Dominics HVAC Services | Top-Rated HVAC Repair in Portland, OR

Common signs include your AC running constantly without cooling effectively, ice forming on the refrigerant lines, and a noticeable hissing or bubbling sound near the indoor unit. Portland's temperature swings can stress older systems, making leaks more likely. It's important to address this quickly to prevent compressor failure.

For many Portland homes, upgrading your HVAC system's air filter to a higher MERV rating and considering the installation of a whole-house air purifier or UV light system can make a significant difference. Regular duct cleaning and ensuring proper ventilation are also key steps we recommend to combat local allergens and pollutants.

Given our wet springs and variable temperatures, the two most critical services are a pre-summer AC check to ensure it's ready for heat waves and a fall furnace inspection to guarantee safe, efficient operation through winter. This proactive maintenance helps prevent the most common emergency breakdowns we see locally.
