Mini Split Repair in Santa Ana, CA

Why Homeowners in Santa Ana Call Us for Ductless Mini-Split Repair

When a ductless system fails, many people worry that every contractor will try to sell them a brand-new unit. Our customers often tell us they chose 20th Century Air because we focus on what is right for them and their home, not on selling the most expensive option. One customer story that gets repeated is about our owner fixing an older unit that another company wanted to replace, simply because repair was the honest choice.

We have been a family-owned and operated HVAC company since 1987, and we treat every service call as the start of a long-term relationship. Our technicians are licensed, insured, and trained to work on all makes and models of ductless mini-splits, from single-room wall-mounted units to multi-zone systems in larger homes and small commercial spaces. Because we work across Orange, Los Angeles, and Riverside Counties, we see just about every type of installation and problem you can imagine.

Pricing is a major concern for most families and businesses. Customers who collect multiple quotes routinely tell us that our prices are among the most competitive they receive, especially on larger projects. We provide free estimates and clear pricing before any work begins, so you know the cost before you decide. For bigger repairs or when a system truly does make more sense to replace, we offer payment plans and financing through Service Finance to help keep essential comfort within reach.

Professionalism also matters. Reviews often mention our technicians arriving on time, treating homes with respect, and keeping work areas clean, right down to details like wearing shoe covers. When you combine that with our A+ BBB rating and our position as a leading installer of new heating and air conditioning systems in Orange County, you get a team you can trust with your ductless system.

Common Ductless Mini-Split Problems We Repair

Ductless systems are reliable when they are installed correctly and maintained, but heavy use in a warm climate can still lead to wear and tear. We handle a wide range of issues for customers in this area. If you are seeing any of these problems, it is a good idea to schedule service before the situation gets worse.

Some of the most common issues our technicians diagnose include units that blow warm air when they should be cooling, weak or uneven airflow between indoor heads, unusual noises like grinding or rattling, and foul or musty odors from the vents. We also see frequent calls for water leaking from the indoor unit, ice forming on the coils, systems that short cycle on and off, or error codes appearing on remotes or wall controllers.

These symptoms can come from causes such as clogged filters, dirty coils, low refrigerant levels, blocked or damaged condensate drains, sensor problems, or electrical faults. Left unaddressed, they often lead to higher electric bills, hot and cold spots, or even water damage on walls and floors.

When we provide mini split repair, our goal is to find the real cause, fix it correctly, and help you prevent the same issue from coming back.

What To Do If Your Mini-Split Stops Cooling

When your ductless mini-split suddenly stops cooling, it can be stressful, especially during a warm spell in this part of Orange County. There are a few simple checks you can make before you call us that may save you time. If these steps do not help or you are not comfortable doing them, it is better to leave the system off and reach out to our team.

First, confirm that the unit has power. Check the remote batteries, make sure the system is set to cool and not to fan or dry mode, and verify that the indoor and outdoor units are turned on. If it is safe to do so, you can look at the air filter on the indoor head to see if it is heavily clogged with dust. A dirty filter can reduce airflow and make the system seem weaker than normal.

There are times when you should switch the system off and call right away. If you notice a strong electrical or burning smell, loud scraping or grinding sounds, heavy ice buildup on the indoor unit, or water leaking down the wall, turning the unit off can help prevent further damage. Once you have done the basics, our office can schedule a visit that fits your day. Members of our maintenance club receive priority scheduling, which can be especially helpful during busy seasons when many systems are running hard.

Serving Ductless Mini-Split Owners Across Santa Ana & Orange County

Many properties in Santa Ana rely on ductless mini-splits for spaces that are hard to serve with traditional ductwork. These can include older homes with room additions, converted garages, accessory units, and small offices where running new ducts would be disruptive or impractical. Because we are based in Anaheim and work across Orange County every day, we are familiar with these kinds of setups and the challenges that come with them.

Our team routinely visits customers throughout the area to troubleshoot everything from single head systems that serve one bedroom to larger multi-zone systems covering several rooms or separate suites. That local experience helps us quickly recognize patterns related to sun exposure, building materials, and installation practices that are common here. Many of our new customers come from neighbors, friends, and business owners who refer us after a positive experience, which allows us to keep marketing costs down and maintain fair pricing.

Whether you are managing a rental, caring for family in a multigenerational home, or running a small business that depends on reliable cooling, we work to schedule service at times that make sense for you. Our goal is to be the company you feel comfortable calling whenever you have a question about your ductless system, not just when something goes wrong.
