Heat Pump Installation & Repair

Heat pumps are an energy-efficient alternative. They transfer energy from the outside, making them a great way for those looking for an efficient way to heat and cool their home. The repair for heat pumps is often less expensive, because heat pumps don’t have moving parts that can wear out over time. When it comes to installation, heat pumps are relatively easy to install compared to traditional furnaces. Reliable Air can offer advice on whether heat pumps are best for each specific situation, and deliver reliable installation and repair work. 

HVAC Tune-Ups

Regular HVAC tune-ups are an important part of keeping a home or office space comfortable and energy efficient. Tune-ups can help reduce energy bills, decrease the need for repairs, and improve interior air quality. An HVAC tune-up may also extend the life of the system, making it a worthwhile investment. 

Understanding Auxiliary Heating with Reliable Air in San Marcos

What is Auxiliary Heating?

Auxiliary heating is a crucial component of your HVAC system, particularly in San Marcos's cooler months. Our expert technicians at Reliable Air ensure your system's auxiliary heating functions efficiently, providing additional warmth when needed. It kicks in when temperatures drop, maintaining a comfortable environment in your home.

How Can I Stop My Auxiliary Heat from Coming On?

To prevent auxiliary heat activation, set your thermostat's temperature a degree or two below your desired comfort level. This small adjustment can often bypass the need for auxiliary heating, ensuring energy efficiency while keeping your home cozy. If issues persist, reach out to Reliable Air for a thorough inspection and tailored solutions.
