"Our central air conditioner stopped running, and I called Sharp-Long because they had originally installed the system and had periodically provided maintenance on it in the past. The owner, J.C. Crossley, went out of his way to send a service employee to look at the problem within an hour (it was at the end of the day).  The employee, who was very friendly, courteous and knowledgeable, determined that the coolant had all leaked out, re-charged the system with recycled coolant for free and ran tests preliminary to determining whether we could claim a utility rebate when we replaced the system.  I was extremely grateful for the courtesy extended by Mr. Crossley and strongly considered his bid for replacement, but in the end we did select another bidder. I offered to pay Mr. Crossley for the service call, but he declined the offer.

"I highly recommend Insulation Pros of KC for your insulation needs. Kyle the Sales Manager: made it easy to understand what I needed. Josie the Office Manager: took the time to answer my questions when I called, and was the one responsible for my decision to go with Insulation Pros. The installation crew: Devon, Tyler and Leo were a great team to work with, very personable and just all around nice guys who did a great job with the installation. Tanner - the Production Manager, who came by to see that everything was going like it should. From the first meeting with Kyle to the time the crew drove away, it was easy and pleasant to work with this company and they did a great job. Attached are pictures to show the 22" of insulation in my attic! :)"

"For $39 you don't get very much. First, the receptionist seemed perturbed when I called to get an ETA for the tech. Upon arrival, the (grumpy) tech spent about a half hour. In the past when I paid other HVAC businesses $80+ they were on site an hour or more and seemed more thorough. The tech said nothing about my system or the service, but did leave a list services performed. Tech did not cover his shoes. Also, the tech did not say hello, goodbye or thank you. I think it's worth paying more for established service providers with a proven track record."

Heating and Air Conditioning questions, answered by experts

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

On average, an AC unit lasts between 10 and 20 years. However, the specific lifespan depends on the type of unit, how often it's used, the local climate, and the quality of maintenance. Central AC units typically last 12 to 17 years, while window units have a shorter lifespan of 8 to 10 years. Portable AC units last about 5 to 10 years, and ductless mini-split systems can last up to 20 years. To extend the life of your AC unit, it's important to perform regular maintenance, such as replacing filters, cleaning coils, and scheduling annual professional tune-ups.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.
