"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!!! "

Heating and Air Conditioning questions, answered by experts

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

Clean the filter regularly, inspect seals, and store the unit properly during the off-season.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.
