"Newton Williams was amazing and knows everything about ac, heating and electrical and more. I am so relieved. Every year someone comes to fix something. He fixed it all and cleaned the outside unit perfectly. Nobody to the time to explain or do the work he did. He let me know what it should be like and he fixed it. The air smells clean and colder than it used to get. I will never trust anyone else."

Heating and Air Conditioning FAQs, answered by experts

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

Both evaporator coils and condenser coils are recyclable and contain valuable, sellable metals such as copper and aluminum. Not only is it more earth-friendly to take them to a local metal recycling facility, but you can also trade them in for cash. Also, once the coils are removed from the system, they won’t have any traces of refrigerant, so you won’t have to arrange for recycling Freon or R-410A unless you’re disposing of the entire AC system.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.
