We get asked this a lot: "Is annual maintenance really necessary?" Short answer — yes. Here's why.
If your system is still under manufacturer's warranty, most manufacturers require routine annual maintenance by a licensed pro to keep that warranty valid. No maintenance records, no warranty coverage.
If your system is older and out of warranty, maintenance still pays off — it catches small problems before they turn into expensive (or total system-replacement) emergencies, and it lets us track your system's health over time so you can plan a replacement on your terms instead of scrambling during a no-heat/no-cool crisis.
Case in point: the photos above. We were out on a diagnostic for a new client and found a low-voltage short — caused by the unit's normal vibration wearing a hole through the wiring insulation over time. This is exactly the kind of thing routine maintenance catches before it becomes a problem.
Low-voltage shorts are especially frustrating because they're not always easy to find, and they can cause intermittent failures — the system fails, you call us, and then it mysteriously starts working again before we arrive.
