Services: Inspections
Home Inspections

The purpose of our home inspection is to provide you with the information you need to assist you in purchasing your home, selling your home, or simply making your home the best it can be. Most homes have conditions that require attention, and it's important to understand how serious those issues are before making any decisions! The inspection report we provide will guide you through what ought to be addressed immediately and which items should be considered in the future. We will provide unbiased answers to your questions and explain potential solutions so that you can make an informed decision about the future of your home.

Inspections are performed with a systematic approach, breaking down the house as a whole into systems and components. Every inspection is accompanied by a report full of photos that will be emailed to you. Our goal is to make the inspection process as easy and understandable as possible for you! During a typical home inspection we will physically inspect and evaluate important elements of the home, such as:


  •  Grounds

  •  Structure

  •  Exterior surfaces

  •  Roof

  •  Windows & Doors

  •  Attic

  •  Interior Rooms

  •  Kitchens

  •  Bathrooms

  •  Basement

  •  Crawlspace

  •  Plumbing

  •  Electrical

  • Heating Systems

  • Cooling Systems

We encourage clients to attend the end of the inspection so we may walk the house with you and discuss what was found and what to expect in the report. Reports are generated and delivered to your email.

At Premium Efficiency we are proud to follow the Home Inspector Standards of Behavior and Standards of Practice Administrative Rules as set forth by the Construction Contractors Board.

Energy Audit Services

You are likely paying more than you need to operate your home. Up to 60 percent of energy used to heat and cool homes can be lost due to leaky ducts, inefficient equipment, poor insulation and air leaks. These inefficiencies may also be causing dangerous situations and compromising the indoor air quality of your home. Premium Efficiency's certified inspectors will help you reach your goals of comfort and efficiency. We offer single measure diagnostic testing of house and duct tightness and whole house Home Performance Energy Audits.

Home Energy Audits may include:

  • Blower Door test to determine building shell tightness and locate leaks

  • Duct leakage and airflow testing to find duct leaks and sizing issues

  • Pressure imbalance testing that can back-draft combustion appliances

  • Combustion appliance safety and efficiency testing

  • Attic and crawl space inspections for moisture and insulation issues

  • Infrared imaging to find hidden insulation, moisture and air leakage problems

  • Comprehensive unbiased report with recommended improvements


If you are selling your home the best way to gain the trust of potential buyers and back up your listing price is to have a Pre Listing Home Inspection performed. By having an unbiased pre inspection done before the home is listed you learn about what items are in need of maintenance, any potential safety issues, or other large repairs that my derail the sale of the home. A Seller's Inspection will uncover the same issues that would be found by a Buyer's Inspection and allows you, the seller, to remain in control of the situation. Once the inspection is completed you can sit down and prioritize the repairs and ensure a smooth sale once the home is listed. The goal is to identify items that a potential buyer would want repaired and make those repairs before the home is listed. When a home is listed as "pre inspected", the inspection helps defend the asking price of the home.

Benefits of having a Seller's Inspection:

  • Reduced stress. The inspection informs the seller what needs to be done to make the home more sellable. You will know what you're getting into and have the time to make appropriate decisions.


  • Higher asking price. By knowing the current condition of a home a potential buyer will not be as likely to present lower offers. You have the proof to back up your price.

  • Make repairs. Issues that are found during the inspection can be addressed and repaired at your convenience and with competitive contractor pricing. A home that is problem free is a great marketing tool. Alternatively, you can provide quotes for recommended repairs to potential buyers.

  • Speed up sales process. Any issues that are discovered can be addresses in advance. Uncovering hidden problems in the middle of the negotiation process can slow things down and even derail a great offer.


  • Good faith. A seller who provides a pre-inspection on their home is operating in good faith and is going above and beyond. This helps to give a buyer peace of mind.


Home Performance
Energy Audits

Home Performance Energy Audits use a comprehensive whole-house approach that looks at all areas of energy use in your home, not just one specific area. Instead of focusing on a single problem such as a drafty room or a leaky window, the house-as-a-system approach looks at how the different components affect each other and how to make upgrades in a safe and cost effective way. A Home Performance Energy Audit includes all the diagnostic and inspections listed above and a Home Energy Score report.

Single Measure
Diagnostic Testing

Leaky ducts can be responsible for up to 20% of the cost to heat and cool your home. Most duct systems have leakage at connections and fittings, while other homes have completely disconnected ducts. Duct tape that once sealed the ducts dries out over time, and loses its seal. These leaks can dramatically reduce the performance of even the most energy efficient equipment. If your HVAC ducts are located outside the conditioned space (attics, crawl spaces), you should have your duct system tested for tightness. A duct leakage test will give an exact duct leakage number and can help to locate disconnected or damaged ducting. If duct sealing is recommended, we can help provide you with a scope of work that you can use to address the duct sealing yourself or to help to get a quote from an HVAC contractor.


How to Prepare for a Duct Leakage Test

Duct leakage testing take 1 -2 hours to complete. All testing is done from inside the home. Please have all registers accessible to mask off. If registers are not accessible due to furniture, please let our staff know when scheduling. If your home has registers over stair ways, or in vaulted ceilings please let our staff know when scheduling (when a tall ladder is required to reach high register grills). After testing is completed the system is physically inspected for leakage areas, damaged areas, and duct insulation condition. Please have the access to the attic and crawl space (areas where ducts are located) clear of any stored items.


Duct Leakage Testing

House leakage testing takes about an hour to perform and can be done in conjunction with duct leakage testing. A Blower Door is set up in an exterior door. All other exterior doors and windows must be closed, and all interior doors open during testing. The Blower Door depressurizes the home to a set pressure and a reading is taken. Please have wood stove and fireplaces free of ashes and debris (no fires during or prior to testing).

How to Prepare for a Blower Door Test

All homes have air leaks, but to what extent? Uncontrolled air leakage can cost you money, compromise your indoor air quality home, and put the durability of your homes structure at risk. A Blower Door Test will locate these leaks in your home. Finding and sealing air leaks in attics and crawlspaces will generally result in the most energy savings and help your home to perform better. After a blower door test you will have a list of building components that need to be addressed, and the best way to tackle each area.

What to Expect from an Energy Audit


How to Prepare for a System Air Flow and Pressure Test

Zonal Pressurization Testing

Forced air heating systems deliver air to different areas and rooms via the duct system. An ideal system will have equal pressures throughout the different areas/zones. When doors are closed to rooms/zones both positive and negative pressures can result. If air is pushed into a room then air must be allowed to get back out of the room and back to air handler. Rooms without a return air pathway can become positively pressurized. Common return air pathways include dedicated ducted cold air returns in each room/zone, jumper return ducts that jump from the room to the common area, or undercutting the door by 1-2" to allow air to be pulled back under the door when it is closed. Positive pressures reduce the amount of air that can enter the room through the supply air registers, push air out of the room and into building structures which can result in moisture related damage. Common rooms like living and family rooms where fireplaces and woodstoves are located can become negatively pressurized. Negative pressures in zones with fuel burning appliances can create dangerous situations where combustion gases and wood smoke are pulled back down the chimney and into the room. Zonal pressure testing can help to identify areas of positive and negative pressures and help to make the system operate properly and safely.

Zonal pressurization testing is generally done at the same time as Duct Leakage Testing. A pressure hose is run to the outside or between rooms/zones and pressure readings are taken while the system is running. As a general rule pressure differences less than +/- 3.0pa between rooms/zones is the target.

How to Prepare for Our
Scheduled Energy Audit

Air flow and pressure testing takes less than an hour and can be done in conjunction with Duct Leakage testing. The system air flow is measured by removing the furnace filter and using a True Flow testing plate where the filter goes. The system is run for 10-20 minutes to get the air handler in to steady state speed and a reading is taken on how much air (cfm) is being moved by the air handler blower. To test the operating pressure a ¼" hole is drilled in the supply and return air plenums and a static pressure probe is inserted. Pressure readings are taken with the system operating and checked against manufactures specifications. The drill holes are then sealed.

All HVAC equipment is designed to move a specific amount of air at a specific pressure. An undersized duct system can make the most efficient heating and cooling equipment perform poorly. A duct system that is undersized can result in excessive fan energy use, loss of efficiency and shorten the life expectancy of the equipment. A system air flow and pressure test will determine if the HVAC system is operating at peak performance.
