Alliance Mechanical | Licensed HVAC Repair in Charlotte, NC

We frequently help Charlotte residents with clogged air filters and air handler fan failures. A clogged filter restricts airflow, making your system work harder and increasing energy bills. We replace it and show you how to maintain it. For a failing air handler fan, which can stop cooling or heating entirely, we diagnose the cause—often a faulty motor or capacitor—and perform a precise repair to get your system running quietly and efficiently again.

Consider replacement if your system is over 10-15 years old, requires frequent repairs, or your energy bills are rising noticeably. We provide a straightforward assessment, comparing repair costs to the long-term savings and reliability of a new, efficient system. For Charlotte's humid summers, a modern system can also improve dehumidification and comfort. We'll explain your options so you can make an informed decision for your home.

Proper insulation helps maintain consistent temperatures year-round. In our climate, it keeps cool air inside during hot summers and retains heat in winter, reducing strain on your HVAC system and lowering energy costs. We assess your attic, walls, or crawl spaces and recommend the right insulation material and R-value for your home. This service complements your HVAC system, making your entire home more comfortable and efficient.
