Maintenance help in St. Louis

Around here the equipment works two hard shifts, a cooling season that's long and swampy, then a heating season right behind it. That's why St. Louis systems tend to quit on the worst day of the year, when they're straining hardest. A spring and fall tune-up catches worn parts, dirty coils, and weak capacitors before they turn into a no-cool July or a no-heat January. It's the cheapest work we do, and it prevents the expensive kind.

WHAT WE SEE IN ST. LOUIS

A lot of what we tune up in St. Louis is equipment running past its expected life, older homes, older systems, owners sensibly trying to get another year or two out of them. Clean coils, tight connections, and fresh filters are usually what make those extra years possible.

Questions from St. Louis

When should I schedule an HVAC tune-up in St. Louis?

AC in the spring before the humidity settles in, furnace in the fall before the first hard cold. If you've missed both windows, the best time is simply before the season you're headed into. We book around your schedule, seven days a week.

What if my system breaks down between tune-ups?

Call us. Most repairs happen the same day and common parts ride on the truck, so the first visit is usually the fix. And if you're a tune-up customer, we already know your equipment when something does go wrong, and you get priority on the schedule.
