What is a Gas Boiler Installation Service?

A gas boiler installation involves the professional setup and configuration of a new gas boiler system in a residential or commercial property. This essential service ensures that the boiler is correctly and safely installed, adhering to local building codes and safety standards. The process typically begins with a consultation to assess the property's specific heating needs and preferences, followed by the selection of an appropriate boiler type and size. Experienced technicians then carry out the installation, connecting the boiler to the gas supply, water lines, and venting system, ensuring proper combustion air supply for optimal performance and safety.

Plumbing leak detection

“Farrell was easy and helpful to use. He returned my call in the timeframe he stated when checking his availability and arrived on the job earlier than quoted which was great. He was knowledgeable and went out of his way to explain what the issue was. Look forward to using Farrell again in the future!”
