"Metro Air did an excellent job! I highly recommend this company, especially Ron, my technician. At first I thought i just needed Freon , then thought it was a bad capacitor, come to find out I needed a whole new outside unit. The price was on the higher end of the spectrum when I googled comparable pricing, however the customer service I received was excellent. All care was kept in keeping my home, inside and outside, clean and tidy. Ron was prompt and pleasant to work with. They work on Sundays, and came out immediately when I called with my air troubles. Great company! Thank you Metro Air!"

"Last Friday, my house got the Clean Heating & Cooling Air Ducts & Vents. I couldn't located this category from the list. It was easy to set up an appointment. There was a cancellation so the company rep called me to clean my duct earlier than my appointment date. Two workers came to my house. Before they started the job, à  they inspected my vent for air and duct cleaning. Show me what the condition and problem is. The Workers were very friendly and showed me every step of what they are going to do. When a few of my vents are not cleanable so they bought a few vents from the Home Depot. And installed it for me. One special size wasn't available so I had to buy it from Amazon. If you decide to clean air and duct and inspect and buy a few vent before they come to clean. Do not buy every vents in your home but buy a few vents that look very filthy. Workers are working very hard. Since they are working without air conditioning, you need to turn off the air conditioning. Please prepare some cold water or some soda for them. Please be nice to them since they are working for your house.à Â"

"Yamil provides one of the best HVAC services in town. I installed both my AC with furnace with him. His knowledge of the field is wide and deep, and his experience is solid. He knows the ins-and-outs of air conditioning and heating like nobody else. Whether it comes to the equipment, or the common failings of different brands, or what works and what doesn't, he always has a ton of good ideas. On top of that, he is extremely responsive and courteous, resulting in a very rare combination of high-level technical know-how and superb customer service. He is also very conscious of saving costs for the customers. This company is my go-to answer for everything related to HVAC. I give him my best recommendations."

"They did an excellent job. The men who put the gutter up were friendly and ready to explain things. The gutters look fantastic. I'm very happy with the decision to choose Clean air pro for my new gutters install. Thanks to Cristian for educating me on the product so thoroughly at the builders convention and even further on our consolation. It definitely helped me understand the price point compared to others."

Air Conditioning FAQs, answered by experts

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. 

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

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.
