"CB Mechanical provided exceptional service. The staff provided a level of friendliness that made me feel as though my time spent on the repairs was time spent with old friends. Charlie provided a lot of detail to his work and even double checked the repairs before completing the job. I feel as though the quality and low pricing makes them a top choice for my household. I promise you wonâ t be disappointed!"

"I had Pro Tech repair two pieces of wooden furniture. They were very cordial and professional. They worked very hard when they were here and treated my furniture very carefully. Both pieces look MUCH better than before!! Although this is the only service I used them for, I believe their specialty is HVAC and I would try them for that if I had the need."

Heating and Air Conditioning questions, answered by experts

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

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.

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible.
