Frequently Asked Questions

Spring and Summer HVAC Maintenance

When should I schedule spring AC maintenance in the Black Hills?
Book it in March or April, before the heat sets in, so your system is ready when summer temperatures climb. Waiting until the first hot week means competing with everyone else for an appointment.
A tune up covers cleaning or replacing air filters, checking refrigerant levels, inspecting the condenser coil, testing electrical connections, and confirming the thermostat reads accurately. Our NATE certified technicians handle every step.
Replace it every 60 to 90 days during heavy use months. Homes with pets or systems that run constantly should check more often.
Yes. Dirty coils and clogged filters force the system to work harder, which raises your bill and shortens the equipment’s life. A yearly tune up keeps energy costs down.
Watch for uneven cooling, weak airflow, unusual noises, warm air from the vents, or the system turning on and off too quickly. Any of these are worth a service call before you rely on the system through the hottest months at Pactola, in Hermosa and in Hot Springs areas.

Well Water and Filtration

How do I know if my well water needs treatment?
Look for a rotten egg smell, rust colored staining on fixtures, cloudy water, or a chalky residue building up around faucets and shower heads. Hard water is common across this region given the mineral content of local groundwater.
A softener addresses hardness caused by calcium and magnesium. A filtration system targets specific contaminants like iron, sulfur, or sediment. Many homes benefit from running both together.
Yes. We test your water first to see exactly what is in it. No two wells are the same, even for neighbors on the same road.
Yes. Scale buildup from hard water restricts flow, damages water heaters, and can reduce the efficiency of HVAC components that use water. Softening or filtration usually pays for itself over the life of the systems it protects.
It depends on the media type and how much water your household uses. Most systems need a filter change or media swap every 6 to 12 months. We can put together a schedule during a consultation.
