"WOWWW! Above & beyond service, courteous & knowledgeable technician, and fair pricing... what more could you want?! I contacted Air Control Systems via Angie's List and (literally) within minutes received a phone call. They were able to send a technician out that same day (rare in todays service industry!) at no extra charge. Nathan was very personable yet prompt. He fixed the issue, while also checking everything else out to ensure peak performance moving forward. The cost was very fair, and I will not be using ANY other company for HVAC issues in the future! Outstanding!"

"Jesus did a wonderful job. Our ducts hadn't been cleaned in forever; dirt and dust would fly constantly ever time the furnace came. Fast, efficient service. Excellent price, senior and veteran discount. Highly recommend this to anyone who is needing this service."

"I've worked with Evergreen since we purchased our home in 2020. They've done a multitude of projects for us, the most recent being installing an entirely new HVAC system (two units inside and out). They are on time, friendly, courteous, and very professional. They even put up with our rather high-strung little poodle. We had multiple companies bid our job, and we chose Evergreen both because we knew they would do a good job and stand behind their products. We also knew they would be great folks to have in our home doing work. It's never easy when contractors are in your living space, but they make it as pleasant as it can be. Thanks to Shaun and his team for doing such a great job for us, many times over!"

Heating and Air Conditioning FAQs, answered by experts

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you’ll have a more efficient unit that’s likely to last longer.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it. 

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.
