"The service that we received from Aires Heating and Cooling, LLC was great. I really can't say how it could have gone any better. Our furnace broke down, tried a couple easy troubleshooting steps over the phone, and when we couldn't get it going, the tech was over as soon as he could. This is the time of year where he was busy with other customers, so the amount of time we waited was explainable. Didn't have parts right away on his van, but we didn't wait for more than 24 hours before he found another tech that did have the parts for our furnace. Excellent friendly service. Thank you very much for all the help, Aires Heating and Cooling, LLC."

"Austin installed A/C in our newly remodeled home and we will continue to go through him for any future HVAC needs. He was efficient, thorough, and transparent throughout the entire process, answering any questions we had. As well as reassuring us we could reach out to him after the job was done if we ever had any problems down the road. We highly recommend his services and the peace of mind he provides!"

"Mario did a great job cleaning the ducts in our house and our dryer vent. The before and after pictures showed how dirty our vents were and how wonderfully clean they were when he was done. We just moved into our home and it is reassuring to know that everything is cleaned out now. I highly recommend Mario and his duct cleaning business!"

"I called ANG Heating&Cooling looking for a solution to our very dry and uncomfortable situation in our home. Alex came out to our home to have a look at what was going on, within a few minutes Alex had a plan together and we were scheduled for a whole home humidifier, in addition to some added supply and return runs to get that conditioned air moving throughout our home. Let me just say Alex was spot on WOW what a difference very very pleased! very comfortable! Alex was prompt, professional, punctual and very knowledgeable. Alexs was very neat and tidy! A true craftsman of his trade! Everything looks great,great rates as well! I strongly recommend giving ANG a call for any of your future HVAC needs. Thanks again Alex!"

Heating and Air Conditioning questions, answered by experts

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

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.
