What should I do if my HVAC system needs emergency repair now?

If your HVAC system needs emergency repair now, turn the system off and call Johnson Heating, Cooling, and Plumbing for rapid diagnostics and same-visit repairs. Most sudden no-heat or no-cool calls trace to failed start components, safety lockouts, or a clogged drain, which are parts our stocked trucks typically carry. Our Fixed Right, or It's Free guarantee covers completed repairs for six months, giving calm backup while we get you running. We help homeowners around the Trafalgar area stabilize systems quickly without guesswork.

Take these quick steps while you wait:

• Set the thermostat to Off; if you smell burning or hear electrical arcing, switch the HVAC breaker Off.
• If you smell gas, evacuate and call your gas utility from a safe place before contacting a technician.
• If you see water around the indoor unit, power off the system and avoid the area; place a pan or towels if safe.
• Do not keep restarting a unit that trips breakers or shuts down repeatedly.

Have your model number and any error code ready to speed diagnosis.
