Ductless Mini-Split Repair & Installation in Madison, WI

Expert Services for Your Efficient Climate Control System

Ductless mini-split air conditioners are an excellent way to achieve zoned air conditioning in your home, especially if the structure has no ducts. They have the advantage of heating and cooling and are highly energy-efficient. If you’re looking into ductless mini-splits for your Sun Prairie, Madison, or Middleton home or you need service for your current system, Action Plumbing, Heating, AC & Electric is here to get the job done.

Ductless Mini-Split Basics

Although mini-splits have a small footprint, they’re complex systems for both heating and cooling your home. Take a look at our basics to answer your questions about ductless mini-splits.

Ductless Mini-Split Installation & Replacement

One of the advantages of mini-splits is their long life span. You can expect your system to run well for around 20 years outside of coastal areas and with proper maintenance. When it’s time to replace your system, you may notice issues like:

  • Fluctuating temperatures

  • Poor performance

  • Climbing electric bills

  • Growing need for multiple repairs

If your ductless mini-split is wearing out and needs a replacement, call Action and make an appointment to find the right option for professional installation.

Call 608-837-3638 to talk to a friendly and knowledgeable representative or schedule an appointment directly online.

Ductless Mini-Split Repair Services

Despite their overall durability, ductless mini-splits can sometimes develop issues that require repair. Some of the more common repairs we perform are in response to:

  • The unit is dripping or failing to drain water

  • The unit is not heating or blowing warm air

  • The unit is not cooling or blowing cool air

  • The system is not dehumidifying the space

  • The system won’t turn on

Our expertise in ductless mini-splits allows Action technicians to quickly diagnose and repair the root causes of these issues and more. We even offer 24/7 emergency service, so you don’t have to wait for critical fixes. Don’t hesitate to call today.

Ductless Mini-Split Maintenance

If you want to get the most out of your mini-split system and keep it running efficiently for years to come, it’s important to schedule regular maintenance. During inspection and tune-ups, Action technicians do the following:

  • Check that the outside unit is clear of debris

  • Inspect evaporator fins and coils

  • Clean or replace filters

  • Confirm or replenish refrigerant levels

  • Empty and clean the condensate pan

  • And more!

Contact Action for prompt and efficient maintenance to keep your mini-split running strong all year round.

Ductless Mini-Split FAQ

How often should I have my ductless mini-split serviced?

Ductless mini-splits should receive maintenance at least once per year, but twice yearly is recommended for optimal effect.

What are the advantages of ductless mini-split systems?

These systems don’t require ductwork for installation, allow you to cool your home zone by zone, make less noise than ducted systems, and are significantly more efficient than central air conditioning.
