"They did a good job. They gave me a $40 discount since my ducts were not very dirty. My only comment is they left some particles of dry wall chips on my floor and did not vacuum them up."

"I had an absolutely 5-star experience with Precision Comfort. Our air went out on Friday night. I researched, and reviews across multiple platforms were stellar for Precision. I called about 8 p.m., they answered right away, apologized for not having a repairman available right away, but set an appointment for between 10-noon on Saturday. The repairman, Brent, was there by 10:30, appropriately wearing a mask. He was swift to check every part of the AC set-up and quickly found our problem - a bad compressor - and repaired it. The whole thing took 20-minutes. Afterward, I found out that Precision is a local small business, and I was happy to have found our new, permanent, heating and air conditioning company."

"⭐⭐⭐⭐⭐ Air Free Duct Cleaning exceeded all my expectations! Their attention to detail is unmatched, and the entire process was seamless. Scheduling was a breeze, with clear communication and timely notifications about my appointment. I had a last-minute change of plans, but their flexibility allowed me to grant them access to my home while I was away, keeping my maintenance schedule on track. They did an outstanding job, even providing before-and-after photos and videos of my ductwork, which looked spotless! They may not be the cheapest, but their quality and professionalism make them the best in the business. Highly recommend!"

Heating and Air Conditioning questions, answered by experts

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

In some cases, yes, portable air conditioners are worth buying. They’re a relatively affordable option for cooling small spaces. (On average, they cost between $100 and $500 per unit.) Plus, they’re easy to set up, and you can move them around to cool various parts of your home as needed. However, they aren’t the most efficient AC option, and they tend to be noisy.

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.

Yes, adding central air can increase your home value by as much as 10%. Generally speaking, prospective buyers prefer a central AC system over a ductless system or room-by-room AC units. That’s because central air conditioning blends into the home easier than individual room air conditioners and typically has less equipment to maintain.
