Grissom Heat & Air - Knoxville's Trusted HVAC Services

In our area, we frequently see AC capacitor failures on hot, humid days and air handler fan issues that stop air circulation. These are urgent repairs we handle daily. As a local, family-run business, we offer 24/7 emergency service and prioritize getting a technician to your Knoxville home as quickly as possible, often the same day, to restore your comfort.

Knoxville's pollen and humidity can affect indoor air. We offer solutions like installing or servicing Honeywell air filtration systems, which capture allergens and particles. We also provide thorough duct inspection, cleaning, and sealing services to prevent dust and contaminants from circulating through your home, creating a cleaner, healthier environment for your family.

Choosing a new system involves considering your home's size, existing ductwork, and energy efficiency goals. With over 39 years of experience, we provide a detailed consultation to assess your needs. We work with reliable brands like Goodman and Amana to offer options that balance performance, durability, and operating costs, ensuring you get a system tailored for long-term comfort and savings.
