Questions and Answers
As a Silex homeowner, my AC unit keeps freezing up or the outside coils get dirty. What can you do to fix and prevent this?
We see these common issues often in our local climate. A frozen evaporator coil or dirty condenser coil usually points to airflow problems or low refrigerant. Our repair service starts with a thorough diagnosis to identify the root cause—whether it's a clogged filter, failing blower motor, or a leak. For prevention, our maintenance program includes cleaning the condenser coils, checking refrigerant levels, and ensuring all components are functioning properly to keep your system running efficiently and avoid costly breakdowns.
Do you handle excavation work for projects like sewer line installation or land clearing, or is your focus only on HVAC?
We provide full-site service. In addition to our HVAC and plumbing expertise, we operate our own backhoe and skid loader for excavation projects. This allows us to manage jobs from start to finish, whether it's trench digging for a new sewer line, preparing land for construction, or performing the gas and water pipe installations that come after. Having all these services under one roof ensures coordinated, efficient work for our clients.
My water heater needs replacing. Do you offer financing for larger projects like this?
Yes, we understand that major replacements like a water heater or HVAC system are significant investments. We offer financing options to help make these necessary services more manageable for our customers. During your consultation, we can discuss the available plans to find one that fits your budget, allowing you to get the reliable hot water or climate control your home needs without delay.
