One System That Heats and Cools Your Home
Heat pump installation, repair, and maintenance in Mission for year-round comfort from a single system.
A heat pump provides both heating and cooling without requiring separate furnace and air conditioner units in your Mission home. It works by transferring heat rather than generating it, making it an energy-efficient option in Texas where heating needs are moderate and cooling is used most of the year. Dr Cool and Mr Heat LLC installs, repairs, and maintains heat pump systems that deliver consistent indoor comfort regardless of season.
This service includes evaluating whether a heat pump is right for your home, sizing the system to match your square footage and insulation, and installing indoor and outdoor components. If you already have a heat pump, the service covers troubleshooting issues such as weak airflow, failure to switch modes, refrigerant leaks, and electrical faults. Maintenance visits include cleaning coils, checking refrigerant levels, and testing defrost cycles to keep your system reliable through both heating and cooling seasons in Mission.
If you want to learn more about heat pumps or need service for an existing system, reach out to Dr Cool and Mr Heat LLC to discuss your setup.
Installation begins with a load calculation to determine the correct system size for your home in Mission. The indoor air handler is mounted, the outdoor unit is set on a concrete pad or brackets, and refrigerant lines are connected and tested. The system is charged, tested in both heating and cooling modes, and programmed to match your thermostat.
After installation, you will notice that your home cools efficiently during summer and heats comfortably during winter without switching equipment. Your energy bills may decrease compared to running separate heating and cooling systems, and your indoor air stays filtered year-round.
Repair visits address issues such as a system stuck in one mode, ice buildup on the outdoor coil, or failure to reach set temperature. The technician checks the reversing valve, inspects electrical connections, and tests refrigerant pressures to restore proper operation. Maintenance includes cleaning both coils, checking airflow, and verifying that the defrost cycle activates correctly during cooler weather. This service does not include ductwork modification unless that is part of a separate project.
What Homeowners Want to Know About Heat Pumps
People considering a heat pump or dealing with an issue often ask how the system works, whether it will heat effectively, and what maintenance looks like. These are the most common questions.
What is the difference between a heat pump and an air conditioner?
An air conditioner only cools your home. A heat pump cools in summer and reverses operation to heat in winter, using the same equipment to do both jobs.
Will a heat pump work during a Texas winter?
Yes. Heat pumps are effective in mild to moderate climates like Mission, where winter temperatures rarely drop below freezing for extended periods. If temperatures do fall significantly, a backup heat source can be added.
Why is my heat pump blowing cold air in heating mode?
This often means the reversing valve is stuck, refrigerant is low, or the defrost cycle is running. The technician tests each component and repairs or replaces the faulty part to restore heating function.
How often should a heat pump be serviced?
Most systems benefit from maintenance twice a year, once before cooling season and once before heating season. This ensures coils are clean, refrigerant is at the correct level, and the system switches modes properly.
What happens if my outdoor unit freezes over?
Ice buildup is normal during defrost cycles in cooler weather. If ice does not melt or the unit stays frozen, the defrost control or refrigerant charge may need attention. The technician inspects the system and makes adjustments to prevent future freezing.
