We look forward to building lasting relationships with our clients and guarantee your satisfaction!

"Integrity, Service, Professionalism & “Technical Know How” - if you are looking for this in a HVAC company – FloBros should be your go to service provider. I’ve worked the Capital District’s Top Tier providers & they fall short where FloBros excels. When I looked to the “big guys” for a simple service request they immediately “blew up” a small request into a new installation. FloBlos was sharp in trouble shooting & to the point in options, I’ve used them multiple times now & will continue to do so in the future. Look no further than FloBros for your HVAC needs!!! "

"I hired Jeff to replace an exhaust fan in my upstairs bathroom. During our preliminary meeting, he provided me with the appropriate measurements to search for a replacement unit. The day the work was scheduled, he was on time.. overall I was very pleased with the results. Before leaving, I told him about a light fixture just outside the bathroom that wasnâ t working. He was able to identify the problem which turned out to be a defective switch. He had the part and was able to repair the light fixture for a small fee. He was very professional with the work he performed."

Heating and Air Conditioning questions, answered by experts

The top reason to purchase an HVAC maintenance contract is the fact that it ensures you are detecting problems before they turn into expensive fixes. Secondly, this type of contract provides priority service, which is nice if it’s peak busy season. Finally, an HVAC maintenance contract provides discounts on parts and labor for repairs, which can save you a good amount of money if your unit breaks.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.
