As the Summer winds down and the Autumn colors make their arrival, many homeowners are dancing a jig and thanking their air-conditioner for making it through another busy season. Let’s face it, your AC is under a lot of stress as the temperatures have climbed the past 3+ months and as she gets up there in age, a trouble-free Summer is no given. Before your air-conditioner retires for the Winter however, it’s important to make sure it’s ready for next year with an end-of-season tune up.

Be Clean Going Into Storage
Your AC will likely collect some dust and dirt if it is used sparingly or even stored throughout the Winter. Why add to that pile of gunk however? A fall tuneup includes a rigorous cleaning of system components and lubricating moving parts. If these items are put away dirty, that’s just more risk of corrosion and buildup for next Spring. Plus, you want to make sure condensation lines and other hoses are cleaned out or they can get pretty funky over the offseason.
See If Any Problems Have Arisen
With our climate it’s very possible that your air-conditioner will be shut down only briefly. We run our air-conditioners late and start them back up very early into the new year. An end of season inspection is the best window to see if any problems have come up so you can have them repaired when AC technicians aren’t dealing with emergency 24/7 service calls of the Summer.
Budget For Any Big Repairs or Replacements Next Year
Another thing an end of the season inspection does is give you a good evaluation of your system’s condition. If you have costly repairs or replacements coming up, it’s much better to know early and be able to budget for them instead of getting them sprung upon you when the mercury is soaring.
Get Your Warranty Requirements Out of the Way
Most manufacturers require an annual inspection in order to maintain in good standing with your warranty. The Spring will always fulfill that, but you can also get it out of the way for next year by having it performed in the Fall. If you’ve somehow forgotten to have your system serviced back in the Spring, a Fall tuneup will help you keep your warranty (but be prepared for some finger shaming for forgetting).
The Spring tune-up will always be the most important maintenance for your air-conditioner but a fall inspection helps the two seasons work together and transition between each other.

Cleaning Out Gutters
Change the A/C Filter
Of course adding a new system into the mix would seem counter intuitive to saving money but that’s exactly what a mini-split air-conditioner can do. They really are basically mini versions of a central air-conditioner which can be used to cool all or part of the home. Here are some reasons why the middle of the Summer might be the right time to consider a mini-split A/C:
You very much need to take a Goldilocks approach to finding an air-conditioner that is ‘just right.’ An oversized unit will cool the home or business quickly, thus turn off before it can truly ‘condition’ the air. Remember that an A/C is used not only to cool a room, but also to remove moisture and to dehumidify a space. When your air-conditioner is too large, moisture will remain in the room causing it to be very uncomfortable and prone to mold growth.

Installing insulation is not only an inconvenience, if done incorrectly it can present a huge waste of investment. Some people have done more damage to their home during insulating, others have made no change in their utility bills, and even more people have become physically ill during the process. Here’s why insulating is another job you want to leave to the pros:
The savings are real however.
