I first hired them a few years ago to replace my AC system, and the experience was…read moreoutstanding--professional work, fair pricing, and everything done right the first time. Since then, Brian has become my go‑to HVAC team for anything related to my rental property. What really sets Droptine HVAC apart is their honesty and integrity. Over the past few years, they've come out to my property multiple times to troubleshoot issues for my tenant, and not once did they charge me for those visits. In a world where quick upsells and unnecessary charges are common, this kind of honesty is extremely rare. They consistently show up on time, explain everything clearly, and genuinely want to help rather than profit from every call. It's hard to find service professionals you can trust--Droptine HVAC is one of those rare finds. If you're looking for knowledgeable, reliable, and truly honest HVAC service, look no further. I recommend them wholeheartedly.

Brian and the guys at Droptine did a phenomenal job replacing my evaporator coil. Honest team and…read moregood family-run business. He was really easy to work with from the start, always super informative and never pushy. He always got back to me quickly (I had some parallel home warranty things I was navigating at the same time and he also helped explain what was going on), and showed up when he said he would. That kind of reliability is hard to find! Overall, a smooth experience and I will 100% use them again, and recommend to all my friends. You should hire them too!

Explained to him my family had no heat whatsoever and I have two elders we are taking care of. Without hesitation, he came out asap and took care of the issue. Not only did he fix the problem, he also took the time to check my whole system to ensure all is running well and gave recommendations to prevent any more mishaps. Great customer service, great communication, very professional, most of all, very affordable. It's rare nowadays to get all those combinations. I found my AC/Heating guy. A+ Service, highly recommend.

On The Mark Heating and AC is my go to for all my climate control needs. I have known the owner for…read morealmost 2 decades, since the inception of this business. He is fast, he is honest and he won't give you the runaround. If he can't get to it for a few days or a week, he'll say so. He usually shows up within the hour when I call him. His prices are as reasonable as you would expect and even less. Sometimes it surprises me how little I pay him for the work he does for me. Once again I can't say enough good about this business, it's helped my family maintain our home for years and I hope you give him a chance if you have any need. If I could give him 10 Stars, I would.

Highly recommend this company and my best wishes to Alex and Nima.

They were the only local HVAC company that would even talk to me when I wanted to use my home warranty to help pay for costs, and that alone convinced me that this is a company that genuinely cares and wants to do right by their customer. It's been a pleasure, and I'm sure it will continue to be one. Thanks guys!
