I really appreciate their professional service. I have used them for both my home and business…read moreneeds. They are not the cheapest, but I am willing to pay for quality service. I am pretty handy, and sometimes I will learn to fix something myself that turns out just as good or better than a pro, but it might take 5 to 10 times longer. When my AC went out this summer, they came and fixed it within 2 business days. If you have the time and can fix it yourself, you should. Otherwise, get a pro and realize that you are not just paying for their time and equipment, but also their knowledge and experience, which will save you time and sometimes also save you money in the long run.

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!!!!

Beware of their tactics! I was told by the service technician that someone would contact me…read moreregarding a service plan. I did not receive a call but did get an invoice for the plan on my A/C. I immediately called to explain that this was not what I wanted. Was told this would be cancelled and the new plan which included my furnace and A/C would be set up. I'm still being billed for the original plan which I cancelled more than two months ago. Trying to talk to these reps is next to impossible. They said that cancellation must be done within 60 days. I cancelled after 3 weeks. All I have been told is that I have to pay this invoice. How many more people are being duped by this unfair business practice? More people should speak up and a letter to the Attorney General for the State of Pennsylvania seems to be in order.

I worked directly with Jerred and he was amazing! He came out (On Labor Day!!!) and 100% saved me. It was warm, and I had a bunch of family in town for the holidays and an extremely hot house wasn't going to work for me. I called Holtzople around 10 am, they answered the phone live (only company I could find that didn't go to VM) and Jerred was out within a few hours. He was very informative and quick (which was important because, no offense to Jerred, I prefer to spend the holiday with my family instead of him) and didn't even charge extra because it was a holiday. Turns out I had a contactor that went bad (he showed it to me... it was literally burnt at the top) and was a pretty quick and easy fix. I am VERY happy with the customer service, pricing and speed of service. If you have an issue (especially on a holiday) make sure to call Holtzople and ask for Jerred!
