Commercial Furnace Repair


Furnace services are urgent. Contact your local Hous Air HVAC Service if you notice any of these common signs of furnace failure:


The unit won’t turn on or off

The pilot light is out

The unit is making unusual noises

The unit is producing strange smells (gas leaks require emergency evacuation and service)

The burners won’t light

The blower runs constantly

Our service professionals will fully inspect your unit to ensure that all possible repair needs are addressed. Depending on the type of issue, you can expect our team to perform diagnostic tests, fix loose or faulty wiring, repair or replace broken parts, clean external parts or clogged drains, or replace the filter.


To help prevent these common furnace problems and further extend the life of your system, we recommend scheduling annual furnace maintenance. Regular maintenance services can help you to get ahead of problems, plan for future repairs or replacement, and extend the life span of your unit.

Commercial Furnace Replacement

We recommend furnace replacement when units are damaged beyond repair, are past their expected life span, or pose a safety hazard (for example, they are at risk of springing a gas leak). Other signs of impending replacement include:


Old age (15+ years)

Frequent, extensive, or costly repairs

Decreased efficiency

Aside from these urgent replacement situations, a new unit may also be a beneficial investment for improving indoor air quality and business operation costs. An upgraded, higher-efficiency commercial furnace can significantly improve the comfort of your building environment and possibly save you money on energy bills. Additionally, tax and rebate incentives may be available for these newer units.


Our service professionals will help you weigh all options and costs before choosing a replacement furnace system.

Why is my commercial furnace blowing cold air?

Possible issues include:


A faulty or incorrectly set thermostat

A broken ignitor or pilot light

A lack of fuel

An issue with airflow due to filters or ductwork

Depending on your unit size and location, troubleshooting can be difficult and dangerous. To avoid more costly repairs, schedule commercial furnace service with our qualified experts.

Why is my commercial furnace not maintaining heat temperature?

Occasionally this issue can be quickly resolved by cleaning or recalibrating your thermostat.

We recommend choosing professional service for all troubleshooting and maintenance tasks.
