When it comes to change the cubs have seen their share. We have been in the Wrigleyville area repairing furnaces and heaters since 1966. Not much has changed at Citywide Supply & Service. We are still your local furnace repair service company for all your heating and cooling needs. We are still Wrigleyville’s most affordable heater repair company. We are still on a flat rate pricing system which means you will not pay for a contractor to chase parts or time and money replacing parts only to tell you that there is another problem. We charge a diagnostic fee which includes a one time flat rate price to repair your furnace. If you make the repair we waive the diagnostic fee. 
You’ll be happy to know that all our repair are guaranteed in writing for a minimum of 2 years. We are firm believers in making a repair last with high quality parts not the cheap aftermarket parts that many companies are using today. That is how we can offer warranties on our repairs that other do not. When it comes to quility repairs at affordable prices we wrote the book. Give us a call and schedule your appointment today.
