McBroom Heating and Air Conditioning Services - Alpharetta's Emergency HVAC Services

If your system is over 10-15 years old, requires frequent repairs, or struggles with uneven cooling—especially during our humid summers—a replacement is often more cost-effective. Older units with dirty evaporator coils also work much harder, spiking energy bills. We provide a detailed assessment, comparing repair costs to the long-term savings and improved reliability of a new, high-efficiency installation tailored for Alpharetta's climate.

Absolutely. Smart thermostat disconnections are a common issue we resolve. The problem often lies in the wiring at the HVAC unit or a compatibility issue with your specific system. Our technicians will check the wiring integrity, ensure proper voltage, and verify compatibility. We can reconfigure the connection or recommend a thermostat that integrates seamlessly with your existing equipment for reliable, remote temperature control.

A dirty evaporator coil is a top culprit for reduced cooling and high energy bills here. When the coil is clogged with dust and pollen, your AC must run longer to cool your home, straining the compressor and increasing wear. As part of our repair service, we perform a professional coil cleaning. This restores proper airflow and heat transfer, allowing your system to cool efficiently, maintain better humidity control, and potentially prevent future breakdowns.
