How do I know what size mini split system I need?

Sizing a mini split depends on the square footage of the space, ceiling height, insulation quality, window area, and local climate. A space that's too small will run constantly and struggle to reach temperature; one that's too large will short-cycle and leave the air feeling humid. Our technicians perform a proper load calculation — not a rough estimate — before recommending a system size, ensuring you get efficient, lasting comfort.

How long does a mini split installation take?

Most single-zone residential mini split installations are completed in one day. Multi-zone systems — where one outdoor unit connects to two or more indoor air handlers — typically take one to two days depending on the number of zones and the complexity of the installation. We provide a clear timeline before we start so you can plan accordingly.

Do mini split systems require regular maintenance?

Yes. To keep a ductless system operating at peak efficiency, the air filters in each indoor unit should be cleaned every few weeks and the outdoor unit should be inspected seasonally. We recommend scheduling a professional tune-up once a year, which includes checking refrigerant levels, cleaning coils, inspecting electrical connections, and verifying system performance. Pro Mechanical of Texas offers maintenance plans for residential and commercial customers.

Is a mini split better than a central HVAC system for my home?

It depends on your specific situation. Mini splits are the better choice when you need to heat or cool a room addition, a detached shop or garage, a small commercial space, or any area where extending existing ductwork is impractical or expensive. Central systems remain the more efficient and cost-effective option when conditioning an entire home that already has well-sealed ductwork. Our team will assess your property and give you an honest recommendation — not just the option that costs more.

Can a smart thermostat work with my existing HVAC system?

Most modern smart thermostats are compatible with the majority of forced-air heating and cooling systems, but compatibility does depend on your system's wiring and voltage. Some older systems or heat pumps require specific thermostat models. Before purchasing a thermostat, call us — our technicians confirm compatibility, handle all wiring correctly, and program the device so it works from day one.

Do you offer financing for mini split installation?

Yes. We offer financing options to make ductless mini split installation more accessible for homeowners and business owners in Stephenville and surrounding communities. Visit our Financing page at /financing or ask your technician for details during your free estimate.
