"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!"

"Chris’s crew was outstanding. They cleaned our crawlspace and didn’t encapsulated it. They were placed ductwork where it was needed. The photographs are clear documentation of a home improvement. I think the cost was reasonable to high, but I have nothing to compare to. In the end, I am quite pleased. The dehumidifiers have lowered the humidity in the living space and eliminated a musty smell that had been present. I can recommend him with no reservation."

Heating and Air Conditioning questions, answered by experts

When your AC contactor goes bad, you might hear chattering or buzzing noises coming from your air conditioner. You may also notice that your AC is running but isn’t cooling your home. In some cases, your air conditioner might not even turn on at all. There could also be physical damage, discoloration, or corrosion around the contactor.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with.
