Woodbury has grown rapidly over the past few decades into one of the area’s largest suburbs, with rolling hills and ponds dotting neighborhoods around areas like Bailey Lake. Many of these newer homes use ductless mini splits to cool bonus rooms, sunrooms, and additions that don’t connect to the main system. O’Boys Plumbing, Heating & Air has repaired mini splits throughout Woodbury for more than 25 years.

We had a great experience with O’Boys. We had a furnace tune-up done, and Chad was really knowledgeable and informative. He walked us through options and pricing, and helped us understand what to expect with our furnace in the coming years. We look forward to working with O’Boys again.

Signs It's Time to Schedule a Repair

Bonus rooms and additions across Woodbury’s newer neighborhoods often put specific demands on ductless systems. Watch for these signs that repair is needed.

  • Room stays warmer than the rest of the house
  • Loud rattling from the outdoor unit
  • Ice buildup in mild weather
  • Weak airflow from the vents
  • Sudden increase in energy bills
  • System won’t turn on

Since these spaces are often used as extra living area, it’s worth addressing issues quickly to keep them comfortable.

What Happens During a Repair Visit

Our technicians start by reviewing how the system was originally installed, since many Woodbury homes added mini splits specifically for sunrooms, bonus rooms, or additions with unique cooling needs. We check refrigerant levels, electrical connections, and airflow as standard parts of every visit.

Once we’ve found the cause, we complete the repair and test the system under normal conditions to confirm it’s performing properly. For homes near Woodbury’s ponds and wetlands, we also check drainage components, since humidity can build up more in those pockets of the city.

We wrap up every visit by explaining our findings and offering guidance suited to how you use the space.

Repairs We See Often in Woodbury

Given how many Woodbury homes rely on mini splits for sunrooms, bonus rooms, and additions, a fairly consistent set of issues comes up.

  • Improper original sizing
  • Refrigerant leaks
  • Faulty control boards
  • Worn compressor parts
  • Dirty filters and coils
  • Condensate drainage clogs

We take the time to determine the exact cause so the repair actually solves the problem.

Inside a Typical Service Visit

A homeowner named Brad near the Bailey Lake area called us when his sunroom mini split stopped cooling during a stretch of hot summer days. Our technician found the unit had been undersized for the sunroom’s glass exposure, and a low refrigerant charge was making the problem worse.

After recharging the system and discussing whether a larger unit might better suit the space long term, the repair brought noticeable improvement for the rest of the summer. Brad appreciated understanding why his setup needed a bit more attention than a standard bedroom install.

Yes. Even newer systems can develop issues over time, especially in spaces that see heavy use throughout the year.
