"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."

"Efficiency Air Inc is a fabulous company with excellent customer service and trained professional installers. I received a quote to install a mini split air conditioner/heat pump and we were overjoyed of the quality of work we received. They showed up on time and installed the system with ease. The install Manager â Deanâ was a true leader and got everything needed accomplished. I would recommend Dean and crew to anyone needing quality service. Thank you again for everything. Your lifetime customer Nathaniel G Santa Clarita, CA"

"Quality Comfort is the BEST! Albert was efficient, effective and knowledgeable about the best way to fix it without breaking the bank. We had 2 other contractors who came out and immediately said we had to replace the entire AC compressor and coil. Several thousands of dollars. Albert and Quality Comfort inspected the system and identified a defective thermostat...that's it! He replaced it and our AC system worked like a charm. He saved us many thousands of dollars. Thank you so much. An HONEST contractor who will be our AC and Heating guy forever....and we will tell all our friends...who would be wise to have Albert and Quality Comfort Heating and Air Conditioning their serviceman too. They are the best!!!"

"The great thing about my experience with United Air was not only the competent job, but their willingness to teach the customer how things work. Having this information better informs me on what to look for to keep my air conditioning system in top shape. This will save me problems down the line. I highly recommend this company."

"I highly recommend Top Energy Solutions. During the heat wave my air conditioning system blew out hot air. I expected to wait days for a technician to come out. Leor sent one the next morning. The technician quickly located the problem and fixed it within minutes. Their employees are professional, courteous and very knowledgeable."

"I couldn't give them a 5 star yet because they are going to come back in the fall when it cools down to replace the ducting, so not done yet. So far so good though, I'm thinking maybe I don't need new ducting!!!"

"Simply put, Robs amazing. Years and years of HVAC experience ooze from this honest and caring guy. Did my install and then some for a more than fair price instead of what the other Angi pros wanted. He’s now my go to guy for any and all AC & Heating issues. Oh and he showed up exactly at the time he told me he would. Amazing"

Air Conditioning questions, answered by experts

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.
