"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 FAQs, answered by experts

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.
