"Travis was awesome. We scheduled and he was here right on time. The job site was neat and he picked and cleaned everything up. He is coming back to move my dryer vent."
Framing the support structure for a second-story deck addition. Pressure-treated posts and beams being installed to extend the outdoor living space and reinforce structural integrity. Project located in a residential backyard setting with access to existing patio slab.
We replaced an aging, inefficient HVAC unit with a new high-efficiency system to improve cooling performance and energy savings. The original unit was outdated, sitting low to the ground, with declining performance and airflow issues caused by poor drainage and landscaping.
In-progress installation of a high-efficiency air handler and furnace system. Wiring in place, connected to updated ductwork with adjacent water heater visible. Clean layout and spacing prepared for final paneling and system test.
Wall-mounted mini-split indoor head unit installed in an unfinished insulated wall. This high-efficiency ductless system provides both heating and cooling for zoned comfort.
Vintage mechanical thermostat from an early 1900s home. A visual reminder of how much heating and cooling technology has advanced. We specialize in upgrading outdated systems with smart, programmable thermostats to improve comfort and efficiency.

"From start to finish I couldn't be more pleased with our experience. Cole Heating and Cooling were a literal God send. After a month w/o ac Brandi and David went out of their way to makebsure we got some. David was very upfront, honest, and fair. I appreciated his determination to try to help us fix a part to our ac. When ultimately he couldn't he again was honest about the sale of our new unit. Working with a local company has been amazing. The install moved super quickly and we now have ice cold ac. If you are looking for a great ac company, look no further! Would highly recommend 1,000%."

"I am about a month late in posting about Danâ s Heating and Air Conditioning. I just randomly remembered to write a review. If ever in need, this is your guy. Quick, fairly priced, and efficient. After our heating quit working I called him up, and he was at the house within the hour. He diagnosed what was wrong with our heating, left to get the part in Springfield and was back real quick (we live in Fair Grove). I didnâ t expect to have my heating back that night, but he put us above all and got it working. It is still working a month later with no issues whatsoever. Thanks Dan!"

Air Conditioning questions, answered by experts

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

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

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.

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.
