24-Hour Emergency Service

Your emergencies don’t take nights or weekends off – so why should we?

Emergencies don’t always wait for regular business hours. That’s why Pass One Hour offers 24-Hour Emergency Service, seven days a week. Whether it’s a furnace breakdown in the middle of a cold winter night or an air conditioning malfunction in the middle of a sweltering July weekend, we can help

Just call (618) 427-2420 day or night to speak to a Pass One Hour Customer Service Representative. If we can’t solve your problem over the phone, a skilled technician will be dispatched immediately to your home to help restore your home’s maximum comfort.

“Jeff is the best! He truly is so well versed in his craft and answered all of my questions. He recommended upgrades based on our needs and even pointed out issues with our dryer vent we hadn’t noticed before.”

“Ryan was on time and we throughly discussed what he would be doing during his inspection and the initial cost. He presented a range of other possible costs for repairs following his inspection and explained he would discuss this with me before proceeding with any other work. He was very detail oriented and knowledgable. I was impressed enough to enroll in their maintenance program.”

“Ryan got the part my heater needed installed quickly and properly! And I love that this company sends you a text with a picture of your technician. That is a measure I appreciate them taking for my peace of mind.”

“Trent and Ryan did an amazing job installing our new unit! Trent was the inside man while Ryan had the dirty job outside. They really seemed to love what they do and are very knowledgeable. I would highly recommend them! 10 out 10 experience”
