What Are the Signs of Serious Issues That Would Require Emergency Services?

Knowing when to call for emergency service is critical. If your system doesn't turn on, that's an immediate sign you need professional help. Electrical issues, such as a tripping circuit breaker or a burning smell, are also serious and require immediate attention to prevent further damage or a fire. Strange noises coming from your unit, like a high-pitched screaming or hissing, can indicate a major component failure in either your AC or furnace.

What Should You Do If Your HVAC System Suddenly Stops Working?

If your HVAC system suddenly stops working, there are a few simple checks you can perform before calling a professional. First, verify the thermostat settings. Some units also have a brief delay after being adjusted. Next, check your circuit breaker to see if it has tripped and needs to be reset. If you’ve gone through these basic steps and the system still won’t start, it’s time to contact our experts for a proper diagnosis.

What's Considered Dangerous Heat?

According to the Centers for Disease Control and Prevention (CDC), thousands of people are hospitalized each year due to heat-related illnesses such as heat exhaustion and heat stroke. In fact, extreme heat is one of the leading causes of weather-related deaths in the United States. Dangerous heat conditions typically begin when the heat index exceeds 90°F (32°C), increasing the risk of heat exhaustion. When the heat index rises above 103°F (39°C), the risk of heat stroke and other serious health effects becomes significantly higher. Even nighttime temperatures above 75°F (24°C) can be hazardous, as they prevent the body from cooling down properly. Those most at risk include older adults, young children, individuals with chronic medical conditions, and anyone without access to air conditioning. If your cooling system isn’t working properly or you’re experiencing discomfort during a heat wave, don’t wait—reach out to your local One Hour team to ensure your home remains a safe and comfortable environment. For more information on heat-related health risks and how to stay safe, visit the CDC’s Heat & Health Tracker or HEAT.gov.

“I recently had Steven come out to inspect my home's plumbing, and I couldn't be more impressed! From the moment he arrived, Steven was incredibly professional—punctual, polite, which immediately put me at ease. He took the time to thoroughly explain everything he was checking, walking me through potential issues without any pressure or upselling. His attention to detail was top-notch; he even spotted a subtle leak that could have turned into a bigger problem down the line. During the inspection, Steven recommended installing a new toilet to improve efficiency and prevent future clogs, and his clear reasoning made total sense. I'm already planning to have him back soon to replace our downstairs bathtub—his expertise gives me full confidence it'll go smoothly. If you're looking for a reliable plumber who treats your home like his own, Steven is the guy! Highly recommend—5 stars all the way! Thanks, Steven!”

So far, the employees at this company are very professional, polite and take time to explain things... To some get up, I believe this company has great employees and morals to do the right thing, backed by the company...”

“A team of 5 came and cleaned my air ducts, installed an air sanitizer, worked on heat/air unit. These gentlemen were so kind and professional. Each one introduced themselves to me. Continually asked, if I had questions, and explained the work that was done. The team were: Steven, Brayan, Rolando, Salvatore and Da'mond. EXTREMELY impressed with this team; especially that each one introduced themselves to me. They do INCREDIBLE work. I thought the work would take all day but only took a couple of hours. I highly RECOMMEND them. Thank you to the AWESOME Team!!!”

“Above and Beyond is the review I can give. Dale was on time, thorough, detail oriented and clear in his explanations. He showed us our options and always maintained professionalism. We are going to balance our options and decide what steps to follow but we feel calm and happy with the service provided. Also the team was always willing to help and easy to reach. Pricing is worthy. I would not say expensive neither cheap, is about right and what it is fair with the quality of work provided. Totally recommended, we also schedule a safety electrical inspection that we were looking for and he helped us with the call to the team that will reach the partner company of licensed electricians to do it.”
