“We just got our boiler serviced by Pat from Cosyhome Heating and we are very satisfied with the service provided which was prompt and efficient and no mess left behind. He was very thorough, making sure the job was done right, and he gave us a full boiler efficiency report after. The boiler is running smoothly since the service has been performed and it was great to get an efficiency report as part of the service.”
Brendan O’Gorman, Turloughmore


“I noticed our boiler was making some strange noises each time it started up lately. A friend recommened me to get our boiler serviced by Pat from Cosyhome Heating. He came in and figured out the issues, and spent time making sure the job was done right. Our boiler is running great since. Could not recommend Pat highly enough!”
