When it comes to cooling in Clyde, the local conditions matter. Clyde's position in the Pigeon River valley between Canton and Waynesville means it shares the cold air drainage and moisture issues of both communities. Many homes here are older ranch-style builds from the 1960s–80s with original ductwork that has deteriorated over decades. The area's proximity to the river also creates higher humidity levels that strain HVAC dehumidification capacity, especially in crawl space homes common throughout Haywood County. Our AC technicians understand these Clyde-specific factors and size every repair and recommendation accordingly.

Why This Is the Most Important Thing You Can Do for Your HVAC

Changing your furnace filter is the single most impactful maintenance task a homeowner can do — and it takes less than 2 minutes. A clean filter improves airflow, reduces energy consumption by 5–15%, prevents frozen coils, protects the blower motor, and improves indoor air quality. A dirty filter does the opposite of all those things and can lead to expensive repairs. Despite this, the average American home goes 3–6 months between filter changes. Don't be average.

Finding and Sizing Your Filter

Your filter is located in the return air duct or the furnace itself. Look for a slot or compartment, usually near the blower, with a removable cover or door. Remove the existing filter and check the size printed on its frame — it'll read something like 16x25x1 or 20x25x4. If there's no size printed, measure the length, width, and depth yourself. Write these dimensions down or photograph them. Common sizes for WNC homes are 16x20x1, 16x25x1, 20x20x1, and 20x25x1. Homes with media filter cabinets use thicker 4" or 5" filters.

Choosing the Right Filter Type

Fiberglass filters (MERV 1–4) are cheap but barely filter anything — they protect the equipment, not your lungs. Pleated filters (MERV 8–11) offer the best balance of filtration and airflow for most systems. High-efficiency filters (MERV 13+) capture very fine particles but can restrict airflow in systems not designed for them — check with a technician before upgrading. For allergy sufferers in WNC's pollen-heavy environment, a MERV 11 pleated filter is an excellent choice that won't strain your system.

How Often to Change It

1" filters: every 30–60 days during heavy use (summer and winter), every 90 days in mild seasons. 4" filters: every 6–12 months. Homes with pets, smokers, or dusty conditions should change more frequently. Set a recurring reminder on your phone — it's the easiest way to stay on schedule. During Asheville's heavy pollen season (March–May), check your filter every two weeks.
