It can be difficult to know whether to repair an aging unit or invest in a full replacement. While a simple repair might seem more cost-effective upfront, a new system can offer substantial long-term savings and reliability. Look for these common warning signs that indicate it's time to consider a replacement:
We believe a successful installation is built on a foundation of precision, expertise, and clear communication. Our process is designed to be seamless and stress-free, ensuring your home is treated with respect and your new system is installed to the highest industry standards.
Our process begins with a thorough consultation to understand your comfort needs, budget, and any specific concerns you have. Our technicians then perform a comprehensive evaluation of your home, including an analysis of your existing ductwork, insulation, and window quality. For new constructions, we work directly from your blueprints. We conduct a professional "load calculation" to determine the exact size and capacity of the system required for your home, ensuring it runs efficiently without being overworked or underpowered.
Based on our assessment, we present you with a curated selection of high-quality, energy-efficient HVAC systems that are perfectly suited for your home. We'll walk you through the benefits of different options, such as high-efficiency furnaces, versatile heat pumps, or ductless mini-split systems, explaining SEER2 (Seasonal Energy Efficiency Ratio 2) and AFUE (Annual Fuel Utilization Efficiency) ratings so you can make an informed decision.
Our certified and experienced technicians handle every aspect of the installation with meticulous care. For replacements, we begin by safely decommissioning and removing your old unit. We then expertly install the new system, ensuring all electrical connections, refrigerant lines, and ductwork transitions are secure and compliant with all South Hill and Washington state codes. We protect your home throughout the process, using drop cloths and cleaning up our work area completely.
Once the physical installation is complete, we don’t just turn it on and leave. We initiate a detailed commissioning process to test and calibrate every component. This includes checking refrigerant pressure, testing airflow, verifying thermostat accuracy, and running a full system diagnostic to confirm it is operating at peak performance and efficiency.
We conclude every installation by walking you through your new system. We’ll show you how to operate the thermostat, explain any advanced features, and provide essential maintenance tips, such as when and how to change the air filter. We ensure you are completely comfortable and confident with your new HVAC system before we consider the job finished.
