"My experience with Clean Air Genie was great. They were professional and knowledgeable explaining everything to me clearly and provided pictures and videos before and after the work was done. My air ducts were pretty bad (hadn’t been cleaned in 10 years) and they were able to get them very clean and sanitized. I appreciate that their prices were transparent and fair for the work. I will definitely recommend!"

"New Era HVAC was amazing! I own a small business that has a very challenging environment to work around. Jared was extremely professional and minimized the disruption to our routine. We have large warehouse heaters. A few years ago we had one installed by another company. They left a huge mess, took 2 1/2 days to do the work and had no regard for disrupting our business. In contrast, when Jared replaced the second one he was done in one day, left the area clean and neat when he left, and was extremely accommodating with us. We have also had a tankless water heater replaced by New Era and had the same experience. Professional, honest, and reliable - you will not find a better company out there!!"

Heating and Air Conditioning questions, answered by experts

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

No, not all HVAC systems have a fresh air intake, but there are many advantages to having one. For example, a fresh air intake can boost the air quality inside your home and help your furnace run more effectively. Plus, it can make your house more energy efficient, possibly saving you money on your utility costs.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.
