I have used ECM for many years being a resident of Century Village in Boca. In 2017 I needed to replace my 2 ton AC. I got three prices, and choose ECM. The other tow companies were lower but WERE NOT pulling a Palm Beach County Permit, was not upgrading the electrical, and was not tying down the unit outside on the concrete slab for hurricane protection. The two repair guys were fabulous, very clean, gentleman and completed their job in a professional manner. They showed us how to use the new thermostat and dehumidifier. We did have a minor issue on the outside piece of concrete and that was corrected today. The contractor that came was excellent and took care of the issue. I will renew my annual contract with ECM in 2018.
