Quick Diagnosis: Signs Your Commercial Heater or Furnace Needs Service

Uneven or Insufficient Heating in Workspaces

In short, when heating fails to be consistent, it means the system is inefficient, failing components are causing strain, and your facility is wasting energy. Not only is it not optimal for your employees and customers inside the building, it is a direct sign that there is an issue with at least one of the components of your HVAC system.

Strange Noises or Odors Coming from the Unit

When your unit starts producing unusual sounds—such as grinding, screeching, or loud banging—it typically signals a failing motor, loose fan belt, or damaged compressor. These mechanical issues create friction and excessive wear, which can quickly lead to an expensive breakdown if ignored. Potential mold or mildew growth inside the coil or drain pan is the main reason why a smell would be coming from the unit. This is an immediate red flag and should not be ignored.

Inconsistent Thermostat Readings

Inconsistent thermostat readings are a potentially big issue that does not only stem from the thermostat being faulty. There could be an issue with poor placement of the thermostat, faulty sensors, or wiring disconnected. This likely leads to wasted energy and higher costs from the HVAC system.

Increased Energy Bills or Reduced Efficiency

Increased energy bills are not only an issue to the wallet, it likely means the system is running less efficiently and spending significantly more time to reach the desired temperature. There can be many reasons for this such as a refrigerant issue, dirty air filter, clogged coils, or poor insulation. If you notice jumps in energy consumption without changing the temperature much, if can be a clear sign that one of these issues may be occuring.

Frequent Cycling or Unexpected Shutdowns

Short cycling of an HVAC system is a critical symptom revealing that your system is failing at a critical step. Refrigerant is a main culprit with these issues, whether the refrigerant is not charged correctly, or if there is a leak and there is no refrigerant left at all.

Our licensed, insured, and EPA-certified team will diagnose the issue and explain your options clearly. Most repairs can be completed during the first visit, and we back our work with a 12-month warranty (unless otherwise noted). Keep your business warm and running smoothly.

New High-Efficiency Commercial HVAC Installation & Replacement

Most HVAC systems have a lifetime of 10 to 20 years. As your equipment gets older, its efficiency can decrease dramatically. You may notice that it gets noisier and needs commercial repairs more often. When a unit begins to show its age, you can either repair or replace it.

Because heating and air conditioning technology improves over time, a unit designed with newer, more energy-efficient equipment makes sense, especially if your system is 15 or more years old. We install all major makes and models.
