"Our AC went out on Friday afternoon. The Aire Serv repair tech, came out on Saturday morning and told us what we already knew...that our 21 yr old AC unit needed to be replaced. He gave us some tips to help it limp along until we could have a new unit installed. Bill, the Aire Serv sales rep, met us at our house on Monday. We discussed different equipment and options. He was very professional and knowledgeable. He understood we would be getting quotes from other companies and assured us that his pricing be better. After meeting with three other companies, Bill was proven right. Aire Serv was more than $1000 less expensive than the closest competitor for the same Lennox equipment. We signed a contract with Bill on Tuesday afternoon, with the install scheduled two days later on Thursday! The other companies were 2-4 weeks out on installs. The install team (Richard & Justin) arrived promptly at 9am on Thursday and got straight to work. The removal and install was smooth and painless. They finished up around 5pm and spent an additional 45 minutes explaining how the new equipment worked, how to get the most out of the system, and answering our remaining questions. We went from an old, broken AC unit to a complete high-efficiency HVAC system in less than one week. Thank you Aire Serv!"

"The service for the big deal from One Choice Mechanical for air conditioner tune up was fine. It was fine. They came in and I wasn't there. My mother was able to meet the man who came over. She said that it didn't take very long and everything was fine and paid. It went just fine, it was great. It was worth the money. There were no repairs. He didn't say, well, you need this, you need this, you need this, nothing, no. It was a nice experience. I called by a day or so and set up an appointment and made sure that my mother could make it and she said yes. It was within the same week of the big deal purchase, maybe just a few days or something like that. Everything went smoothly."

"Andrew was very professional and offered my a variety of options to address both needs. At no point did I feel pressured to take the higher priced service or did I feel like he was trying to upsale me with unneeded services. Will always be my first call for heating and air conditioning needs!"

"Ronnie and his crew were outstanding! They installed the split system air conditioning units in five of our rooms and it had been life changing. Our electricity bill has been halved and the units do an incredible job of cooling the entire house. Ronnie had to work around another construction crew s timeline and he was patient and accommodating. His price quote was one third of other air conditioning systems and I am so happy we called him. He is the best!"

"The young man from Greenwell Dustin texted me earlier than I expected which was great and arrived when he said he would. He diagnosed the issue told me what part was needed and told me where I could get it to save some money. Got the part and he installed it and verified everything was working correctly with no leaks of water or natural gas. Dustin will be who I request if I need any other services from Greenwell Plumbing."

"Prompt and reliable HVAC professionals. Kept us informed about the project daily. Took a few days longer than expected but at the end we had a nice system that was installed correctly. Deandre came back for a couple of extra days and strapped the insulated ducts everywhere I requested and even centered up two ducts that were off center. He was awesome! Every member of the five people who came were pleasant, trustworthy and friendly. I felt like we got an excellent job for the price and would recommend them to a friend. I’d like to give kudos To Brice and Deandre for going above and beyond for us though."

Air Conditioning questions, answered by experts

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.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.
