I would give more stars if I could. I’ve worked with 5–6 different HVAC companies, and it’s not even fair to compare them to On the Mark. From the initial consultation—which lasted over an hour and taught me more about my system than I’d ever known—to the installation of our new heat pump and furnace, the service was a true 10/10.

On the Mark installed a new AC and did a great job in the installation, as well as guiding me through the process. Chris and Alex did the installation and were very professional, knowledgeable, and friendly! Would definitely recommend On the Mark for any HVAC needs/services.

I’ve used On The Mark a few times for minor repairs, but this summer I had them out for a full system replacement, and they did a fantastic job. I’ve been waiting to post this as I wanted to give a little time to also use the furnace.

ARE YOU READY FOR AN AC REPLACEMENT?
There often isn’t a simple answer. Your heating and cooling system may be working. However, replacing it can be more affordable in the long term, especially when you notice the following signs:
Loud and/or unusual noises from equipment
Inconsistent temperatures throughout your home
Decreased efficiency, especially for a 15+ year old system
Constant running, or frequent cycling on and off
High repair costs
These issues are good reasons to consider a new AC system. Reach out to us today to learn about your options.
