Here are our current offers to save you money on home plumbing, heating and cooling service, replacement and repairs. To take advantage of these specials, just call us at 815-455-7000 to request an appointment and mention the offer.

Free Second Opinion on Air Conditioning Systems

If you are having problems with your air conditioner, many contractors will leave you feeling you only have one option. Replace your equipment. That is why we offer free second opinions. In far too many cases, customers are told they need a new compressor or system when in fact it is simply a wiring issue, burned contactor, failed capacitor, or other inexpensive repairs. To schedule, just mention this offer and present the arriving technician with the findings from the other contractor.

Mention or present this offer at the time of service to receive $50 off any repair to your air conditioning system.
