His work and crew was top notch, he took the time to walk me through the whole system, things to look out for in the future. Did not try to upsell me on things I didn't need like the other three prior companies and took his time to do the job right and clean up after himself leaving my home looking better than it was before. Wayne is the man and I can't thank him enough he will get all my HVAC work moving forward!

We understood that we were working with a small family-owned company that did not operate 24/7, but after many calls over the course of a year, our calls have not been returned. Therefore, we were not able to use our service contract. Considering the great work they did when they did respond, this has been very disappointing.

I had two heat pumps installed about 3 years ago. I've had issues with the units that were mostly…read moreresolved over time. However, the rudeness of the receptionist( Joan) never resolved. Every time I called for either regular spring and winter maintenance or any repair I've had to deal with the worst customer service by this same woman. I've repeatedly told people from Pipco about this. I was told I could request to speak to other office people. That worked once or twice but most times I was left to deal with an incompetent woman who consistently made errors and blamed the errors on me. The final straw was when she gave me a number to confirm my maintenance appointment and I asked if this was a new procedure. She claimed she was confirming my number. I told her I know my number and that she was confused. I was polite and respectful. She went on a tirade. I repeatedly asked Joan to please stop. She then rudely said have a nice day and hung up on me. I called Brian who is the person who gave me my estimate years ago to alert him so he could do something. He responded, " I don't know what to say." Then he went silent. Perhaps he could have apologized but he didn't. I asked him to cancel my appointment and that was when I knew I'd never use Pipco again. Beware of the treatment you'll receive after you sign the contract and try to deal with Pipco for the maintenance. I'm switching to Perry Hall Heating and Cooling in the future. The receptionist who took my call ( Lisa) was polite, efficient and respectful. Make your decision carefully about your heating and cooling needs.

This man will hustle and break his back to earn your business and build a relationship with his customers. He takes pride in his work. I cannot recommend this place enough. On a Friday afternoon, I reached out to ~5-7 vendors to assess a broken HVAC in a DC condo. Ricardo was able to come out IMMEDIATELY at 8PM on a Friday night. He did a quick dusting of the unit which hadn't been serviced in a while and even went to the roof as a part of his diagnosis. After sticking around for a couple hours trying to find the source of the problem, I was mentally preparing myself to pay a diagnosis and service fee, but there was no such thing. What signaled to me Ricardo was top notch was the fact that this man lives in Baltimore, easily a 50-minute commute from where I was in DC. He didn't leave until I was satisfied with his work until 930PM on a FRIDAY night. This type of service is difficult if not impossible to find. Ricardo patiently explained what the problem was, why I wouldn't have working AC after he would leave, and what my options were. He was very transparent with pricing, sent over a couple of quotes, and laid out what install schedules would look like depending on which manufacturer I went with. He and his team came in Tuesday and the install lasted about 7 hours. Fully working AC in less than 2 business days at a reasonable and competitive price. You cannot beat that.

You really can't beat the quality of small, family-owned businesses. It's no surprise they've been in business for 75 years. The next time I need service, I won't hesitate to call Chason. I can also confidently say they'll be my first recommendation to any friends/family that require work. Thank you Steve!
