Frequently Asked Questions About Heating and Cooling Diagnostics
How much does HVAC diagnostics cost?
Our diagnostic service is typically $100-$200, which is often credited toward the repair if you proceed. Considering that a misdiagnosis can cost hundreds in unnecessary repairs, proper diagnostics is a smart investment.
Why is my HVAC system making strange noises?
Different noises indicate different problems: banging or popping (ductwork expansion), squealing (belt or motor bearings), clicking (relay or ignition issues), rattling (loose parts), and grinding (motor failure). Our diagnostics pinpoint the exact cause.
Why is my energy bill suddenly higher?
Sudden bill increases often indicate a system problem: failing compressor, refrigerant leak, dirty coils, duct leak, malfunctioning thermostat, or a component running continuously. Our diagnostics can identify the energy drain.
Can you diagnose problems with any HVAC brand?
Yes. We diagnose issues with all brands and types of heating and cooling equipment. Our technicians are factory-trained on major brands and experienced with both common and unusual systems.
