I called Browns late Tuesday during a heatwave, and they were able to schedule a service appointment for the next day. The service call cost $125, but that amount goes towards any repair cost if needed so the initial call is essentially free if you need service costing more than $125.

The techs arrived exactly on time at the start of the appointment window, and quickly found the issues (dirty condenser coils, refrigerant top-off, and system sealant to address the small leak). Ramond clearly explained the impact of each along with the cost to fix, then confirmed which services I wanted and what my total would be before starting the work. I also appreciate that Ramond answered all my dumb questions about how air conditioning actually works; he's a great science teacher 🤓.

The cost was less than I expected for a next-day service (coil cleaning $239, sealant $285, and a few pounds of refrigeratant was $370).

During the payment process, the tech didn't prompt for a tip, unlike most companies. So don't forget to ask them for their Zelle/Venmo if you want to send a tip
Quick responses from a professional company. Although it was peak season for AC’s, they were able to send a crew over within 24-hours. This was so critical for us with 3 young kids in the house and the temps rising to 85 degrees.

Angelique on the phone gave clear instructions on what I needed to do before the service guys showed up. Ramod & Eric were courteous and wore shoe covers as they entered the house. They took a quick look and knew what needed to be done immediately.

As a Realtor, I’ve changed many an AC units and their prices were very fair. We ended up repairing instead of a new AC unit. The repair was less than what he originally quoted. How is that for honest service?! Amazing!

They will have to come back for a service ($99) as we ran out of time.

I can highly recommend Browns Heating & Cooling without any hesitation.

Obsessed 10/10. So friendly, really responsive company, cute service techs (big plus haha), honest, fast and reliable. They were literally here the next day. Love them, hate my 30 year old furnace.

Highly recommend these guys. We had a cooling issue, and Steven was here and gone in under an hour. He pointed out the issue and repaired it without talking much.

Highly recommend them! We needed a whole house humidifier because the winter air was making everyone in the house feel sick. The installation was very clean, and they tied it right into the water line without any leaks or issues. The technician showed me how to adjust the humidity level based on the temperature outside, so we don't get condensation on the windows. It's made the house feel much more comfortable, and my skin isn't nearly as dry as it used to be. I’m happy with the service.

I decided to upgrade to a Nest thermostat and scheduled the installation with this company. The technician arrived on time and installed the thermostat quickly. He also walked me through the settings and showed me how to control it through the phone app. The system now adjusts the temperature automatically during the day, which is convenient. It has made managing the indoor temperature much easier. The team from Brown’s handled the installation smoothly and made sure everything was working before leaving.
