If you are one of those who likes to put things off… let us help you get ahead and have your comfort system checked to keep it running all season long!

Why you should have your checkup now:

1. Peace of Mind.
During yoursystem checkup our technician will make sure all components are clean and functioning as they should. This will ensure that your system will do its job during the hottest days of the summer and coldest days of winter, and keep you comfortable instead of breaking down when our crews are busiest.

2. Prevent Expensive Problems.
You will not believe how many calls we get every summer about problems that require expensive fixes which could have been prevented with regular and timely maintenance. Our system checkups will not only make your system more efficient and safe but will also help discover any small issues that could turn into major problems.

3. Save on Energy Use.
When we do our inspections and checkups, we look at all the important parts and mechanisms such as fans and compressors and heat exchangers; this helps keep your system working efficiently during the peak seasons and keeps those utility bills under control!

4. Maintain Manufacturer’s Warranty.
If you have a manufacturer’s warranty it may require that you get an annual AC and heating system checkup to maintain the warranty. Some manufacturers stipulate that their warranty is void if their system doesn’t receive regular maintenance.
