Heat Pumps

Is your heat pump blowing lukewarm air, making a grinding noise you can't ignore, or running constantly while your power bill creeps up? These aren't minor glitches you can put off; they're signs that a critical component is failing or the system is on its last legs. The Mini Split Company has technicians on the road every day, and we're ready to get your comfort back on track.

Heat Pump Installation & Replacement

When it's time for a new system, you need an installation that's done right the first time. We see it all the time: a poorly sized unit struggling to cool a converted garage in the summer or heat a home office during a cold snap. In the San Antonio Metro area, a heat pump has to handle intense humidity and surprising temperature swings, and a one-size-fits-all approach just doesn't cut it. A new, high-efficiency ductless heat pump isn't just about replacing a broken machine; it's about getting precise, zoned comfort that older, traditional systems can't deliver.

Maybe your old unit is nickel-and-diming you with repair bills, or you're finally adding that sunroom and need a dedicated comfort solution without tearing up your walls to add ductwork. We specialize in these scenarios. Our entire focus is on ductless technology, which means we know exactly how to size, place, and install these systems for peak performance and quiet operation. A proper installation is the foundation for years of reliable heating and cooling, and neglecting it is the most expensive mistake you can make. After we're done, we always recommend a consistent Heat Pump Maintenance & Tune-Up plan to protect your investment.

When to Consider a Replacement

• Your system is over 10-12 years old.
• Repair costs are approaching 50% of the cost of a new unit.
• Your energy bills have spiked without explanation.
• The unit can no longer maintain the set temperature.
• It requires frequent or recurring repairs for the same issue.
• You're dealing with excessive noise or vibration during operation.

Heat Pump Maintenance & Tune-Up

Ignoring routine maintenance on your heat pump is like never changing the oil in your car—it's going to end in a bigger, more expensive failure down the road. In our humid climate, we see indoor coils get clogged with grime and condensate drain lines fill with algae, which can lead to water damage, poor performance, and even system shutdowns. A lot of homeowners think cleaning the filter is enough, but that's just scratching the surface.

A professional tune-up is a comprehensive system check. We're not just wiping things down; we're using gauges and meters to get a real picture of your system's health. We test refrigerant pressures, tighten electrical connections that can vibrate loose, clean the indoor and outdoor coils, and flush the drain line. Finding a failing capacitor or a small refrigerant leak during a maintenance visit can save you from a thousand-dollar compressor failure in the middle of July. This proactive care is the single best thing you can do to extend the life of your equipment and keep it running efficiently. If we find a worn component, we can schedule a follow-up Heat Pump Repair & Service call before it becomes an emergency.

What Our Tune-Up Includes

• Coil Cleaning: Thorough cleaning of the indoor and outdoor coils.
• Refrigerant Check: Verifying proper refrigerant levels for optimal performance.
• Electrical Inspection: Tightening all connections and testing capacitors and contactors.
• Drain Line Flush: Clearing the condensate line to prevent clogs and water damage.
• Performance Test: Measuring temperature differentials and airflow.
• Component Check: Inspecting the fan motor, blower wheel, and other moving parts.

Heat Pump Inspection & Testing

Sometimes a heat pump isn't dead, it's just... off. If you've noticed a room isn't as comfortable as it used to be, there's a musty smell when the unit kicks on, or your utility bill seems a little too high, an inspection can get to the bottom of it. This isn't a full repair visit; it's a diagnostic deep dive to give you a clear picture of your system's health. We get a lot of calls from people buying a home in areas like Schertz or New Braunfels who want to know the true condition of the existing ductless system before they close the deal.

Our technicians use specialized tools to go beyond a simple visual check. We'll test the amperage draw on the motors, measure the temperature drop across the evaporator coil, and check for communication errors between the indoor and outdoor units. This process uncovers hidden issues—the slow refrigerant leak that's killing your efficiency, the failing bearing in a fan motor that's about to seize, or the microbial growth in the drain pan that's affecting your air quality. An inspection gives you the data you need to make an informed decision, whether that's a simple cleaning, a targeted repair, or planning for a future Heat Pump Installation & Replacement.

Compare your equipment against our comprehensive checklist by scheduling a Heat Pump Inspection & Testing visit.

Heat Pump Repair & Service

When your heat pump quits, you need a specialist who understands ductless technology, not a generalist who works on them once in a while. We get the emergency calls every day: the unit won't power on, it's stuck in one mode, or it's making a horrible noise. Because we only work on mini splits, we know the specific failure points of these systems inside and out. We can quickly diagnose whether you've got a bad control board, a failed reversing valve, or a faulty thermistor.

In San Antonio, one of the most common problems we fix is a refrigerant leak. The system can't move heat effectively without the right charge, leading to poor performance and eventually a fried compressor. We also see a lot of electrical failures in the outdoor unit from our intense sun and heat, like burned-out contactors and capacitors. Our trucks are stocked with the parts needed for these common ductless repairs, so we can often get your system back up and running in a single visit. We'll give you a straight answer on whether a repair makes sense or if the money would be better spent on a Heat Pump Installation & Replacement for an older, inefficient unit.

Common Heat Pump Failures We Fix

• Refrigerant leaks
• Compressor failure
• Faulty control boards and sensors
• Failed reversing valves (stuck in heat or cool mode)
• Fan motor or blower wheel issues
• Clogged condensate drain lines causing water leaks
• Electrical problems (capacitors, contactors, wiring)

When your system is down, our Heat Pump Repair & Service team is ready to respond across San Antonio Metro.
