"As far as I know they did great work. I could not watch everything since it involved climbing. After the installation it became difficult to get they to finish all the detail associated with the complete job, i.e., setting up phone access (per agreement) and repairing something unrelated to the AC project, though it was part of the overall agreement. Still, I would give them 5 stars with reservations. I am still waiting for them to complete the job."

"We were very impressed with the work and knowledge Chris and Leslie provided to us while servicing our house. We originally had scheduled for a cleaning to have a smoke smell removed from prior renters and while they were here they brought other issues to our attention. Long story short, all issues were resolved in a professional and timely manner. Not only did they get the smell out of our house they provided us with vital information about what they did and why they did it. Also, they provided us with information to help us maintain the air ducts to prevent further issues. We will definitely be using their services again."

"I would highly recommend this company. Great people! Belinda (office), Tim, Matthew and Travis (sorry didn't catch the 4th worker's name) are such a pleasure to work with. The install of the compressor and air handler was only like 3 hours or so. I couldn't be happier with their service, dependability, communication through the tuff process of working with my home warranty company. Thank you all so much!! Deena Kramer"

Air Conditioning questions, answered by experts

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.
