"Joyce installed the system with new duct work, zoning, dampers, new furnace, A/C, and thermostats. They knew exactly what they were doing, installing the system as described and on time. During the 4 days of installation, management dropped by to make sure it was going well. They had all the right equipment and everything went as planned. No snags. These guys are real pros. I'd recommend them to anyone. I love my new Lennox HVAC system. My home finally is finally comfortable. The new system is also whisper quiet."

"We installed a Fujitsu mini-split A/C and heat pump because installing duct work was not an option. The entire process from getting a quote to completing the installation couldn't have been any better. Joe went over the full scope of the project including the ramifications if any additional work was needed. I don't think one could find a better HVAC company than Airco!"

"My central AC unit has been broken for several years. intermittently working during hot summers. I've had several HVAC companies come to diagnose and all of them told me different things: replace the whole system, new lines, etc. potentially costing tens of thousands of dollars. So I decided to troubleshoot by myself and pinpointed the issue: the filter dryer needed to be replaced. No company wanted to do this small job. I called Emerald HVAC and told them about my issue, they sent in José, who diagnosed the issue to be what I said. He replaced the filter dryer and the AC unit works perfectly now after several years! In short, Emerald HVAC will be my first choice for any HVAC work in the future. They are honest, professional, and reasonably priced. I recommend them without reservation!"
