"My neighbor and I looked into ductless heating and cooling and noticed that Air Tech had great reviews and I know why. We both hired Air Tech after interviewing other companies. The work was completed on schedule. The technicians were courteous and respectful and spread cloth on the floor in the rooms they were working. Anytime I had questions they were more than willing answer them. Even the secretaries in the office are great. I would highly recommend Air Tech."

"I had AC Dave preform three jobs for me over the past few years. (1) New ducts a few years ago. (2) Installed a mini-split heat pump in master bedroom this year. (3) Then a few months later I had him remove my old Central AC and replace it with an 18 SEER heat pump and new coil, all the while leaving my old furnace in place as a back up. Dave and his guys did a great job on all three projects, completing each one in a day. Highly recommended."

"This was the second time Tim has done work for me. He installed the heating system two years ago and now the central air conditioning. His crew was very fast, clean and pleasant. I could not ask for better service.. My son, who is in the business out of state, said the price was very good."

"On a very hot weekend in L. A., CA , I sent an email on a Monday morning around 1:00 AM. Mario from Mor Air called me at 7:00 AM and was able to be at my house by 8:30 AM . My problem was resolved to my satisfaction by 9:30 AM.. We also set up a schedule of regular inspections on my air condoning and heating systems. Mario is my new go to guy for air conditioning and heating issues. The next contact on the list called me at 10:30 AM to find out if I still needed air conditioning repair."

"Sean was great about repairing my disconnected dryer air duct having to go into the crawl space and figure out what was going on. I'm glad he was able to get it done very quickly as well. He also had a very good attitude about doing the work."

"They sent me a guy who was probably did plumbing for ten or fifteen years. Heating and Air conditioning, he did about three years. I had the heating and air conditioner for twenty years, and also bought this unit. The price is really high for an air conditioner. $12,500 if you want it down right. $4000 in the attic. It was $16500 investment. He didn't have what I wanted to hear. The gauges to calibrate anything. Nothing needs calibrating and told him the problem with the thermostat, and since he left he just turned it way down, I am trying to get eighty degrees, and keep it normal temperature. He is trying to get seventy eight, seventy five. Certainly its going to pump a little more colder. He didn't give us a reason why that thermostat isn't working right in the afternoon. He didn't have that answer, or the reason that you could adjust it. Can you adjust that? He had no idea of any adjustments of the thermostat. I didn't ask. I wanted to keep it all the same. I don't know, he didn't had the experience in heating and air, but he had the experience in plumbing. He didn't, and what he wanted for $85, its steep for me, when I just paid $16500, and for the attic ventilation system. I thought he would say $50 or $60. I paid him, and I went to Right Choice to do everything, complimentary. Something to help us out. I didn't ask them, but I would hope they would offer. He wasn't knowledgeable, and didn't know the answer. He wanted a $1000, it takes care of maintenance. Like he just came to the house. That is what he wanted to sell me. I gave him an soda pop, and wanted to see what he wanted to sell me.They sent an really knowledgeable installer. The parts are all knew. I would think they would have followed up, but nothing. Maybe that isn't a lot of money. I wrote a $12,250 check to them. Its a lot of money. I would want them to come out and make the air flows correct."

"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."

"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!"

Air Conditioning questions, answered by experts

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

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.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned.
