"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."

"It was installed with a kink in the condensation hose and was not aware that it leaked under our hallway wood floor. This was June 2022. I paid to have a leak detection company come out and say the floor was OK. In August 2022, we ran HVAC for a couple of days during the heat wave and water came out of the HVAC unit, ruining our hallway wood floor. It is 10/29/2022 and we still have not heard from their office on how they are going to fix our floor."

Heating and Air Conditioning FAQs, answered by experts

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

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. 

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.
