Have to Say

“Prompt service call when HVAC system quit working in 32 year old home and then selection with help from Siemer sales to select new furnace and AC system components at a reasonable price. 4 days later install crew of 3 arrived and immediately put down floor coverings to protect my wood flooring, I was involved in many HVAC type projects as a engineer and from me asking tech questions and to the 3 installers working as a team I could not have expected anything better. I looked at the black iron, PVC and refrigerant piping and it was perfect. Controls install/ new thermostat along with electrical breaker change out inspect found no faults. Outside AC unit pad was level and all wall penetrations were sealed, again great work. Install crew reviewed with me all new equipment and how to operate system again great job. Install had a checklist they performed which they said was required for all Siemer projects – very professional.”
