Q&A
What are the most common HVAC problems you see in Lake in the Hills homes, and how do you fix them?
Here in Lake in the Hills, we frequently help homeowners with issues like dirty condenser coils and clogged air filters, which restrict airflow and force your system to work harder. For these common problems, our maintenance service includes a thorough inspection, cleaning of the outdoor condenser coil, and replacement of the air filter. We also check the entire system for proper airflow and refrigerant levels. Addressing these simple issues proactively during a seasonal tune-up can prevent more costly repairs and improve your system's efficiency and lifespan.
Do you handle both residential and commercial HVAC installations?
Yes, absolutely. Since our founding in 1983, we've built a strong reputation serving both residential and commercial clients across the region. For homeowners, we install and replace furnaces, air conditioners, and complete HVAC systems. For our commercial clients—including grocery stores, schools, churches, and factories—we manage larger-scale installations, custom ductwork design, and complex zoning systems. This dual expertise means we have the knowledge and resources to handle projects of any size, from a single-family home in Lake in the Hills to a new commercial building.
What is involved in your HVAC system maintenance service?
Our maintenance service is a comprehensive check-up designed to keep your system running smoothly and efficiently. It includes inspecting electrical connections, testing system controls and safety devices, cleaning critical components like the evaporator and condenser coils, checking refrigerant levels, lubricating moving parts, and replacing your air filter. We also perform a thorough airflow analysis and check the heat exchanger for safety. This proactive care helps catch small issues before they become big problems, maintains your manufacturer's warranty, and can significantly reduce your energy bills.
