Darst Heating and Cooling | Certified HVAC Repair in Aurora, MO

Smart thermostat issues, like connectivity problems or erratic behavior, are common in our area. At Darst Heating and Cooling, we start by diagnosing whether the problem is with the thermostat itself, your home's Wi-Fi network, or the HVAC system's wiring. Our technicians are experienced with various smart thermostat brands and can often resolve the issue through recalibration, firmware updates, or proper wiring. If a replacement is needed, we can recommend and install a compatible, reliable model that works well with your specific heating and cooling system.

We recommend scheduling professional HVAC maintenance at least once a year, ideally in the spring for your cooling system and in the fall for your heating system. Regular maintenance helps prevent unexpected breakdowns during Aurora's hot summers and cold winters, improves efficiency to lower energy bills, and extends the lifespan of your equipment. Our maintenance service includes cleaning critical components, checking refrigerant levels, inspecting electrical connections, and ensuring your system is operating safely and at peak performance.

While we always aim for a cost-effective repair, replacement may be the better long-term choice if your system is over 15 years old, requires frequent and expensive repairs, or is no longer energy-efficient, leading to high utility bills. Other signs include uneven heating or cooling throughout your home, excessive noise, or if the system uses R-22 refrigerant, which is no longer produced. We provide honest assessments, comparing repair costs against the benefits and potential savings of a new, more efficient system, and offer a selection of quality units to fit your budget and needs.
