"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"My new HVAC system failed at beginning of summer . They worked with me to fix and resolve the problem . The last visit with their technician Hunter went well. He took the time to explain and show us the different filters that we need to monitor. Thank you Hunter , Tyler and AC techs. I canâ t live without AC. Otherwise I drip with sweat . No Florida retirement for me ."

"Woke to a chilly home stemming from a heat-pump issue. Posted my repair service need on Angi and within minutes, received a text and phone call from HOFFMAN MECHANICAL, who was able to come out same day and got my Lennox unit up and running again at a fair cost for both parts and the weekend/after hours service call fee. I would use them again without hesitation, and I am happy to highly recommend this company!"

"We were Extremely Satisfied with the Quality of Workmanship and the Product we Decided to go with for HVAC Install... At the same time we had Central Air added, we were tired of window units... Plus, it is Less Expensive to have Both Installed Together!! We Have Really Noticed a Big Difference in how the Rooms in the House are Much More Evenly Heated and How Much More the Heat is Felt while Moving from Room to Room, From Floor to Ceiling!!! The House Has Never Felt So Good!!! A 10+ Star Rating in Our View from the Install and Service from Connelly Heating Air Conditioning!!! In Addition, We Saved over $1,000. with Connelly Heating Air with Bids from 3 other Companies!!! Thank You, Jean Tony S. in Manheim, PA."

"Stahls Mechanical is a top notch company and I would highly recommend them for any HVAC/plumbing work you have. My a/c went out and they were out within a day and had me up and running again in no time and at a reasonable price. Staff was friendly and knowledgable. Thank you Stahl’s and team for all of your help! Will definitely use you again in the future!!"
