The team at H&M were fantastic to work with. Very responsive on coming out and giving an estimate, they gave a frank opinion on what would work for our home and were patient with our questions. They even arranged to do the replacement the same day as my neighbor for convenience. Their team completed the work over the course of one day, were extremely respectful of our home and covid protocols, tested the equipment and answered any questions before leaving, and called to follow up and ensure satisfaction. Fantastic experience!

Exceptional company. I called them when I was in need of someone really good to do a time sensitive repair job. Not only was Ivan incredibly responsive, but his workers were prompt, professional, and their services were affordable. While I hope not to need them again anytime soon, I will definitely be using them for all of my future HVAC needs. I cannot recommend strongly enough.
