Subzero AC & heating | Professional HVAC Repair in Tyler, TX

Large homes in our area often have uneven cooling due to undersized, aging, or improperly zoned systems that struggle with our heat. A new, correctly sized HVAC installation from Subzero includes a professional load calculation for your home's layout. We can design a system with zoning capabilities to deliver consistent, comfortable air to every room, finally eliminating those stubborn hot and cold spots.

Common signs include weak airflow from vents, strange noises (like squealing or rattling) from your indoor unit, the system constantly running but not cooling, or water leaks around the air handler. Our repair service starts with a thorough diagnostic to pinpoint the issue, whether it's a failing blower motor, a dirty coil, or electrical problems. We fix it efficiently to restore proper airflow and system operation, which is crucial for both comfort and energy efficiency.

It depends on the age, repair cost, and performance of your system. If your system is over 10-15 years old, requires frequent repairs, or can't keep up with our summers—leading to high bills and uneven temperatures—replacement is often more cost-effective. We provide honest assessments, comparing repair quotes against the long-term savings and comfort benefits of a new, high-efficiency HVAC installation tailored to your home.
