- The compressor or fan hums but does not start.
- The unit starts but then shuts off intermittently.
- Visible signs of damage, such as a bulging or leaking capacitor case.
- Capacitance measures outside of the ±5% tolerance range when tested.
Installation Tips
- Disconnect all electrical power to the HVAC unit before servicing.
- Safely discharge the existing capacitor by shorting the terminals with an insulated screwdriver.
- Photograph or note the wire placement on the C, HERM, and FAN terminals before removal.
- Ensure the new capacitor is physically secured with the original mounting strap or bracket.
- Professional installation is recommended for those unfamiliar with HVAC electrical systems.

Top quality filters at a good price.
Style: 20x30x1
These filters are good quality. They are reinforced and hold their shape. They fit perfectly in my filter holder.
The thing I like is that the filters were bundled together and shipped in a sturdy box. Other filters I have ordered showed up in a flimsy box and were damaged.

Great Fit and Noticeable Air Quality Improvement
Style: 12x24x1
I purchased the Filterbuy 12x24x1 MERV 8 air filters and have been very happy with them so far. They fit perfectly in my HVAC system without any gaps or issues during installation.
After replacing my old filters, I noticed the air in my home feels cleaner and there seems to be less dust settling around the house. They do a good job of capturing everyday particles and allergens while still allowing good airflow.
Overall, this is a reliable and cost-effective 4-pack of filters. Solid quality, easy to install, and a noticeable improvement in air freshness. I’ll definitely be ordering again.
