Common HVAC Questions
Find quick answers to questions Chattanooga homeowners ask us most often about HVAC repair and maintenance.
What should I do if my furnace is blowing cold air?
Check your thermostat setting first. If it's set to heat and cold air continues, the issue may be a faulty burner, igniter, or heat exchanger. Call for professional service to avoid prolonging discomfort and potential system damage.
How do I know if my thermostat is broken?
Signs include the system not responding to temperature changes, incorrect temperature readings, or the system cycling erratically. Test by adjusting the thermostat several degrees. If nothing happens, have it inspected and repaired or replaced.
How often should I maintain my HVAC system?
Most systems benefit from professional tune-up service once yearly before cooling or heating season begins. Regular filter changes every 1–3 months and occasional inspections help prevent costly repairs.
Is it better to repair or replace my HVAC system?
If your system is under 10 years old and the repair costs less than 50% of replacement, repair is usually the better choice. Systems older than 15 years may be less efficient. We can assess your system and recommend the best option.

Request My Free QuoteRepair or Replace Your HVAC System?
Not sure whether to repair your heating or cooling system or invest in a new one? Consider these factors to help make your decision.
System Age
Systems under 10 years old are usually good candidates for repair. Units over 15 years may be less efficient and closer to end-of-life, making replacement more economical long-term.
Repair Cost vs. Replacement
If repair costs less than 50% of a new system, repair is typically the better choice. If repair costs are approaching replacement prices, upgrading to a new, efficient system may save money over time.
Frequency of Repairs
If you're repairing your system multiple times per year, replacement might be more cost-effective. A new system often comes with a warranty and improved efficiency.

What should I do if my thermostat isn't working?
First, check the batteries and make sure the thermostat is set to the correct mode (heating or cooling). If it still won't respond, there may be a wiring or sensor issue that requires professional troubleshooting. Contact Highland HVAC Chattanooga for thermostat troubleshooting.
