Very professional and courteous installer who has been in the business for over 20 years. Helped me recently (Dec 2015) by installing new Aprilaire 600 humidifier, as well as couple of different Honeywell UV systems, and a larger external filter unit, into a very small and tightly packed townhome closet. He built a custom return box to be used with the new filter unit for our furnace. Since everything was very close together, furnace exhaust also had to be rerouted out of the way. He then made an additional electric outlet for the two UV systems that require power. While installing humidifier, he also shed light on the previous installers pitifuls and previous cleaners negligence (we found cigarette butt, drywall pieces, and other garbage and residue inside the supply box). This installation took almost all day (about 8 hours), but in the end everything that was requested was installed and working together. My girlfriend is happy and I am thankful to the installer and his crew for the work they have done and for being respectful to us and our home (placed tarps to protect our floors). Thank you and hope to do more business in the future!!
