"I came home on a warm Friday early evening from work to find that our AC was not working. After making one call to another company who serviced our unit years ago and getting their voicemail, I waited a couple of hours then contacted my friend Maggi from Tyler. She responded immediately and the technician, Jonathan had the AC up and running by 9:30 the next morning. Thank you!"

"Very quick. Prompt & polite. I should have asked them to leave the damaged pieces behind as this was to be an insurance claim. However, my wife was extremely thrilled to get AC back and I was happy not to have to replace entire system recommended by others."

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

Customers say: Quick response

"Ralph and Mike were both very pleasant. Work was done fairly quickly. Only concern was Ralph quoted me a price to complete additional work (some insulation) but work was not done as I was later told by Ralph that it was not needed and we then had to renegotiate a new price after the initial quote. He did however complete other work which was identified by Mike as being needed and work was done well. Overall I think they were reasonable and did a good job. One central air unit and two bathroom fans cleaned for $450."

"I looked at over 10 different mini split installers over a year and had just about given up. It wasn't until I found Kelley's Heating & cooling. They were honest up front and worked directly with an electrician (who also did an amazing job!) to quote me the best price. Mariana in the office worked directly with me to ensure I got all the Energize CT rebates pre-approved and factored into my quote. By far there team was light years ahead of all the other installers I met with who didn't even include electrical. The fact that they are Fujitsu certified was also a big win in my book. I can't say enough positive things about the installation team. They were professional, clean, and organized. Within about 4 hours they had my new mini split wired in looking great and sounding super quiet. Would highly recommend this team."

Air Conditioning questions, answered by experts

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You’ll need to call a pro to diagnose the issue.
