"I called them based on reviews on Angie's list. They were very responsive and quickly came over to look at our older air conditioning unit that was not working. They said that while they could repair, it was better to replace it with a new one because the unit was too old and repairs could not carry warranty. We agreed. The price quoted was reasonable. Richard and a co-worker did the work. They replaced both the AC and furnace units (Trane) with TempStar. Overall, we found Cool Air team to be professional and knowledgable. We have not yet used the AC given the weather has been nice but we will in summer for sure! There is 1 year warranty on labor and 10 years on the unit."

"Quick response. I had another company come out and didn't have a clue after 2 hours. Said they were going to come back with parts ordered and never heard back from them. Gordon identified the problem within 20 minutes or so and provided a quote. Same day repair and completed in less than an hour. Gordon was knowledgeable, professional, and efficient. Price was very reasonable but it didn't matter as AC and Heating is essential when weather conditions are high and low. I'm happy to have AC again in our hottest temperatures of the summer."

"Oh My Gosh! What an amazing company to work with! I can’t stress enough what a pleasure it was having them in my home! John and Lauren worked smoothly and respectful throughout the day explaining everything to me. This is the first time I’ve had air conditioning. If I could give these gentlemen a 10 Star ⭐️ rating I would, period! You will not go wrong using their services from the price quote to a professional, thorough completed job! Thought it would take 2 days but no only one! Thank you John and Lauren ??"

"We had Temp Air install our AC unit. The best decision we ever made. They were fast, reliable and dependable. Excellent customer service, did a phenomenal job. After a couple of years something was going on with our unit, I called them and immediately they send out a technician Juan, who was phenomenal. He explained what the issue was and resolved it asap! Highly recommend this company!"

"Chris came by for a normal AC tuneup and as he was finishing up, we told him about some issues with our dishwasher and master bathroom sink and asked if he knew a plumber. He took care of both our problems right then and there! I’m not sure there’s anything he can’t fix. Chris is our go to guy for EVERYTHING ac/furnace/plumbing and he should be yours too!"

"Tyler Jones from All City Plumbing Air and Electrical did a great job replacing a gas valve in our garage. He was friendly and easy to engage with, clearly knowledgeable, and took the time to explain what he was doing. The work was completed efficiently and effectively, and everything was handled professionally from start to finish. I’d definitely recommend Tyler and All City for plumbing and gas-related work."

Air Conditioning questions, answered by experts

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.

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.
