signal that it’s time to replace your HVAC system.
1. You set your thermostat at a temperature that should be comfortable, but you have rooms that are not comfortable. There could be a number of problems: improper duct sealing, insufficient insulation, or inadequate air sealing. It does not matter how efficient your HVAC unit is if any of these is the problem.
2. You have problems controlling humidity or dust. Again, leaky ducts could be the problem, but it could also be an improperly sized unit. Changing your air filter monthly can help solve the problem, but even if you don’t have a problem you should make sure to change your filter monthly.
3. Your system is noisy. Your system could be improperly sized or there could be a problem with the indoor coil.
4. Your energy bills are increasing despite constant repairs. As your system ages, it becomes less efficient. As the efficiency of your system decreases, your energy bills increase.
5. Your A/C or heat pump is more than12 years old. At this point, it is time to consider replacing your unit.
6. Your furnace or boiler is more than 15 years old. The good news is you don’t usually have to replace both your heater and your A/C at the same time. The bad news is, at 15 years, it’s time to replace your furnace or boiler.
7. Your thermostat is always set to one constant temperature. Consider getting a programmable thermostat. It can be programmed to control the temperature when you are not home or you are asleep. This is better for your system and for your wallet.
8. Your home scores below 5 on the ENERGY STAR Home Energy Yard Stick. Your score is inversely proportional to your energy usage. So, a low score means high energy usage and that you are probably paying more than you should be. You can find the Home Energy Yardstick at www.energystar.gov.
If any or all of these sound like your home, contact your AC Doctor certified contractor to discuss servicing or replacing your unit.
