Absolutely horrific! I had 2 mini splits installed in April 2025. The bedroom one has smelled like…read moremold none stop since installed. I was repetitively told that the odor is from "new" chemicals that will "burn off" after several times of being used. WRONG! It's now been approximately 15 MONTHS AND THE ODOR IS STILL THERE! I am also Immune Compromised, which they were fully aware prior to entering my apartment. They left holes in my wall, opened the old heater system and left that opened only to find my cat (registered ESA) hanging out of it as soon as the employee had walked out of my room! The quality of the Mitsubishi mini splits are terrible. During the winter, tenants HAVE to rely on electric space heaters due to our systems failing. I am thorough about reading the owners. I clean my filters EVERY MONTH! STAY AWAY FROM THIS COMPANY!!!!

Paid Baird over $1700 to fix our motor. They came out and fixed it without our knowing, and we…read morereceive a bill. Then just 2 weeks later no heat. Called them back, they came out and said it was the belt slipping. Tech could not give me an answer as to why the belt was slipping. Boss called the office and asked to speak to a manager. Person who answered the phone was very rude. Did speak to manager who was even worse. The employees in the office are very rude to deal with. Will not recommend this company nor will we be dealing with them again.

The woman who answered the phone was so pleasant and was able to have a plumber out within an hour. He was very knowledgeable and was able to fix the problem immediately as well as several other issues I was having with 2 toilets. Another plumber came to assist him and he was also pleasant and knowledgeable. They said we would be mailed the bill. We had a figure in our mind of how much that bill would be and it was considerably lower than we anticipated. I now have a plumber I will call every time. I would highly recommend Czapp & Griffith for your plumbing needs. G Carroll

First clue - it sounds like a freight train, which I asked about. He used the wrong square footage and installed a unit TOO BIG for our ductwork. The system short cycles and it can't push the air through. It leaked refrigerant and we had to have system charged on several occasions (Stan conveniently says it never happened - I have receipts). His contract stated 10 years part and labor but we had to replace a coil (Oct 2025) and $1500 later... system is not working again (Aug 2026). 3 companies recently came out and ALL agreed that the system is too big and NOT WORKING. NOW we need a NEW system. I am reporting him to BBB AND ATTORNEY GENERAL OF PA. Shame on him. Don't fall for his old school blah blah blah. Terrible. I am sure he will have a great response. DO NOT FALL FOR IT.
