We purchased a home with a 10 year old furnace so we needed a company to service the system and install a humidifier. They were great. Showed up on time and kept me informed all along the way. When the serviceman was installing the humidifier he found a problem with a plumbing connection on the Hot Water heater and ran to Home Depot and sweated on a new fitting to fix the issue. That could have been a big issue if it had not been detected. When he was finished, he went out of his way to make sure we understood the operation of the unit, what he had done and type of wear and tear he noticed on the furnace. He tightened the anchor bolts on the motor which got rid of a noisy squeek He checked the HVAC system and cleaned the furnace and we were VERY pleased with the service and will keep them as our servicing company. As he was leaving I tried to give him a tip, but he said that while he appreciated the gesture, their company policy was not to accept tips. Goes a long way with their credibility as a company and his as a technician for them. While we were out of town last week the furnace quit working and my daughter discovered it. They were able to send someone over the next morning to fix the issues which turned out to be the igniter on the 10 year old system. Great response. We used another company at our previous house and this one beats them cold.
