Is your house always too hot in summer? Or does it feel drafty in winter, no matter how much you run the furnace? You’re not alone. Most homes lose energy in surprising ways, and that means money slipping through your fingers.

Colibri Air HVAC knows what it’s like to get sticker shock from monthly utility bills. With certified auditors and 24/7 emergency hvac service, we help homeowners like you find—and fix—what’s costing you extra every month.

Why Energy Audits Matter

Imagine your home like a bucket with tiny holes. No matter how much you fill it (with heat or cool air), it leaks. That’s wasted energy. Every unseen gap, poorly sealed vent, or aging insulation means your systems work harder and you pay more.

An energy audit is a detective’s search for those leaks. It’s not just for old houses or drafty farmhouses. Even new homes can have hidden problems.

What Happens During a Home Energy Audit? 🔎

A home energy audit is part science, part sleuthing. Here’s what you can expect when Colibri Air HVAC comes to your door:

  • Blower Door Test: We set up a powerful fan in an exterior doorway to gently pull air out. This reveals where air sneaks in—around windows, doors, or even through light fixtures.
  • Infrared Camera: Like x-ray goggles, this tool spots spots where insulation is thin or missing. Cold or hot spots show up as bright colors on the screen.
  • Duct Inspection: We check for leaks, dust, and blockages. Leaky ducts can waste up to 30% of your heated or cooled air (U.S. Department of Energy).
  • HVAC System Review: Is your furnace, AC, or mini-split system running efficiently? We look for signs of wear, aging components, or incorrect sizing.
  • Insulation Check: Walls, attic, and floors are inspected. Good insulation is like a cozy jacket—too thin, and you’ll feel every draft.

Quick Home Energy Safety Checklist

Before you book a professional audit, here are a few things you can check for yourself:

  • Windows and doors: Can you feel cool air on a windy day, even when they’re closed?
  • Furnace filters: Dirty or clogged filters force your system to work harder.
  • Vents and registers: Are they blocked by furniture or dust?
  • Thermostat: Is it responding accurately, or are you always fiddling with the settings?
  • Visible insulation: In the attic, does it look even and thick, or patchy and thin?

If any of these are a problem, it’s a sign your home could benefit from a deeper look.

DIY Fixes vs. Calling a Pro

Some energy leaks are easy to spot and fix. Weather-stripping a drafty door or swapping out a filter? Go for it.

But not every problem is DIY-friendly. Hidden duct leaks, faulty thermostats, or missing insulation behind walls call for experienced hands. Emergency hvac issues, like sudden furnace breakdowns or AC failures, should always be left to trained technicians—especially if safety codes or electrical work are involved (see National Fire Protection Association guidelines).

What Pros Do When They Arrive

Colibri Air HVAC’s certified auditors follow a thorough checklist:

  1. Initial Walkthrough: We ask questions about your comfort and energy use.
  2. Blower Door Test: Measures how much air escapes your home.
  3. Infrared Scanning: Finds hidden cold or hot spots in walls, ceilings, and floors.
  4. Duct Pressure Testing: Pinpoints leaks inside ductwork.
  5. HVAC Inspection: Checks for proper installation, maintenance needs, and efficiency.
  6. Ventilation Review: Ensures a balance between fresh air and energy savings.
  7. Written Report: You’ll get clear, actionable steps ranked from small DIY fixes to big-impact upgrades.

Prevention & Maintenance Tips

Energy audits aren’t just for fixing problems—they help you prevent new ones.

  • Change filters every 1–3 months.
  • Schedule AC Maintenance near you at least once a year.
  • Keep vents and registers clear of obstructions.
  • Add or replace insulation in attics and crawl spaces.
  • Seal windows with caulk or weather stripping.
  • Upgrade to programmable thermostats for smarter energy use.

According to ENERGY STAR, even simple upgrades like sealing air leaks and adding insulation can save 10–20% on annual energy bills.

How Much Does a Home Energy Audit Cost? And How Long Does It Take?

Costs vary depending on your home’s size and the depth of the audit. A typical audit takes 2–4 hours. Larger homes or those with complicated HVAC systems may take longer.

Most homeowners earn back the cost of an audit through lower bills in just a few months. Some upgrades, like LED lighting or improved insulation, pay for themselves even faster.

Remember, ongoing issues—like a furnace that runs nonstop or an AC that never cools—can cost much more over time if left unchecked.

When Is It an HVAC Emergency?

Some problems can’t wait:

  • Furnace or AC stops working during a heatwave or deep freeze.
  • You smell gas or burning (leave your home and call emergency services).
  • Water leaks from your HVAC system.
  • Electrical issues, tripped breakers, or sparks.

Local and Seasonal Considerations 🌡️

Every region faces unique challenges. In humid climates, audits focus on moisture control and dehumidifiers. In cold areas, attic insulation and radiant heating matter most. Seasonal changes—like pollen in spring or dry air in winter—can also affect indoor air quality and system performance.

Colibri Air HVAC brings experience in all climates, helping you choose upgrades that make sense for your home and weather.


A home energy audit is more than just a checklist—it’s a smart investment in comfort, safety, and savings. Stop letting money slip through the cracks.
