A company I relied on to service my unit kept changing appointments on me! It messed with my work schedule badly! So finally after calling a few companies, it was McQuerry's 24Hr.'s very pleasant and professional receptionist that answered right away, let me know exactly that they had no problem working around my schedule and finally serviced my furnace! Comes to find out that my furnace was not safe to run due to very high carbon monoxide. In addition my furnace was not correctly installed and had been found to be unsafe for years! Within just a few hours, they pulled a permit, installed a new one, and provided me a unit replacement warranty PLUS a money back guarantee!!! Outstanding! My only complaint? I didn't find them sooner when I moved to Ballwin years ago!!! Thank you McQuerry! You saved me and my families life!!!

FAQs

What should the customer know about your pricing (e.g., discounts, fees)?
yes (see above)
What is your typical process for working with a new customer?
For service, we schedule an appointment window (which we strictly adhere to) and then provide a complete price for service. For replacement, we do a home energy audit and engineering analysis (at no charge) then provide an upfront cost. For duct cleaning, we provide a cost based on openings in the hvac system.
What education and/or training do you have that relates to your work?
Ron holds 2 St. Louis County licenses (which require 12 continuing ed. credits each) and is Nate certified (requiring Nate education classes). All of our technicians are also Nate certified.
