"though I appreciate the emergency Saturday service call (cost 169.00), I thought the additional charge of 303.00 (450.00) for a diagnostic check and repair ( no parts necessary - just less than a hour of manpower) was a bit exorbitant. perhaps I failed to realize that heating/ac personnel are paid on the equivalent scale as neurosurgeons."

About Us- OUR MISSION At Mattioni Plumbing, Heating & Cooling, our mission is to groom the next generation of technicians by honoring our values of 5-Star customer service and operational excellence. OUR STORY For over seventy years, Mattioni Plumbing, Heating & Cooling, Inc.'s dedicated employees have proudly served the Chester County, Pennsylvania area with their knowledgeable, courteous, and professional service. A.F. Mattioni & Sons Plumbing & Heating was founded on the Mattioni family farm along the (back then) very rural Route 113 outside of Downingtown, PA in 1948. The original barn which housed the company still stands! However, a newer, larger building on the family's property is the current home for the third generation of Mattioni’s to run the service-oriented business, but their commitment to quality has not changed. OUR PROMISE Our promise to you is to continue to grow and modernize so that we can provide you with the best products and services. We will continue to stick to our roots of caring deeply for both our customers and our employees. We promise to live this every day and to continue this legacy.

"Overestimated the time to complete an 9 hr job by scheduling a 16 hr window (2 guys x 8 hrs) and charged for 16 hrs regardless. I'd imagine they did the same for the materials, 60 feet of duct needed but they quoted 200. Got the job done, but probably twice the price of what it should have been."

"Very well. Sunny's Services not only moved our new stand up freezer into our house, they removed the old one AND all the packing materials from the new one. They even advised us not to plug in the new one for a couple hours because they tipped it when they moved it. They were on time, courteous and the price was very reasonable."

Heating and Air Conditioning questions, answered by experts

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.
