"Avi returned my call right away, and followed up right before our scheduled appointment. I had a leaking and corroded taco zone valve ,as well as cool to the touch radiators in my home. Avi assessed and explained the work to be done. I had many quotes from other plumbers and hvac companies. Glad I used Boss Plumbing. The pipe work surrounding the leak looks so new and clean! Best part --He showed me how to bleed my radiators. Remember you get what you pay for!"

"Pete and Isaiah did a wonderful job. They were here close to 6 hours dealing with duct work and dryer vents in my old (1840) house. Also cleaned the airconditioner condenser. They educated me about all the tasks they were working on, responded to my questions and showed me the result of cleaning they had done. I feel really good about the work they did and heartily recommend Duct Kings. Dottie"

Heating and Air Conditioning questions, answered by experts

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. 

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.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.
