"We noticed a foul smell coming from one of the vents in our HVAC system. We turned the system off and called AC Dave. Dave sent Justin and James to troubleshoot the problem. They quickly found a tear in one of our ducts--and the remains of a dead rodent. They cut open the duct, cleaned it and resealed it. We had heat again, about an hour after they arrived. Very fast and competent service."

"This company was professional, expedient, courteous, and helpful from start to finish. Not having any experience with HVAC, they explained what was needed and why, they helped me with permits and testing as well as accommodating the requirements if my HOA. I highly recommend this company,"

"I recently had both of my AC units serviced by Just Be Cool Supply LLC, and I couldn’t be more satisfied with the experience. Dyon and his team were prompt, professional, and easy to work with from start to finish. They arrived on time, were well-prepared, and took the time to explain what they were doing without rushing through the job. Everything was handled efficiently, and the quality of work was excellent. What really stood out was their honesty and approach. There was no upselling or pressure, just straightforward recommendations and fair pricing. It’s clear they take pride in their work and genuinely care about helping customers rather than just making a quick sale. Dyon is also doing something special beyond the business itself. He actively mentors young people in the trade, helping them build skills and a future. That kind of leadership says a lot about the integrity behind the company. Overall, Just Be Cool Supply LLC is reliable, affordable, and highly professional."

Heating and Air Conditioning questions, answered by experts

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.
