You may need a new system if:
- The unit is past its lifespan. Age is one of the biggest factors to consider. Most commercial units last 15-18 years. Systems that are 10-15 years old may need to be replaced.
- Repairs are frequent and costly. Does your unit need frequent repairs? It may be time for a commercial air conditioning replacement. A new installation may be less expensive in the long run, especially if your system is older.
- Your utility bills are higher. Older or malfunctioning units are less efficient. A spike in energy costs may be a sign that it’s time for a new system.
- Strange sounds and odors. These are both indications that you need commercial air conditioner replacement. Odd smells may indicate mold or contaminants in the system, which could pose a health risk.
Still not sure whether you need to replace your HVAC? Call us to schedule a visit. We’ll inspect your unit and make recommendations on whether you need replacement.
