"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."

With more than 48 years of proudly serving the Delaware County, Chester County, and Main Line region, our licensed and certified specialists provide unbeatable heating, cooling, plumbing, and electrical services backed by a 100% satisfaction guarantee—whether it's maintenance, repairs, or installations. Plus, you can always count on Wm Henderson for 24/7 emergency service, seven days a week.

"Repair Service to Fix Gas Boiler - WM Henderson first sends out a tech who is not familiar with gas boilers and admits there is an issue but does not know how to diagnose it. I had to pay $89 for this. Instead of having the right person come out, I had to to actively call again to get someone else to come out. The 2nd tech diagnosed the issue, but wants to charge me the same $89 that I already paid. - and quotes me $380 for the repair - and has to order the part. I agree and then call back the next day to confirm part is on order - and they tell me the charge is $1,015. I asked to speak to a manager to discuss, and no one is available and no one calls me back. I bought the replacement part from a supply where house (confirming it works with my make/model of boiler) and it cost me $165. I have had other scheduling issues with them as well. Don't use them!!!!!!!!"

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."

And with more than 37 years in business, you can always count on Horizon to arrive in fully stocked trucks to get the job started—and done right—right away.

"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."
