"My dad always told me to have "a guy" for everything, and Ben is definitely my guy for HVAC. He was so kind, punctual, and helpful. He explained everything thoroughly, and gave me options that the big company wouldn't even mention. I have already sung his praises to multiple friends and family."

"EXCELLENT! HIGHLY RECOMMEND. I cannot speak highly enough of Ken's work. He was responsive, competent, pleasant and highly professional. He was also willing to come out to the north part of town (we are in Colbert). We had a couple of projects -- one rather urgent (major ice load in our eaves after the heavy snow storm that was causing water flow issues around the house) and a minor issue related to our washing machine water hookup. He diagnosed the problems and tended to their solutions within a day of calling him. He cleaned up everything when he was done and left our house better than when he showed up. We are new to the area and will use him for any handyman job we need from here on out."
Using a hose with a nozzle, ladders, brushes and gloves, I removed tree debris from the gutters on this single story residence.
Great looking house.
The plow truck blocked my client in leaving her now way out. I quickly cleared a road in and proceeded to the front door.
Heavy snow removal work up on a roof top.
This is what the project looked like just after paint went on.

Heating and Air Conditioning FAQs, answered by experts

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

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.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected.
