"SAFE AIR HVAC LLC did an outstanding job installing my new AC unit and furnace. From the first visit to the final walkthrough, their team was professional, knowledgeable, and extremely efficient. They took the time to explain my options, helped me choose the right system for my home, and provided a very fair price. Installation day went smoothly—they arrived on time, worked cleanly, and made sure everything was set up perfectly. The new system runs quietly and keeps my home comfortable, and the difference in air quality and efficiency is noticeable right away. I was especially impressed with their attention to detail and the care they put into their work. If you need a new HVAC system installed, I highly recommend SAFE AIR HVAC LLC. They truly go above and beyond."

"We were very impressed with A & C Heating and Cooling. Their online scheduling tool was convenient, user friendly, and there was a variety of time slots available. The appointment follow up, reminders and arrival tracking map were timely and helpful. Our technician, McKinley, was amazing!!! He was very courteous, knowledgeable and efficient. He diagnosed the problem quickly, installed the needed part, and ran tests to ensure the unit was running at peak performance. He educated us about our unit by explaining how it operates, what caused the problem, and how the replacement part would remedy the problem. We are VERY satisfied with their service. We give this company and our technician our highest rating, and we would highly recommend them to anyone in need of quality heating and cooling installation or service. ."

Air Conditioning questions, answered by experts

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.
