"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."

"Once the electrical box was opened and assessed it was apparent that the electrical box was pulled away from the house wall by the ground settling. Much of the wood frame behind the box had experienced water damage requiring long screws to seek enough wood meat to pull the box back to the brick wall. A vertical slip sleeve pipe was installed to adjust for the horizontal piping in the ground settling. The owner agreed to add foam, calking to help seal the wall box to the house wall and add a sloped top cover and sides to add additional protection from future heavy rain. This was an original construction land settling issue that is not uncommon."

"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

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill. 

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.
