A blower door is a powerful fan temporarily mounted in an exterior doorway to measure how much air leaks through the home’s envelope. With controlled pressure, the assessor pinpoints drafts at baseboards, attic hatches, outlets, and window frames. Finding leakage allows targeted sealing that improves comfort and reduces energy waste. The test is safe, quick, and eye-opening, turning vague feelings of draftiness into precise data that supports smart, cost-effective air sealing strategies and better indoor comfort.
Infrared cameras visualize temperature differences across walls, ceilings, and floors, revealing missing insulation, thermal bridges, and even moisture patterns that could lead to mold. During or after pressure testing, images highlight exactly where your home loses heat in winter or gains it in summer. This visual evidence builds confidence in recommendations and helps you prioritize upgrades. It is also surprisingly engaging, making complex building science easy to understand for every member of the household.
Free assessments are not only about saving energy; they also safeguard people. Combustion appliance zone testing verifies that furnaces and water heaters vent properly. Carbon monoxide detectors are checked, and sometimes installed. Exhaust fans are evaluated for airflow to reduce moisture and pollutants. These steps protect indoor air quality and reduce risks while guiding upgrades that ensure comfort never compromises safety. Many programs include referrals for urgent fixes, giving peace of mind alongside meaningful energy improvements.
One family lived with cold floors and a restless heater that never seemed to stop. The assessment revealed a leaky attic hatch, thin insulation over the living room, and gaps at the rim joist. Air sealing and added insulation quieted the system and evened out temperatures. The family noticed fewer dust drafts and a cozier reading nook by the window. They later replaced aging bulbs with LEDs, appreciating the warmer light and the calmer, more comfortable evenings together.
A renter worried about high summer bills and stuffy rooms. The program supplied LED bulbs, a smart thermostat compatible with building rules, and guidance on using shades strategically. Maintenance sealed a few hallway leaks after the assessor documented them. The space became quieter and more stable, with less temperature swing between sunny afternoons and late nights. The renter now checks usage regularly and shares simple tips with neighbors, proving that meaningful improvements are possible even without full remodeling control.
Before the appointment, gather recent energy bills, clear access to the attic, basement, and mechanical equipment, and make a list of rooms that feel too hot, cold, or stuffy. Note condensation, drafts, or recurring allergies. If safe, check filters and label thermostats. Pets can be secured to keep them comfortable during door testing. Preparation makes the visit more efficient and ensures the recommendations speak directly to your lived experience, turning observations into practical, personalized next steps.
During the walkthrough, ask which actions bring the biggest comfort gains, how rebates stack with financing, and what timelines make sense for your home. Request simple explanations of technical terms and why certain upgrades come first. Ask how to verify results after work is done. The more you understand, the easier it is to say yes with confidence. Empowered questions transform your free visit from an inspection into a collaborative plan that fits your budget and goals.
Set calendar reminders to complete quick fixes, submit rebate paperwork, and schedule contractor bids. Share your report with other decision makers in the household and agree on priorities. Track comfort changes and bill trends for a few months to celebrate progress and spot remaining opportunities. If questions pop up, call the program back; they expect follow-ups and are glad to help. Small, steady steps turn a free assessment into sustained comfort, healthier air, and lasting savings.
