"It went amazing my kids and I have so many allergies specially in this season and it’s so hard when we can’t even feel good at home because of the dust in the air conditioning duct, I have been paying for many services with different companies and it just worked for few weeks until I hired this company and their work exceeded my expectations. Highly recommended. Thank you for the services"

"This is not my first review of Joe's Plumbing but they just keep knocking it out of the park. Decided to do pipe replacement on a 60 year old home do to multiple leaks. Wanted to get it done before the cold came, and Joe's did the job on time, under budget, and the quality was second to none. When they found they couldn't turn the water off from the street, they kept moving on the job and did a fantastic job. Joe's was the first called and they have not let me down yet. Thank you Ace and Reg!"

"Moved heavy boiler up difficult site. Installed in one day. Very professional and patient in detailed explanations of complex zoning issues. Prices are high in Dutchess Co. compared to other areas of NY. I generally think plumbers are a safer bet for a maintenance plan and longer lasting businesses than most HVAC companies."

Heating and Air Conditioning FAQs, answered by experts

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

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.
