"We had a dirt floor crawl space and a concrete floor crawl space in our home. Both spaces were very cold and nasty looking. We wanted a solution that would help us become more energy efficient and at the same time create some additional storage space. We initially met with a Perma Seal consultant who walked us through what could be done. He suggested we start by installing insulation in both spaces-which we did through another vendor-and then Perma Seal would install their vinyl liner into the space. Long story short the liners are great-the spaces are bright, clean and dry and we now have a lot more storage space."

"Excellent. I asked initially for quotes for a 96% efficient system vs an 80% efficient system. Based upon the cost difference, rebates, and energy savings, the 80% efficient system matched our budget and tastes. Replaced furnace, air conditioner, and humidifier with a 10 yr parts and labor guarantee Bryant system. They were on time for the 7 AM appointment and were finished by 1 PM. I asked that they retain my 3rd generation Nest thermostat which they did, and they hooked the new humidifier to it. They tested everything (heat, humidifier, and air conditioner) before they left. Very professional and thorough. Parts: -One Bryant model 310AAVS48135 , 135,000 BTUs, 80% A,F,U.E, Natural gas fired forced air furnace. -One Bryant model 113ANA042, 3.5 ton air conditioner with matching Bryant model CNPVU4221 evaporator coil -And a humidifier."

Energy Efficiency Auditing FAQs, answered by experts

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.
