Equipment fails at inconvenient times. No heat on the coldest night of the year and no cooling during a heat advisory are both serious problems, and for households with infants, elderly residents or anyone with a respiratory condition they are more than an inconvenience.

Call the number on this page and describe what the system is doing. We will tell you what you can check yourself — a tripped breaker, a float switch, a thermostat battery, a filter so loaded the system has iced over — because some of these you can clear yourself in five minutes without paying anybody.

Call (513) 667-8484 and tell us what the system is doing. If you reach voicemail, leave your name, address and the problem, or send a service request online and choose "As soon as possible" so it is the first thing we see.
