We are full-service heating and air conditioning company that provides residential and light commercial service, installation and maintenance. We truly believe that if we focus on helping people and treat others with respect, our customer's experience shall be an amazing one.

"poor customer service. service manager insulted me, called me derogatory names while defaming my character. when all I was looking for was for someone to right a wrong. I was actually looking forward to them coming to look at my furnace and was hoping to find a trusted company but was given the complete opposite of what I expected. first no one called me with an update, I had to call, then no one showed by 5pm after I waited patiently all day during their 8-5 window. finally at 5:10 i reached out again only to be met with an after hours line that couldn't help me at all. once I spoke to SM, he insulted me, called me derogatory names and defamed my character all because I was understandably upset for being "brushed off" by everyone I had come into contact the entire day and given excuse after excuse with no solution that was going to benefit me. Customer service and professionalism are lacking 100%"

"We had our master and hall baths completely gutted and rebuilt. We bid the project out to several companies, and DMV was immediately the most helpful. Pricing was very competitive. Luis and the team completed both bathrooms in about 6 weeks - and this was a full demo. The crew was extremely kind and courteous, and worked hard to minimize the mess and impact to our home. One weekend we had a party, and they helped make our home look like there wasn’t a major project in-progress! Craftsmanship was impeccable. The tile work in particular is beautiful - details I hadn’t even thought of were done for me. Like any job, we had some changes to scope (our choice), and some minor hiccups. They were extremely helpful navigating through scope changes, and more than fair on pricing. And on the minor hiccups, they made it extra clear that the job wouldn’t be wrapped until we were satisfied - and that’s what happened. Honestly this experience was a 10 out of 10, and I hope we can have them out for another project soon. Our bathrooms went from blight to bling in 6 weeks - I look forward to getting ready now!"

"Extremely disappointed with this company. They do not stand by their guarantees. Did install shower in one day. Was not provided with the shower head I ordered. Calking and trim work was very sloppy. Went through the shower wall into my bedroom, did sparkle wall and left it. Shower doors have leaked and was finally told six months later that there is nothing they can do to correct the issue. Originally quoted $24,000.00 for the walk on shower, eventually agreed to $11,500.00. Completely dissatisfied with my shower. Once they get their payment, they are done."
