5 Signs It’s Time for a Tune-Up

As the cherry blossoms fade and we head into the warmer days of May, now’s the perfect time to make sure your air conditioner is ready for a BC summer. After months of sitting idle, your AC needs a little TLC to ensure it runs efficiently and reliably when you need it most.

Here at Lewis Maclean, we’ve helped thousands of Langley homeowners get their cooling systems in top shape before the summer heat hits. Here are five clear signs your AC is due for a professional tune-up—and why spring is the ideal time to get it done.

1. Your AC Is Blowing Warm or Weak Air

Is your system struggling to keep your home cool? If the air coming out of your vents isn’t as cold or strong as it should be, it could mean dirty coils, low refrigerant levels, or a failing compressor. A tune-up can catch these issues early—before you’re left sweating it out during a heatwave.

2. Your Energy Bills Are Creeping Up

If your hydro bills are higher than usual this spring, your AC could be the culprit. Dust and grime build-up, clogged filters, and worn parts can make your system work harder than it needs to. A clean, well-maintained unit runs more efficiently and keeps those utility costs in check.

3. It’s Been Over a Year Since Your Last Tune-Up

Like your car, your air conditioner needs regular maintenance to perform its best. If it’s been more than a year since your last service, your system could be losing efficiency—or worse, heading for a breakdown. Annual tune-ups extend the lifespan of your equipment and help keep your manufacturer’s warranty intact.

4. You Notice Strange Noises or Smells

Hearing grinding, rattling, or buzzing? Smelling something musty when the AC kicks on? These are warning signs. Strange sounds and smells can point to electrical issues, mould, or damaged components—all problems that are best caught before the full heat of summer arrives.

5. You Want Peace of Mind This Summer

Let’s be honest—nobody wants to deal with a broken AC when it’s 30°C outside. Booking your tune-up in May means you can enjoy worry-free comfort all summer long. No emergency calls. No sticky nights. Just cool, clean air whenever you need it.

Why May Is the Smartest Time to Book

  • Beat the summer rush — AC service calls spike in June and July

  • Catch problems early — before they become expensive repairs

  • Maximize comfort — your system will be ready when the heat arrives

  • Save money — tune-ups boost efficiency and reduce energy use
