Common Questions
My energy bills in Dundalk seem higher than usual. Can you help?
Absolutely. High energy bills are a common concern in our area, often caused by an aging or inefficient HVAC system. At THMC, we perform a thorough inspection to identify issues like refrigerant leaks, poor insulation around ductwork, or a system that's simply working too hard. We'll explain our findings and recommend practical solutions, which could range from a targeted repair to a more efficient system installation, always focusing on improving your home's comfort and lowering those monthly costs.
What's included in your HVAC maintenance service?
Our maintenance service is designed to keep your system running smoothly and catch small issues before they become big problems. We perform a comprehensive check that includes cleaning coils, checking refrigerant levels, inspecting electrical connections, testing system controls, and lubricating moving parts. For Dundalk homeowners, we pay special attention to airflow and duct connections, which are key factors in preventing uneven cooling and heating between rooms—a frequent local issue.
How do I know if I need an HVAC repair or a full system replacement?
This is a common question. As your local technician, I'll give you a clear, honest assessment. We consider the age of your system, the frequency and cost of recent repairs, and its current efficiency. If repairs are frequent and the system is over 10-15 years old, a replacement is often more cost-effective in the long run. We'll walk you through the options and our available deals, ensuring you have the information to make the best decision for your Dundalk home and budget.
