New AC condensers are shipped from the manufacturer with refrigerant already inside the system. This factory charge is intended to support a standard refrigerant line length, typically around 15 feet, which works for many straightforward installations.
That said, many homes require longer line sets due to layout, attic placement, multi-story construction, or the distance between the outdoor condenser and indoor air handler. When the line set exceeds the factory standard, additional refrigerant must be added to ensure proper cooling, efficiency, and system reliability.
Incorrect refrigerant levels can cause a range of issues, including reduced cooling capacity, higher energy costs, compressor strain, and long-term damage to the system. Too little refrigerant can prevent your AC from keeping up during hot weather, while too much can lead to pressure problems and component failure.
This is why professional installation matters. At Mainstream Electric, Heating, Cooling & Plumbing, our licensed HVAC technicians measure, adjust, and verify refrigerant levels during every AC installation. We follow manufacturer specifications and real-world performance testing to ensure your system is properly charged, balanced, and ready to perform efficiently from day one.
Heating and cooling emergencies rarely happen at a convenient time. When your furnace stops working in freezing temperatures or your AC fails during a heat wave, fast service matters.
Mainstream offers 24/7 emergency HVAC repair in Spokane Valley for urgent issues such as:
Our technicians respond quickly, explain your options clearly, and provide upfront pricing before repairs begin.
An HVAC emergency occurs when your system fails in a way that threatens your comfort, safety, or home. In Spokane, that often means no heat during freezing temperatures or no cooling during extreme summer heat.
Other urgent situations include system shutdowns that will not restart, electrical burning smells, gas odors, sparks, unusual noises, or frozen components that prevent airflow. These issues should not be ignored.
Mainstream provides fast, professional emergency HVAC repair to restore safe and reliable operation as quickly as possible. Our licensed technicians diagnose the issue, explain your options clearly, and complete repairs with precision and care.
The most effective way to avoid emergency HVAC repairs is through routine maintenance. Small issues like worn components, airflow restrictions, or electrical wear often go unnoticed until your system fails during extreme heat or freezing temperatures.
Mainstream’s Care Club provides scheduled inspections, priority service, and professional tune-ups designed to keep your heating and cooling systems running reliably year-round. Our licensed technicians identify problems early, improve system performance, and help extend the life of your equipment.
Preventive maintenance not only reduces the likelihood of unexpected breakdowns, it protects your comfort and gives you confidence when Spokane’s weather puts your HVAC system to the test.
An oversized unit can short cycle and waste energy, while an undersized unit may struggle to cool your home. We perform detailed load calculations to determine the right system capacity for your space. Correct sizing improves efficiency, extends system lifespan, and ensures consistent indoor comfort.
Standard AC replacements are typically completed within one day. Projects involving new ductwork, electrical upgrades, or first-time installations may require additional time. Our team communicates timelines clearly so you know what to expect from start to finish.
