Review: I woke up to a cold house on a single digit temperature day in January. Out of need for a quick response I googled HVAC repair near me. I chose On The Mark because they were geographically close by and were not a big sponsored company. I was happy to know that a service man could be there within a few hours. Unfortunately our 20+ year old furnace was not repairable. We managed to stay warm enough with space heaters until the salesman could show us our replacement options. He was very methodical in assessing and sizing a new unit for our house. We were happy to know that a new furnace could be installed next day, and they even offered us space heaters to hold us over. All personnel we have dealt with at On The Mark including call center, service technicians, sales, the and even Mark himself were very responsive and professional. We would highly recommend On the Mark.

Review: Chris was awesome. He was very knowledgeable and helpful in checking out and addressing the issues with my furnace and thermostat. I felt like he made reasonable recommendations and the estimate I received was reasonable too. I feel like I’m in good hands with this company and I’m relieved that I purchased a subscription service with them, so if I have future issues or questions, then I have a reliable source of support I can call for assistance.

Review: My cousin used On the mark at his company and recommended On the mark to install an air conditioner and furnace in my home. I am a senior and I Don’t know anything about the equipment so they set me up with a service maintenance plan to come out for checkups. Staff and sales rep and installers all did a good job.
