DIY HVAC Guy is a blog for homeowners who would rather understand their heating and cooling equipment than pay for a service call every time something beeps.
Most of what goes wrong with a home HVAC system is simple: a clogged filter, a blocked drain, a weak capacitor, a wrong thermostat setting. Those are fixable with basic tools and a little patience. Some things aren't, like refrigerant leaks, gas valves and cracked heat exchangers, and this blog will always tell you where that line is.
How the guides work
Every how-to starts with a job card that shows the difficulty, how long it takes and the tools you'll need, so you know what you're signing up for before you open a panel.
- Easy: no electrical panels, no special tools.
- Moderate: you'll work near low-voltage wiring or a de-energized electrical panel, and you should own a multimeter.
- Advanced: specialized tools, and the manufacturer's manual and local rules take priority.
