"I used their website feature to request a tech for residential A/C repair for the following day. But I received a phone call from Cytech a couple of hours later asking if I wanted service earlier as they had a tech available at that time, which worked out even better for me. The service call and repair was completed in 45 minutes after tech arrived in a efficient and professional manner. Tech even went above and beyond the repair and fixed up a couple of minor issues without charging me anything additional. I'll will be calling them again in the future should I need HVAC services!"

"Great thermostat installation service. The technician was punctual, professional, and made the entire process easy to understand. The new thermostat works perfectly, and they took the time to ensure everything was properly configured before leaving. Excellent customer service and quality work. Highly recommend!"

"We were very impressed with the work and knowledge Chris and Leslie provided to us while servicing our house. We originally had scheduled for a cleaning to have a smoke smell removed from prior renters and while they were here they brought other issues to our attention. Long story short, all issues were resolved in a professional and timely manner. Not only did they get the smell out of our house they provided us with vital information about what they did and why they did it. Also, they provided us with information to help us maintain the air ducts to prevent further issues. We will definitely be using their services again."

Heating and Air Conditioning FAQs, 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.

To keep a window air conditioner in good working order, you should clean the filter regularly, inspect the seals, and store the unit properly during the off-season.

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
