Q&A

Why is my home in Salisbury so stuffy, and how can Marathon Service Co help improve indoor air quality?

The Eastern Shore's high humidity can make homes feel stuffy and exacerbate allergens. We improve indoor air quality by installing whole-house dehumidifiers, advanced air filtration systems, and performing thorough duct cleaning to remove accumulated dust, pollen, and mold spores, creating a fresher, healthier living environment for your family.

What can be done about uneven cooling, especially between the upstairs and downstairs of my home?

Uneven temperatures are common in Salisbury's older homes or those with single-zone systems. We solve this by performing a detailed home comfort analysis. Solutions may include zoning system installation with multiple thermostats, ductwork modifications to balance airflow, or recommending and installing a properly sized, high-efficiency HVAC system designed for your home's specific layout and needs.

How does preventative maintenance from a local company like Marathon Service Co benefit my Salisbury home's HVAC system?

Our local climate puts extra strain on AC units and furnaces. Our preventative maintenance program includes a comprehensive check-up: cleaning coils, checking refrigerant levels, lubricating parts, and inspecting electrical connections. This proactive care improves efficiency, prevents costly mid-summer breakdowns, extends your system's lifespan, and ensures it operates safely and effectively throughout Maryland's varying seasons.
