Heating Repair and Installation in Mission, TX and Nearby Areas

In the Rio Grande Valley, heating systems don’t get daily use. But when the temperature drops, there’s no room for hesitation. Cold mornings arrive fast. Fronts move through overnight. And when a heater isn’t ready, the discomfort shows up immediately.


At Frontier Cooling & Heating, we provide dependable heating services for homeowners and businesses throughout Mission, TX and nearby communities. We see the same problems again and again—systems that won’t start, heaters blowing lukewarm air, furnaces cycling endlessly, and heat pumps that can’t hold a steady temperature. This scenario is usually where people run into trouble, especially after a system has sat idle for months and suddenly gets pushed hard.



When a heating system starts acting off, putting it off rarely helps. Small issues grow. Energy use climbs. Comfort disappears. Our job is straightforward: identify the issue, explain what’s happening in plain terms, and correct it properly so the system does what it’s supposed to do—when you actually need it.

Professional Heating Services from Frontier Cooling & Heating

Heating equipment here doesn’t run year-round, but it still requires maintenance. Dust buildup, worn components, electrical wear, and airflow restrictions often stay hidden until the system is under pressure. That’s when failures show up.



As a local HVAC contractor with deep roots in the Valley, we provide complete heater services for both residential and commercial properties. From routine inspections to full heating system installation and heating system replacement, our approach stays the same. We diagnose carefully. We explain clearly. And we outline realistic options before any work begins.

No rushed decisions. No vague answers. Just solid work and honest recommendations.

Heating Repair Service for Homes and Businesses

When a heater fails, comfort isn’t the only concern. Reliability matters. Safety matters. The overall condition of the system matters.

We provide dependable heating repair service for units that heat unevenly, shut down unexpectedly, or make noises that weren’t there before. These aren’t problems to guess at.


Our technicians handle issues like ignition failures, faulty sensors, airflow restrictions, electrical problems, and worn mechanical parts. Some fixes are simple. Others take time. Either way, the goal stays the same—restore safe, consistent heat without unnecessary delays.



When timing isn’t on your side, we also offer emergency heating services. Cold nights don’t wait for business hours. Neither do we. Emergency calls focus on getting heat restored quickly while still addressing the root of the problem.

Furnace Repair Service and Furnace Services

Furnaces are still common across South Texas, and when they’re working properly, they’re dependable. But when issues start, they escalate quickly.


Our furnace repair service addresses problems like pilot light failures, ignition control issues, blower motor wear, cracked heat exchangers, and airflow concerns. If a furnace is running but not producing heat, cycling constantly, or shutting down on its own, it’s time to take a closer look.



Beyond repairs, our furnace services include inspections, adjustments, and performance checks designed to keep systems operating safely. When replacement becomes the smarter option, we help homeowners evaluate heating system replacement choices based on comfort, efficiency, and long-term reliability—not pressure.

Heating System Installation and Replacement

There are times when repairs stop making sense. Aging equipment, repeated breakdowns, and rising energy costs usually point in the same direction.

We provide professional heating system installation and heating system replacement services tailored to homes and businesses in the Rio Grande Valley. System sizing matters. Equipment selection matters. Installation quality matters.

We take time to evaluate your space, discuss usage patterns, and recommend systems that fit your needs—not just what’s on the shelf. The result is even heating, better efficiency, and fewer headaches down the road.

Heating Maintenance Service and System Cleaning

People often overlook maintenance here, particularly because heaters don't operate continuously. That’s usually where problems start.

Our heating maintenance service includes inspections, safety checks, performance testing, and system adjustments. We also provide heating system cleaning, helping remove dust and debris that restrict airflow and strain components.

Routine service reduces breakdown risk, improves efficiency, and extends equipment life. More importantly, it catches issues early—before they turn into emergency calls.

Commercial Heating Services

Heating problems don’t stop at the front door of a business. In commercial spaces, they affect employees, customers, and daily operations. Downtime adds up fast.

We provide dependable commercial heating services for offices, retail spaces, and light commercial properties. Our work includes heating repair service, maintenance, and equipment replacement for commercial systems. Scheduling matters. Communication matters. Downtime needs to be minimized.

Commercial systems require a different approach than residential equipment, and our team is experienced in handling those demands.
