Commercial Boilers Eugene

If you have any problems with or questions about your boiler then look no further. We are the regions specialists on all makes and models of boilers. With decades of service in the community, our outstanding customer service and technical ability has served some of the largest companies and institutions in the area.

Our team of technicians has in-depth knowledge of the current codes, emission standards, all other aspects of boiler/steam systems and their components. From the fuel line to the stack, we cover all your boiler and steam system needs.

We can assist you in system evaluations, installation planning, and design/layout drawings that meet precise specifications. We believe our job goes beyond the install and start up.

We develop relationships with building owners and their team of engineers and contractors to ensure proper operation and efficiency is maintained.

Modern technology is providing us with an abundance of highly efficient boilers to heat your building or produce a high volume of domestic hot water. Older boilers burn fuel at a rate of 50-70% efficiency and new models can burn at 85-100% efficiency. This effects your bottom line if you are letting money literally go up in smoke! If it is not economical for a new replacement unit to be installed, a precision tune-up and flu gas analysis will result in a more efficient boiler.

In the event of a boiler failure, our staff will do whatever they can to get you back online as soon as possible. Mechanical Heating and Air has the knowledge, experience, and commitment to provide quality and timely repair you need to resume operation. We can also provide rental boilers if needed.

Our class III boiler technicians are licensed to service and install the following systems:

Boiler Systems

The most efficient boilers on the market, condensing boilers and water heaters are able to achieve 98% efficiency. They are best suited to lower temperature applications and are most commonly used as a heating system and domestic hot water.

Condensing Boilers

These boilers are used for all hot water and heating applications. Most commonly used for radiant heating and domestic hot water.

When gas or oil is not available, electric boilers are used for heating and hot water applications.

All steam applications that require 250 degrees or pressure above 15psi require High Pressure Steam Boilers. They are most commonly used in processing facilities such as lumber mills and breweries.

All applications that require pressure below 15psi and temperatures under 250 degrees use Low Pressure Steam Boilers. They are most commonly used in large scale domestic hot water and heating.

Mechanical Heating and Air is capable of designing, installing, and servicing all steam and condensate systems. If your system has failed, leaking, or bypassing it can be costly. Our steam trap surveys, pump, Pressure Reducing Valves, and overall system inspections can spot problems before they arise and give you the confidence your system is running efficiently and safely.
