Reliable Heat When You Need It Most

Heating repair and installation services in Mission, Texas for furnaces and heat pumps that are not working correctly.

Even in South Texas, you depend on your heating system during the cooler months when overnight temperatures drop and your home becomes uncomfortable without a properly functioning furnace or heat pump. If your system is not producing heat, blowing only cold air, or failing to reach the temperature you set, you need a diagnostic evaluation and repair that addresses the root cause. Dr Cool and Mr Heat LLC troubleshoots heating systems in Mission for issues including thermostat malfunctions, airflow restrictions, ignition failures, and heat pump reversing valve problems that prevent your equipment from operating safely and efficiently.


Your heating service begins with a full inspection of your furnace or heat pump to determine why it is not working. The technician checks the thermostat, tests electrical connections, inspects the burner assembly or heat pump compressor, and evaluates airflow through the ducts. Once the issue is identified, you receive a clear explanation of what needs to be repaired or replaced and what the work will involve. If your system is beyond repair or too old to justify the cost of fixing it, Dr Cool and Mr Heat LLC provides guidance on replacement options that fit your home and budget.

What Heating Repairs and Replacements Include

Your heating repair in Mission starts with testing your thermostat to confirm it is calling for heat and communicating correctly with your furnace or heat pump. The technician inspects your system for common failure points such as a faulty igniter, a tripped limit switch, a dirty flame sensor, or a malfunctioning reversing valve if you have a heat pump. If airflow is restricted, the blower motor, filter, and ductwork are checked to restore proper circulation.


Once the repair is finished, your system will heat your home to the set temperature, run quietly, and cycle on and off at appropriate intervals. You will notice that cold spots disappear and your furnace or heat pump no longer shuts down unexpectedly.


If replacement is necessary, Dr Cool and Mr Heat LLC installs energy-efficient heating equipment that is sized correctly for your home and compatible with your existing ductwork and thermostat. The installation includes safety checks to confirm proper venting, gas connections, and electrical wiring. You are provided with operating instructions and maintenance recommendations to keep your new system running reliably for years.

Common concerns about heating repairs and replacements

Homeowners in Mission often ask practical questions about heating service, particularly when their system stops working during the few months it is needed most.

Why is my furnace blowing cold air?

Your furnace may be blowing cold air due to a faulty igniter, a tripped limit switch, or a thermostat set to fan mode instead of auto. Dr Cool and Mr Heat LLC tests each component to determine which issue is affecting your heating system.

How long should a furnace or heat pump last?

Most furnaces last fifteen to twenty years, while heat pumps typically last ten to fifteen years depending on usage and maintenance. If your system is near the end of its lifespan and requires costly repairs, replacement may be more practical.

What does a heating system safety check include?

A safety check includes inspecting the heat exchanger for cracks, testing carbon monoxide levels, verifying proper venting, and confirming that all electrical connections are secure. These steps ensure your system operates safely throughout the heating season.

Can a heat pump provide enough warmth in Mission?

Yes, heat pumps work efficiently in Mission because winter temperatures rarely drop below freezing for extended periods. A properly sized heat pump will keep your home comfortable during cooler months without requiring backup heat in most cases.

How often should I have my heating system serviced?

Your furnace or heat pump should be inspected annually before the heating season begins. This allows technicians to catch potential problems before they cause a breakdown when you need heat most.
