Mon-Clair Heating & Cooling LLC was amazing to work with. They were there within hours of us calling to report that our AC wasn't working. Nick diagnosed our issue & got us an estimate quickly. After we told him we would like to proceed he promptly ordered the new unit & as soon as it was received, he called to schedule the install. We were very pleased with the quality of the work, the attention we received, the speed & accuracy of the work & the amazing customer service. Overall, we were extremely satisfied with the work. We will ALWAYS use them with any heating & cooling needs we have from here on out & highly recommend Mon-Clair Heating & Cooling LLC. I can't speak highly enough about them & Nick.
