It is highly recommended by HVAC contractors and usually required by most warranties to make sure to schedule an AC tune up or annual preventative maintenance for your AC. It is a great, low cost way to ensure you protect and get the most out of your investment. This service typically costs anywhere from $80 to $160, and any that are less or more than that be wary of.
Most people wonder if this is a must and should they really invest money in having this done. What they do not realize is that this can save them a large amount of money down the road. If your trusted contractor comes out and finds that there is a small problem that could lead into a much larger, more expensive problem, that could save you thousands. It definitely is worth that small of a fee to give you and your family a peace of mind as well as comfortable.
