from Guaranteed Comfort The Home Performance Experts “Your Comfort is Our Business” Your Comfort is Our Business 􀂉 Comfort - Your Family’s Comfort Depends on the Proper Operation of your Heating and Cooling System. 􀂉 $$$ - The cost to operate and maintain your heating and cooling system over its lifetime is many times larger than the purchase price of the system. 􀂉 Air Quality - Your heating and cooling system can play a vital role in maintaining good indoor air quality. Your Heating and Cooling System Is a Key Part of the Family Home Your Comfort is Our Business 􀂉 Even Temperatures Throughout the House. No hot or cold rooms! 􀂉 Controlled Humidity Levels. No damp feeling when the air conditioner is running! 􀂉 Reasonable utility bills. No more big surprises during hot or cold weather! 􀂉 Good Indoor Air Quality. Your heating and cooling system should contribute to better air quality with proper filtration and sealed duct systems. Some houses may need added fresh outdoor air. What Should You Expect from your Heating and Cooling System? Your Comfort is Our Business 􀂉 According to the U.S. Department of Energy, typical duct systems lose 25% to 40% of the energy put out by the central furnace, heat pump of air conditioner. 􀂉 Studies conducted by utility companies and energy experts throughout the country have verified the two main duct system problems: • Large air leaks in the duct system. • Insufficient airflow due to restrictions in the ductwork. Is There a Thief in Your Ductwork? Your Comfort is Our Business 􀂉 The efficiency label on a new heating or cooling system tells you only half the story. 􀂉 Heating and Cooling systems will only operate at the label efficiency if they are: • Installed correctly. • Connected to a well designed and sealed duct system. • Properly sized for the house. 􀂉 Most heating and cooling systems have 1 or more problems that reduce the true efficiency. What Is the True Efficiency of the Equipment Installed In Your Home? Your Comfort is Our Business 􀂉 The Duct System has Large Air Leaks. 􀂉 The Duct System is Restricting Airflow. 􀂉 The Wrong Sized Heating and Cooling Equipment was Installed. 􀂉 The Heating or Cooling Equipment was Installed Incorrectly. 􀂉 The House has Large Hidden Air Leaks which Create Hot or Cold Rooms. The 5 Most Common Problems Keeping Your Heating and Cooling System From Delivering Comfort Your Comfort is Our Business Comfort Delivery Problem #1 The Duct System has Large Air Leaks Your Comfort is Our Business Duct Leakage Problems 􀂉 Duct leaks prevent your heating or cooling system from doing its job properly. Heated or cooled air leaks out of holes or gaps in the supply ductwork before it ever reaches your house. 􀂉 Leaks in the ductwork also pull outside air (hot in summer, cold in winter) into the ducts, forcing your equipment to run longer to keep you comfortable. AirHandler Supply Duct Wall Cavity Return Air from House Air from attic is pulled through wall cavity into duct system. Your Comfort is Our Business Duct Leakage Problems 􀂉 Duct leaks can draw humid outside air into the house, overwhelming the ability of your cooling system to dehumidify. This can cause your house to feel damp even when the air conditioner is running. 􀂉 Duct leaks can also pull pollutants and irritants such as mold, insulation fibers, car exhaust, pollen and dust directly into your house. Your Comfort is Our Business Duct Leakage Problems 􀂉 Specialized equipment can be used to quickly test for air leaks in the duct system, and estimate the annual efficiency loss from duct leakage. Your Comfort is Our Business Guaranteed Comfort Solutions For Duct Systems that have Large Air Leaks 􀂉 Test for duct air leakage using a Duct Blaster system. The Duct Blaster pressure tests your duct system much the same way a plumber pressure tests your water pipes for leaks. 􀂉 Permanently seal holes or gaps in ductwork with specially designed sealants (no duct tape). Your Comfort is Our Business Guaranteed Comfort Solutions For Duct Systems that have Large Air Leaks 􀂉 Repairs often involve reconnecting ductwork that has become disconnected, or sealing building cavities being used as part of your duct system. 􀂉 Sometimes the best solution is to install new airtight ductwork. 􀂉 Always verify work quality by re-testing for air leakage before leaving. Your Comfort is Our Business Comfort Delivery Problem #2 The Duct System is Restricting Airflow Your Comfort is Our Business Restricted Airflow Problems 􀂉 The proper amount of airflow through your heating and cooling system is critical to its ability to keep your home comfortable. 􀂉 Studies across the country have documented restricted airflow problems in new and existing houses. In one recent study, over two-thirds of the houses checked had low airflow. 􀂉 The main causes of low airflow include: • Return ductwork is too small. • Too many ductwork bends and turns. • Poorly designed filtration systems. Low Air Flow in ACs and Heat Pumps Low Air Flow Correct Air Flow Your Comfort is Our Business Restricted Airflow Problems 􀂉 Low airflow can lead to: • Much lower comfort levels. • Increased utility bills. • Premature equipment failure. 􀂉 Airflow rates should always be tested and verified by a qualified technician. 􀂉 In addition, checking to see that each room in the house is getting the correct amount of airflow is an important part of every installation. Your Comfort is Our Business Guaranteed Comfort Solutions For Duct Systems Restricting Airflow 􀂉 Measure total system airflow using a calibrated TrueFlow meter (or the Duct Blaster system). 􀂉 Measure system “static pressure” (similar to the system’s blood pressure) and examine the duct system for restrictions. 􀂉 Remove duct restrictions (e.g. increase size of return ductwork) and correct other airflow problems. Your Comfort is Our Business Guaranteed Comfort Solutions For Duct Systems Restricting Airflow 􀂉 Install a new filtration system designed for your house and duct system. 􀂉 Re-test final system airflow, and test for proper airflow balance to each room in the house. Your Comfort is Our Business Comfort Delivery Problem #3 The Wrong Sized Heating and Cooling Equipment was Installed Your Comfort is Our Business Bigger is Usually Not Better 􀂉 Many heating and cooling systems are installed without first determining the proper size unit needed for the house. 􀂉 Some contractors use simple rules of thumb to size replacement equipment, or worse, they always recommend getting something a little bigger – just in case! 􀂉 Equipment sizing should be based on an evaluation of the home’s insulation levels, air leakage rate, windows, solar orientation and humidity control needs. 􀀀􀀀􀀀􀀀􀀀􀀀􀀀􀀀􀀀􀀀􀀀􀀀 Your Comfort is Our Business 􀂉 Oversized air conditioners and heat pumps do not run long enough to remove moisture from the air. Result: Your house feels damp and muggy. 􀂉 A June 1998 Consumer Reports Magazine article cautions about being sold an oversized unit. “While an oversized air conditioner may cool a space more rapidly… oversized machines might not reduce humidity very well.” 􀂉 Oversized units also tend to cycle on and off more frequently, resulting in large temperature swings and more wear on the equipment. Oversized Equipment Creates Problems Your Comfort is Our Business 􀂉 The bottom line: If your system isn’t sized properly, there is a good chance it will not work properly. 􀂉 In cases where an existing system isn’t providing proper comfort, simply installing a bigger system without diagnosing the cause of the problem will often make matters worse. 􀂉 Fixing the cause of the comfort problem (poor insulation, duct leaks, restricted airflow or excessive house air leaks) is almost always a better solution than installing a bigger heating or cooling system. Proper Sizing is the Bottom Line Your Comfort is Our Business Guaranteed Comfort Solutions When Wrong Sized Equipment Is Installed in your House 􀂉 Measure the whole house air leakage rate using a Blower Door. The Blower Door system uses a large fan, temporarily installed in a doorway, to pressure test the whole house for air leaks. The air leakage rate is an important factor in determining the correct equipment size. 􀂉 Carefully survey the house’s insulation levels, windows, solar orientation and humidity control needs. Your Comfort is Our Business Guaranteed Comfort Solutions When Wrong Sized Equipment Is Installed in your House 􀂉 Conduct a thorough Equipment Sizing Calculation based on the survey and Blower Door test results. This allows us to more appropriately match the equipment to your house, not your neighbors.

Air Conditioning and Heat Pump Systems Need the Proper Amount of Refrigerant Your Comfort is Our Business Proper Venting of Exhaust Gases from Oil and Gas Appliances is a Must 􀂉 Improperly installed venting systems for gas and oil furnaces and water heaters can let poisonous exhaust gases into your house. 􀂉 Negative pressures in houses from duct leaks and imbalanced duct system airflows can cause backdrafting and spillage of exhaust gases into your house. 􀂉 Measurement of chimney draft and carbon monoxide production should always be done on oil and gas appliances. Your Comfort is Our Business Guaranteed Comfort Solutions For Heating and Cooling Equipment not Installed Properly 􀂉 Measure and adjust the refrigerant level in air conditioners and heat pumps to ensure peak performance. 􀂉 Test for carbon monoxide and proper operation for all oil and gas appliances. Your Comfort is Our Business Guaranteed Comfort Solutions For Heating and Cooling Equipment not Installed Properly 􀂉 Fix all chimney venting problems. 􀂉 Install only equipment that was designed to work together (e.g. replace both the inside and outside units on air conditioners and heat pumps). 􀂉 Always conduct a final quality control check to be sure the equipment is operating at peak efficiency. Your Comfort is Our Business Comfort Delivery Problem #5 The House has Large Hidden Air Leaks which Create Hot or Cold Rooms Your Comfort is Our Business 􀂉 Even if your heating and cooling system is well designed and installed, parts of your house may still be uncomfortable if there are very large air leaks. 􀂉 Uncontrolled air leakage from hidden leak sites in the house can create serious comfort problems. This air leak from an open porch ceiling cavity will likely create an uncomfortable room, no matter which heating or cooling system is installed. Big House Air Leaks Can Create Big Comfort Problems Your Comfort is Our Business Air Leak Problems 􀂉 The picture below shows a number of common locations for hidden air leakage paths into houses. 􀂉 A diagnostic tool, called a Blower Door, can be used help locate these important air leakage sites and determine if they are a likely cause of comfort problems.
