"After a frustrating experience with another HVAC company, Cochran was a breath of fresh air. Communication was always consistent. He was here when he said he would be, and when he had other jobs going long he made sure to call me. He was upfront about costs and options for our failing unit. There were a few minor hiccups along the way that came with being a smaller business, but the customer service more than made up for it. Great value for the money. Would certainly recommend."

"I did have Davis & Son repair my Heating system and they did a very good job. When I called to have them install a gas line (about 10 feet), they were going to get back to me with a quote and timeline. That was a month ago - nothing. I called and had another firm complete the work in 3 hours. Disappointed that they never called back."

"Great experience with Flame Tech. George was knowledgeable and responsive. He provided an accurate estimate over email based on a number of photos and a few phone conversations which streamlined the bid process considerably. They replaced my AC in a few hours for a fair price and educated me on other safety considerations related to my furnace. He also helped me diagnose a rattle in my air ducts that would have given me fits. Good price, know-how, and customer service, I would use Flame Tech again."

"Pulled toilet to access drain. Reset toilet after examining drain lines from basement to septic tank. Explained findings in detail, offered opinion and options for correcting situation including continued observation. I would not hesitate for a moment to use Mr Martin again or to recommend him to family or friends. Thanks for a great job and especially on a Sunday!

"Contact was made with Jason and he met with me for a free estimate of what work I wanted performed.. Jason and Chris were hired to service the Furnace and to install new H&A ducts underneath the house. Other work performed by the guys was replacing old and leaking waterlines underneath the house, and hauling away all the old ducts. Hauling an old Heating and Air unit on the side of the house, and doing some mason work to cover the hole. Installing a section of chain link fence and gate. Troubleshooting and replacing an electrical switch in the storage shed. Unclogging and replacing a waterline underneath my bathtub and installing a new shower head and fixtures. Also, repairing a leaking toilet bowl and replacing a rotting section of floor underneath..... Overall, the boys were excellent in their knowledge and work performance. They were easy to talk too and their work ethics was superb... I would without a doubt hire them again should and when the need arise..."

Heating and Air Conditioning questions, answered by experts

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

Signs that your A/C system needs professional service include increased energy bills, uneven or poor cooling, loud or unusual noises, and frequent cycling.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.
