HVAC Troubleshooting in Greater Dallas Fort Worth Area

If your AC is running but not cooling, start with a few quick checks before you call for service. Make sure the thermostat is set to Cool and a few degrees below room temperature. Replace a dirty air filter. Clear leaves and debris from the outdoor unit. Reset any tripped breaker.

• Check for ice on the refrigerant lines; turn the system off to thaw if iced.
• Confirm supply vents are open and not blocked.
• Ensure the condensate drain isn’t backed up. If issues persist in Arlington or Mansfield, schedule a diagnostic.

The $5,000 rule is a simple guideline: multiply your HVAC system’s age (in years) by the repair cost (in dollars). If the total is over 5,000, replacement is usually the better value. If it’s under 5,000, a repair often makes sense. An in-home evaluation in Arlington or Mansfield will confirm the best option and the exact cost.

• Example: 12 years × $400 = 4,800 → repair.
• Example: 14 years × $500 = 7,000 → consider replacement.

Common reasons a thermostat won’t work include dead batteries, wrong mode or schedule, a tripped HVAC breaker, or loose/damaged thermostat wires. Placement problems (sunlight, drafts, or near a vent) can skew readings. Smart thermostats may drop out due to Wi‑Fi or missing power from the C‑wire. Loss of low‑voltage control power can also stop the system. We troubleshoot these issues in Arlington and Mansfield.

Quick checks:

• Replace batteries and set the correct mode.
• Verify schedule/time or use Hold.
• Check HVAC breakers.
• Reseat the wall plate and inspect wires.
• Reboot the thermostat and router.
