The Homeowner’s Checklist: When to Call an HVAC Repairman (and When to DIY)
Introduction
Your HVAC system is the heartbeat of your home’s comfort. When it breaks down, you’re left sweating in the summer or freezing in the winter. The question is—should you try to fix it yourself, or do you need a professional? Some HVAC issues can be tackled with basic maintenance, while others require an expert. This guide breaks down when to call an HVAC repairman and when to DIY.
The Essential HVAC Checklist: DIY or Call a Pro?
- Weak Airflow: DIY First, Then Call a Pro
If your AC isn’t blowing air as strongly as it used to, check the air filter first. A clogged filter restricts airflow and makes your system work harder. Swap it out and see if the problem improves.
When to Call an HVAC Repairman: If changing the filter doesn’t help, there could be a bigger issue, like a failing blower motor or a blocked duct. That’s when it’s time to call in the experts for AC Repair Gilbert.
- AC Not Cooling Properly: DIY First, Then Call a Pro
Before you panic, check your thermostat. Make sure it’s set to “cool” and the temperature is lower than the room temperature.
When to Call an HVAC Repairman: If the AC is running but not cooling, it could be a refrigerant issue, a frozen coil, or a compressor failure. This is where professionals like Olive Air and Heating come in.
- Strange Noises: Call a Pro
HVAC systems should not sound like a horror movie. Grinding, squealing, or banging noises mean something is wrong.
DIY Fix: Tighten any loose screws or panels.
When to Call an HVAC Repairman: If the noise persists, it could be a motor failure, a belt issue, or a problem with the fan blades. AC Repair Gilbert specialists can diagnose and fix it fast.
- Unusual Smells: Call a Pro Immediately
Your HVAC system should not smell bad. Musty odors could indicate mold in the ducts, while a burning smell might mean an electrical issue.
When to Call an HVAC Repairman: If you notice a burning or gas-like smell, shut off the unit and call Olive Air and Heating immediately.
- Leaking Water Around Unit: Call a Pro
Your AC unit has a drain line that removes condensation. If you see water pooling around the unit, check for a clogged drain line and clear it with a wet/dry vacuum.
When to Call an HVAC Repairman: If the leak persists, you might have a refrigerant issue or a broken drain pan, which requires professional repair.
- Short Cycling: Call a Pro
If your AC turns on and off rapidly, it could be an electrical issue, a clogged filter, or even a refrigerant problem.
DIY Fix: Change the filter and make sure the thermostat is working.
When to Call an HVAC Repairman: If short cycling continues, your system could be overheating or suffering from compressor failure. A local HVAC Repairman can diagnose the issue quickly.
