FAQs
What situations are considered an HVAC emergency, and when should I call for immediate service?
An HVAC emergency is any heating or cooling failure that endangers your family’s safety or could cause property damage. Common examples include total loss of heat in freezing weather, an AC shutdown during extreme summer heat, burning or electrical odors coming from the unit, refrigerant or water leaks that threaten walls or ceilings, and any system that repeatedly trips the breaker. If you experience any of these issues in Signal Mountain, call our 24/7 hotline right away. We will triage the problem over the phone and dispatch a technician immediately if it’s urgent.
How fast can your team reach my home in Signal Mountain for emergency service?
Because we maintain technicians on standby around the clock, our average response time within Signal Mountain is 60–90 minutes from the moment your call is confirmed. Factors such as severe weather or road closures on W Road or Taft Highway can occasionally add a short delay, but our dispatch system automatically assigns the closest available technician to minimize wait times. You will receive a text message with the technician’s name, photo, and real-time ETA so you know exactly when help is on the way.
Are your emergency technicians qualified to repair all makes and models of heating and air conditioning equipment?
Yes. Every emergency technician on our roster is NATE-certified, EPA-licensed for refrigerant handling, and factory-trained on all major HVAC brands, including Trane, Carrier, Lennox, Rheem, and Daikin. We stock our service vehicles with the most common replacement parts—capacitors, contactors, igniters, flame sensors, and control boards—so we can resolve more than 85 percent of calls on the first visit. If a specialized part is required, we expedite ordering through our Chattanooga supply network to get you back up and running as quickly as possible.
What can I do to protect my system and my family while waiting for the emergency crew to arrive?
First, turn off your HVAC unit at the thermostat and, if you smell burning or see sparks, switch off the breaker that powers the air handler or furnace. For water or refrigerant leaks, place a pan or towels under the drip to avoid ceiling or floor damage. Keep windows closed in cold weather to retain heat, or open them for ventilation during a summer AC outage. Gather any model numbers, recent maintenance records, and error codes from the thermostat so you can share them with our dispatcher—this helps the technician arrive with the right parts and tools.
How much does emergency HVAC service cost, and do you offer payment options?
Our after-hours diagnostic fee in Signal Mountain is $139, which includes travel, system inspection, and a written repair estimate. Parts and labor are quoted upfront before work begins, and there are never hidden fees. We honor manufacturer warranties and our own one-year workmanship guarantee on emergency repairs. For larger fixes—such as compressor or heat exchanger replacement—we provide zero-interest financing for up to 12 months through Greensky and accept all major credit cards for your convenience.
Is emergency service available nights, weekends, and holidays?
Absolutely. HVAC problems don’t wait for business hours, so our emergency response line is staffed 24/7/365—including holidays like Thanksgiving and New Year’s Day. We rotate on-call technicians to ensure a rested, ready crew is always available. Whether your furnace quits at 2 a.m. on a January night or your AC fails during a Fourth of July barbecue, one phone call brings a certified professional to your door with the parts, tools, and expertise to restore comfort fast.
