Fast Resolution with Heating, Cooling, or Water Heater Emergencies

Taking fast action is key with an HVAC or water heater emergency. After receiving your call, our technicians will arrive at your residence as quickly as possible to begin diagnosis and repair. Because gas and electricity are usually involved in both climate control and water heater systems, it's essential for homeowners not to attempt to fix broken units on their own. We have seen too many individuals put themselves in unnecessary danger instead of relying on professionals for emergency HVAC repairs.

Emergency HVAC FAQs

What Are Signs of Serious Issues with My System That Would Require Emergency Services? 

If your system simply won't turn on, this is obviously a reason to give us a call. If you are concerned about any electrical problems (circuit breaker is tripping or you smell burning), this would be another reason to get immediate help. Sometimes, hearing high pitched screaming or hissing sounds can be indicators of serious failure on an AC or furnace unit. If you feel unsafe or you unit just isn't functioning at all, we recommend getting in touch right away. 

What Should I Do If My HVAC Unit Stops Working Suddenly?

Occasionally, an HVAC system may not turn on because of thermostat settings so be sure to double check your thermostat. With some systems there can be a brief delay (of a few minutes) between setting the thermostat and hearing the system turn on. Also, be sure to check your circuit breaker in case it has tripped for some reason and needs to be reset. If you can't locate a clear reason why your system won't start, it's probably time to give our professionals a call. 

What is Considered an Emergency?

Typically emergencies start when your unit does not work or makes unusual noises. It's always recommended that our team address your unique problem with emergency HVAC repairs as soon as possible to avoid further damage on your system.
