"Andrew and his assistant were very professional in their approach to cleaning our air ducts and dryer vent. The services they provided were totally consistent with how they describe their approach to the service they provide. This included the very helpful before and after pictures taken which would convince anyone of the need to have this work performed in their homes."

"Phil was the best. He arrived a few minutes early to the time agreed. He absolutely did an awesome job on cleaning a dryer vent that was in dire need of cleaning. He worked so hard and made sure the job / project was done not only to my liking but to his as well. I would highly recommend Pure Air Experts for any job. I am having him back in two weeks to do a tune up for my furnace. Awesome job Phil"

"I had the opportunity, and the pleasure, to work side by side coordinating with the office manager Maggie. She was so intentive with all my needs and always made it easy to get my questions answered. Maggie kept me informed on every step of this very large process from scheduling a crane and road crew, to getting permits and having the work inspected. SHE MADE THE WHOLE THING SIMPLE. Now the work crews worked quickly to get things running for us. The original plan was to take two days getting the old air conditioners down from the roof and then the new ones up and running. The crews had everything done in less then a day. I could not be happier with my experience with Phoenix HVAC!! I will definitely hire them again!"

Air Conditioning questions, answered by experts

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

The top reason to purchase an HVAC maintenance contract is the fact that it ensures you are detecting problems before they turn into expensive fixes. Secondly, this type of contract provides priority service, which is nice if it’s peak busy season. Finally, an HVAC maintenance contract provides discounts on parts and labor for repairs, which can save you a good amount of money if your unit breaks.

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.
