"They were great! Our furnace was acting up during the cold snap and we had no heat. Charlie came right over, quickly diagnosed the problem and had it fixed within a day. Very professional and customer focused - we highly recommend Next Level."

"It's been a couple months since Zach with McDonald's Home Solutions analyzed our air-conditioning needs and had Potts and Vince install the Mitsubishi heat pump and duct work. They were amazing and very hard working. The system is working great and makes a huge difference in the comfort level of our house. It's extremely quiet. It operates like a whisper and we hardly know it's on other than the house is cooler. I checked the energy use of the system against our solar panel productions and it hardly makes a difference. It's amazingly efficient. I strongly recommend anyone considering installation of an HVAC system to use McDonald's Home Solutions. They're the best."

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"I found Jim's Air Systems through HomeAdvisor, and Josh was the first contractor to reach out to me personally, not through an automated service. From the start, communication with him was excellent. I provided him with a detailed description of the job, along with model numbers and photos of my existing system. He reviewed everything carefully rather than giving me a quick, generic quote. I received another bid for comparison, but the other contractor was significantly more expensive and wanted to upsell me. It was refreshing that Josh understood I had done my research, knew what I wanted, and didn't pressure me into unnecessary upgrades. Josh's team arrived on time, completed the work as scheduled, obtained the required permit, and left my home as clean as they found it. Overall, a great experience and a solid value. I wouldn't hesitate to recommend them."

"Green Core HVAC was awesome to work with! The team did a great job helping us pick the perfect AC unit for our home. They showed up on time, got the new AC installed quickly, and left the place spotless. Our house is cooler and more comfortable than it’s ever been. You can tell these guys really care about doing a great job. I’d 100% recommend Green Core to anyone needing AC work. Super professional, super friendly, and they really know what they’re doing!"

"Rick and his team were awesome. They were very thorough, put everything they moved in my garage back and Rick made sure to have me check both the heater and AC once installation was complete. He also installed my smart thermostat for me. I would highly recommend Rick and his team."

"The technician at Ridgeback was able to fix a mini-split we had installed by another company 3 years ago. The company that installed it refused to fix it and offered to install another unit if we paid for it. They were terrible to deal with so it was a pleasure to find a company that was dependable and good at getting the job done. I would highly recommend Ridgeback to anyone!"

Air Conditioning FAQs, answered by experts

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

Yes, it’s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your AC runs all the time, your system’s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills.
