Even if your air conditioning unit is still working, depending on the type of system in your home today, you could recoup your investment in a new system in as little as three years. However, that doesn’t mean that your system needs to be replaced. Furnaces, air conditioners, and other heating and cooling systems have made tremendous gains in efficiency over the past five years, so if you have an older unit, it is worth taking a look at whether or not a repair is the best investment.

Sometimes a heating and air conditioning system just needs to be repaired rather than completely replaced. You may need air conditioning repair services if there is leaking around the outside unit, the air coming into the house isn’t hot or cool enough, the unit is short-cycling or constantly turning on and off, using the system is consistently resulting in higher-than-normal energy bills, or if there is excessive noise during startup and operation.

While there’s nothing you can do to guarantee your air conditioner or furnace will never need repairs, there are ways to take better care of your system. Changing out the air filters every 3-6 months, making sure nothing is obstructing or interfering with the outside unit, and keeping all vents unblocked in well-used rooms will help keep your air conditioning and heating system operating efficiently.

If you decide to replace the system, the diagnostic fee will be credited toward your replacement purchase.
