Resolving a Tiny Issue at No Charge for a Loyal Customer

Problem: Lisa M. faced an issue when the pilot light on her furnace went out, and the usual person who handled it couldn't reignite it, leading her to fear she might need a new furnace. She decided to give Cooper Heating & Cooling a call for help!

Solution: Connor from Cooper arrived on time, professionally addressed the issue by successfully lighting the pilot light, and replaced an outdated piece of copper without upselling unnecessary services. He advised Lisa to start saving for a furnace replacement due to its age, earning high praise for exceptional customer service.

"I HIGHLY RECOMMEND this company."

I called Cooper since my pilot light went out on my furnace and the guy that normally lights it for me could not get it to light. I feared the worst (a new furnace was needed). Connor arrived on time and was extremely nice and professional. He found the problem, was able to light the pilot, and replaced a VERY old piece of copper. I am EXTREMELY happy with the service he provided. He did not try to upsell me things I did not need, but did suggest I start saving money to replace my 18 yr old furnace. I HIGHLY RECOMMEND this company. Kudos to Connor for amazing customer service!!
