Heating Repair Checklist: What to Check Before You Call a Pro

Is your home feeling more like an icebox than a cozy retreat? When the heat goes out—especially at night or during a cold snap—stress levels can spike. We get it. At Aldo Heating, Cooling & Air, we know the worry that comes with a chilly home, especially when you need emergency HVAC help fast.

Before you pick up the phone, there are a few things you can check on your own. Sometimes the fix is as simple as flipping a switch or swapping a filter. Let’s walk through a step-by-step checklist for homeowners that could save you time, money, and a whole lot of shivers.

Quick Fixes You Can Try 🔍

Even the best heating systems can hiccup. Like a car that needs a jump, your furnace or heat pump might just need a nudge. Here’s your quick-start checklist:

1. Thermostat Check

• Set the thermostat to “heat” mode.
• Increase the temperature a few degrees above the room temperature.
• Replace the batteries if your thermostat is battery-powered.
• Make sure the display is on and reading correctly.

2. Power & Breaker

• Check if your heating system’s switch is ON (usually near the furnace or air handler).
• Inspect your home’s breaker panel; if the relevant breaker is tripped, reset it once.
• If it trips again, stop and call for professional help.

3. Air Filter

• Dirty filters are like clogged noses—air can’t flow.
• Find your filter, slide it out, and hold it up to the light.
• If you can’t see light through it, it’s time to replace.

4. Vents & Registers

• Walk through your home and make sure all vents are open and unblocked by furniture, curtains, or rugs.
• Closed or blocked vents stop warm air from reaching you.

5. Pilot Light or Ignition

• For older gas furnaces: Is the pilot light burning blue?
• If it’s out, follow your manufacturer’s instructions to relight.
• For newer models, check for flashing error codes on the control board.

6. Smells and Sounds

• Sniff for gas smells (like rotten eggs)—if you sense any, leave your home immediately and call your gas provider.
• Listen for new noises: banging, grinding, or squealing. These are red flags.

When It’s Time to Call a Pro ☎️

You’ve done your part. But sometimes, a heating system needs a trained eye and specialized tools. Here’s when to make the call for HVAC Repair near you:

• Burner won’t ignite, or pilot won’t stay lit
• Breaker keeps tripping after reset
• Unusual smells—especially burning or gas
• Loud, persistent noises (banging, rattling, screeching)
• Furnace or heat pump cycles on and off rapidly
• No air movement even with system on

Safety tip: Always err on the side of caution. According to the U.S. Consumer Product Safety Commission, gas leaks and electrical issues require immediate professional attention.

Preventing Future Issues 🛠️

Like changing oil in your car, regular maintenance keeps your heating system humming. Here’s how to reduce the risk of breakdowns:

• Replace air filters every 1–3 months during heating season
• Schedule professional HVAC Maintenance each fall
• Keep vents and registers clear of obstructions
• Install a carbon monoxide detector near sleeping areas
• Make sure your outdoor unit (if you have a heat pump) is free of leaves and snow

Following NFPA (National Fire Protection Association) and local building code guidelines helps keep your home safe.

The Aldo Arrival: What Pros Do

When you call Aldo Heating, Cooling & Air for emergency HVAC, here’s what happens next:

• A licensed technician arrives—day or night
• Full system diagnosis: from thermostat to furnace, ducts to vents
• Use of specialized tools to check for gas leaks, electrical faults, airflow problems
• Safe, code-compliant repairs with quality replacement parts

Costs & Time Factors

Costs vary by issue, parts, and complexity. The important thing: fast action can prevent further damage and higher costs down the line.

When It’s an Emergency

Some heating problems can’t wait. Call for emergency HVAC service if you notice:

• Strong gas smell or visible smoke
• Total loss of heat during extreme cold (especially for households with infants, elderly, or medical needs)
• Water leaks from your furnace or heat pump
• Furnace won’t turn off or is overheating
