A heat pump provides both heating and cooling, so a single malfunction can cause problems throughout the year. Low refrigerant may affect summer cooling and winter heating. Restricted airflow can create uneven temperatures, longer run times, and extra wear on the system.
Air & Drain Works repairs heat pumps that make unusual noises, cycle too often, produce weak airflow, or fail to maintain the thermostat setting. Our technicians look for the source of the problem instead of replacing parts without a complete diagnosis.
Schedule heat pump service when you notice:
A struggling heat pump often puts extra pressure on its compressor, blower motor, electrical controls, and other components. Prompt repairs can limit further damage and restore comfort before the problem becomes more expensive.

Accurate repairs start with an accurate diagnosis. Our technicians test the system before recommending work.
Depending on the problem, the inspection may include:
After the inspection, we explain the issue in plain language. You will know what failed, why it matters, and which repair options are available before you approve the work.
A heat pump failure can become urgent during a summer heat wave or a sharp winter temperature drop. Air & Drain Works offers 24/7 emergency HVAC service for problems that cannot wait until regular business hours.
Turn the equipment off if you suspect an electrical problem or notice a burning odor. Then call Air & Drain Works for service.
The right heat pump can cool and heat your home with one efficient system. Good results depend on proper equipment selection, sizing, ductwork, electrical capacity, and installation quality.
Air & Drain Works provides heat pump installation in San Antonio for homeowners replacing aging equipment, moving to an all-electric HVAC system, or adding comfort to a space that needs its own temperature control.
Heat pumps suit many San Antonio homes because they provide powerful cooling during the long summer season and reverse operation to produce heat during cooler weather.
Before recommending equipment, we evaluate:
A central air-source heat pump connects to ductwork and an indoor air handler. A ductless heat pump can serve additions, workshops, converted garages, older homes without usable ducts, or rooms that need separate temperature settings.
A heat pump should not be chosen based on square footage alone. Accurate sizing also accounts for ceiling height, windows, sun exposure, insulation, air leakage, duct condition, and the home’s layout.
An undersized unit may run for hours and still struggle to keep the home comfortable. An oversized unit may turn on and off too quickly, create temperature swings, and remove less humidity from the air.
Our technicians evaluate the home before recommending a system. Proper sizing supports steady comfort, reasonable energy use, and longer equipment life.
Every installation starts with a review of the home and the existing HVAC setup. Our process may include:
Project length depends on the equipment, electrical needs, ductwork condition, installation location, and any changes required to the system design. We test the completed installation before we consider the job finished.
Heat pump installation costs vary because every home and project is different. The final price may depend on:
Air & Drain Works offers free estimates for qualifying projects and multiple financing options. Our Price Assurance Guarantee may also help you secure a competitive value. We may beat an equivalent written estimate from a reputable competitor by up to 10% after confirming that the proposed equipment and scope of work are comparable.
The cheapest estimate can leave out work required for a dependable installation. We help you compare equipment quality, warranties, installation requirements, expected performance, and long-term operating needs.

Repairing the system may make sense when the equipment has performed reliably, the current problem is limited, and the major components remain in good condition. Replacement may provide better value when breakdowns become frequent or the system can no longer maintain comfortable temperatures.
A faulty thermostat, relay, or capacitor may call for a straightforward repair. A major component failure in an aging system may make replacement the smarter financial decision.
Our technicians explain the available paths without pressuring you. You receive the information needed to choose the option that makes sense for your home.
A heat pump transfers heat between the inside and outside of your home. In cooling mode, it removes heat from the indoor air and releases it outdoors. In heating mode, the refrigerant cycle reverses and brings available outdoor heat into the home.
This setup works well for many homes in San Antonio. The system handles cooling through the extended warm season and provides heat during mild winter weather. Properly selected equipment can also support comfort during the occasional cold front.
The equipment alone does not determine performance. Comfort and energy use also depend on:
A heat pump may struggle if it is too small, has low refrigerant, receives poor airflow, or connects to damaged ductwork. Frequent auxiliary heat use may also point to an equipment, control, or home-efficiency problem.
Air & Drain Works evaluates the whole system so the recommendation addresses the source of the comfort issue.
Heat pumps use refrigerant to collect and release heat. Several components work together to complete that process:
During the summer, refrigerant absorbs heat at the indoor coil. The system moves that heat outside and releases it through the outdoor coil.
During the winter, the reversing valve changes the direction of the cycle. The outdoor unit collects available heat and transfers it indoors.
Problems with refrigerant, airflow, electrical controls, the compressor, or the reversing valve can affect one or both operating modes. A full system inspection helps the technician find the correct cause.
Heat pumps operate during both heating and cooling seasons. That workload makes routine service important for dependable year-round performance.
Maintenance gives a technician the chance to find worn components, electrical issues, airflow restrictions, and performance changes before they cause a breakdown.
Air & Drain Works recommends professional heat pump maintenance twice each year.
A spring tune-up prepares the system for San Antonio’s heavy cooling season. A fall visit checks heating performance, auxiliary heat, defrost controls, and the reversing valve before temperatures fall.
Maintenance cannot eliminate every repair. It can reduce preventable strain and reveal developing problems before they leave your home without heating or cooling.

Yes. Heat pumps work well in many San Antonio homes because they provide cooling during hot weather and heating during cooler months. Performance depends on correct sizing, good ductwork, proper installation, insulation, and regular maintenance.
The price depends on equipment size, efficiency, system features, ductwork, electrical needs, equipment access, and project complexity. An on-site assessment provides a more accurate estimate than a general price quoted over the phone. Air & Drain Works offers free estimates for qualifying projects, financing options, and a Price Assurance Guarantee for eligible comparable estimates.
The schedule depends on the home and the work involved. A standard equipment replacement may take less time than a project that requires duct repairs, electrical upgrades, or changes to the system design. Your estimate will explain the expected project timeline before installation begins.
Heat pumps may produce air that feels cooler than the air from a gas furnace, even when they are heating properly. The system may also blow cooler air briefly during a defrost cycle. Air that stays cold may indicate low refrigerant, restricted airflow, a thermostat problem, a failed reversing valve, or an issue with auxiliary heat.
Consider the equipment’s age, repair history, warranty coverage, efficiency, and current condition. Repair may be practical for a dependable system with a minor fault. Replacement may offer better value when major components fail, repair costs keep rising, or the system no longer keeps the home comfortable.
Schedule service twice a year. A spring visit prepares the system for cooling, and a fall visit checks heating, defrost, and auxiliary heat operation. Check the air filter regularly between professional tune-ups and replace it according to the manufacturer’s guidance.
Many heat pump systems include auxiliary or emergency heat for colder conditions or equipment problems. The right setup depends on the home and the heat pump. Auxiliary heat that runs often may indicate unusually cold weather, incorrect thermostat settings, poor system performance, or a repair need.
