"Installed two Mitsubishi splits and the work was done in a professional manner by techs who knew what they were doing, were cognizant of the home interior and worked hard not to destroy any of the exterior vegetation during installation. I would without any hesitation recommend this firm to others looking for this type of an upgrade."

Chris came and did everything from the bathroom and the heating system. I will definitely be calling him back to add a mini split in the future. He was professional, punctual and clean. Very knowledgeable you can tell he cares about his clients."

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.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

In some cases, yes, portable air conditioners are worth buying. They’re a relatively affordable option for cooling small spaces. (On average, they cost between $100 and $500 per unit.) Plus, they’re easy to set up, and you can move them around to cool various parts of your home as needed. However, they aren’t the most efficient AC option, and they tend to be noisy.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.
