"There is no other company I'd rather have installing and servicing my air condiition needs. I've been working with Ray and his family for over ten years. I know I call always count of them. I can call them and explain what I'm encountering and they know exactly what is happening and how to fix it. I wil say that five starts or a ten out of ten rating isn't enough. This company is head and shoulders above the competition. A top notch company who carees about their customers. I highly recommend them to anyone."

"Josh was the tech that came out. He was very professional and clean. He was courteous and on time. He spoke clearly about what was going on with the A/C. He had everything he needed right then and there to find out what was wrong. Also, the problem should be fixed in about 2 days which is super fast compared to my experience with other repair companies. I would defiantly recommend."

"Sooner heat and Air did some repairs on my HVAC system. The repairs had to be done, because the company that did the install did not put it to code and it had to be redone. Their prices were fair and the service and experience were top notch. I highly recommend this company for all of your HVAC needs!"

"There was no category for Vent/Duct cleaning so I placed under Central A/C repair. Good customer service, flexible scheduling around wife's medical appointments. Technician and office sent updates as to arrival time. Technicians were masked and put on shoe protectors without being asked. Worked quickly and efficiently. Good team."

Heating and Air Conditioning questions, answered by experts

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

Troubleshooting common issues with your AC often sheds light on a problem with the compressor. Signs that you need to replace a bad compressor include your AC blowing warm air, short cycling (turning on and off), making strange noises, and blowing less air overall. Since these problems can stem from several areas of your AC, always call a local AC repair team to confirm it's the compressor.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.
