    • Most systems have a lifetime of 10 to 20 years. As your equipment gets older, its efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show its age, you have two choices. You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new system designed with newer, more energy-efficient equipment makes sense, especially if your system is 10 or more years old. We can estimate the cost of a new system as well as a payback schedule that will show you how newer technology will pay you back in lower energy usage.

       

    • Unfortunately, no. Replacing only the outdoor unit will actually decrease the efficiency of the unit. In fact, you can lose up to 15% of the unit’s efficiency! Even worse, your system may fail sooner than normal and manufacturers’ warranties may be voided. You should always replace the indoor cooling coil with the outdoor unit.

      The good news is, thanks to tax credits that are part of the Inflation Reduction Act, homeowners may be able save up to $3,200 on new home comfort products that meet energy efficiency requirements. The Hauser Air team is on hand to help answer questions regarding which systems are eligible. Homeowners can save money while also making their homes more energy efficient.

       

    • While it may seem like bigger should be better, the answer is not necessarily. You don’t want your air conditioner to be too big. An oversized air conditioner will cool your home faster, but it will use more energy and not remove humidity adequately. This is because a unit that is too big for your home will have short run cycles. Since it takes only a short time to cool the air, the unit shuts off before enough air blows across the indoor coil, leaving too much moisture in the air. This can lead to mold and mildew problems. Short run cycles also mean your system starts and stops more often, which uses more energy and causes a lot of wear and tear.

      Air conditioners typically operate more efficiently during long run cycles. The same holds true with heating systems. An oversized furnace uses more fuel and causes greater temperature swings in the home. The Hauser Air team is here to assist you with knowledgeable experience in selecting the write system for your needs.

       

    • A matched system is important for a variety of reasons. One is comfort. When all your components are properly sized to your home, you can control exactly how much heating or cooling you need so you can relax.

      Also, a properly sized matched system enables every component to perform as designed, meaning proper cycle times are maintained, humidity is controlled, and system sound is minimized.

      Another reason matched systems are important is efficiency. Most systems people buy are too large for their homes, which uses more energy than needed for your home. A matched system outlined by a dealer who has completed a load calculation for your home provides just the right amount of heating and cooling you need so you get the most value for your utility dollar.

       

    • At the risk of telling you something you’re tired of hearing, replace the air filter in your furnace on a regular basis. Dirty air filters reduce the amount of air flowing through a system and make the furnace work harder to maintain the temperature. How often you change the filter depends on the type of filter you use, if you have pets, and the size of your equipment. Please give us a call and we can give you proper guidance.

       

    • Proper air filtration is just as important to the health of your heating and cooling system as it is to the health of your family. Without proper filtration, dust and dirt can build up on your system, which impacts operation and efficiency. A high-efficiency filter will remove more dust, dirt, pollen, mold, and other particles from the air. If you suffer from allergies or other respiratory problems, you should strongly consider a high efficiency filter.

      No matter what type of filter you have, it is imperative to change it regularly for optimal system performance. Hauser Air offers Pro Service Plans to help you take the guesswork out of heating and cooling system maintenance. Call us to learn more or schedule a tune-up now.

       

    • Yes. Keeping your system properly maintained will lower energy and repair costs, prevent breakdowns and prolong the life of your equipment. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.

       

    • Without warranty coverage, a breakdown can mean significant expense in parts, labor, or both. However, with one of our service agreements, you avoid that unexpected significant expense. While no warranty can guard against every possible problem, we can explain the broad range of protection our service agreements afford.

       

    • With a high efficiency air cleaner, you can remove up to 99% of the pollen and spores that find their way into the home. There is also a great reduction in household dust, dirt, smoke, and other air pollutants. Your indoor air will become cleaner and fresher while reducing the allergens and dust that circulate throughout the house. With a whole house humidifier, you can relieve the irritating discomfort of dry indoor air. The humidifier reduces itchy skin, scratchy throats, static electricity, and damage to your furnishings and woodwork. Since humid air feels warmer than dry air, you do not have to set the thermostat as high to feel the comfort you want. A lower thermostat setting will reduce the costs of your energy bill. We offer a complete line of indoor air quality products to meet your needs.

       

    • When humid air passes over chilled cooling coils, water condenses and drips through the coils into a collection pan, from which it continuously drains. Problems with these systems may occur when this water collects and becomes stagnant when it becomes blocked, either on the coils or in the drip pan. The pan will grow mold that can infect your home with dangerous mold spores very quickly. Problems also exist when the HVAC ducting contains microscopic mold spores that stay continually present and blow contaminants around the home or office often caused by mold in other parts of your home.

      You can do 3 things to prevent mold growth in your system:

      • Preventative maintenance will ensure that the collection pan under the indoor coil stays clean and clog free.
      • Install ultra violet lights next to the cooling coils to kill any mold or bacteria growing on the coils or collection pan. Click here to view the UV lights we offer.
      • Keep your ductwork clean by using our duct cleaning service and use a high-efficiency filtration system to keep your entire hvac system clean.

       

    • Duct cleaning refers to the process of cleaning of essential heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, fan motor and fan housing, and the air handling unit housing.

      When is duct cleaning necessary? While it is probably never a bad idea to have your HVAC duct cleaned, it is particularly beneficial if you are having HVAC related problems. These might include things like poor airflow which may be caused by debris clogging a duct, if you have a problem with mold in your home, or if you suspect you might have an infestation of some kind.

       

    • SEER, AFUE and HSPF are all measures of energy efficiency. Air conditioners may look similar, but their Seasonal Energy Efficiency Rating (SEER) can vary widely. Higher SEER numbers save more money spent on electricity. A 13 SEER air conditioner, the EPA “current minimum standard”, uses 23% less energy than a 10 SEER unit (EPA standard up until Jan. 2006). Even though 13 SEER is the minimum efficiency available, we currently offer a line of air conditioners that start at 13 SEER and go all the way up to a 21 SEER. Depending on your average usage, higher SEER air conditioners can significantly reduce your electric bill.

      Heat pumps have SEER ratings like air conditioners and Heating Seasonal Performance Factor (HSPF) ratings for measuring heating efficiency. Higher HSPF ratings mean greater energy savings. The HSPF scale range is 7.5 to 13.0.

      Today’s new high-efficiency furnaces can save up to 50% in operating costs over a ten-year-old furnace. Many 1990 and earlier model furnaces have Annual Fuel Utilization Efficiency (AFUE) ratings of 65% or less. The minimum AFUE rated furnace that can be sold in the United States today is 80%.
      Our current product offering starts at 80% AFUE and goes all the way to a very efficient 98% AFUE rating. Depending on your average usage, higher AFUE rated furnaces can significantly reduce your gas bill.

       

    • Cooling

      Upgrade to a high-efficiency air conditioner – Swapping your old, inefficient air conditioning system for a high-efficient one can cut electricity bills by one-third. Consult one of our professional technicians to ensure your system is the right size for your home, and you aren’t over- or under-cooling for your space needs.

      Turn up the temperature – To save electricity during the summer, set the temperature above 25° as every degree below this will add an extra three to five percent to your energy bill.

      Install ceiling fans – Change the direction of airflow on your ceiling fans. In the summer, the blades should operate in a counter-clockwise direction as a way of creating a nice, gentle wind.

      Have an annual maintenance performed – Having an annual maintenance performed on your air conditioner by a licensed technician will help ensure it operates at its peak efficiency and catches any potential breakdowns before they occur.

      Don’t block vents in well-used rooms – Keep your supply and return air vents free of objects like blinds, carpets or furniture so your air conditioner can operate efficiently and there is even cool air distribution.

      Close vents in less-used rooms – By closing the vents, you won’t be spending money cooling rooms that are used less.

      Heating

      Upgrade to a high-efficiency furnace – New high-efficiency furnaces use up to 50% less fuel than an older system. It can save you up to 25 per cent of your home-heating costs in one year, and within a few years, you’ll have recovered the initial cost of replacing/upgrading your furnace. Choosing a model with an energy efficient motor can save 20 to 50 percent of the energy needed to continuously operate a fan motor. Let us show you the advantages of replacing your old furnace today.

      Have an annual maintenance performed – Having an annual maintenance performed on your furnace by a licensed technician will help ensure it operates at its peak efficiency and catches any potential breakdowns before they occur.

      Install a programmable thermostat – A programmable thermostat enables you to control your home’s temperature when you’re away or asleep. For every 1° you lower your thermostat for seven hours per day, you save one percent on your heating bill.
      Don’t block vents in well-used rooms – Keep your supply and return air vents free of objects like blinds, carpets or furniture so your furnace can operate efficiently and there is even heat distribution.

      Close vents in less-used rooms – By closing the vents, you won’t be spending money heating rooms that are used less.
      Install ceiling fans – Change the direction of airflow on your ceiling fans. In the winter, the blades should operate in a clockwise direction helping to push the warm air from the ceiling down into the room.

       

    • The average home spends about $1,900 annually on energy bills. Heating and cooling accounts for as much as half of a home’s energy use. The EPA provides important recommendations for energy-efficient equipment, including proper sizing, quality installation and maintenance, and other home improvement considerations to help you get the most out of the heating and cooling products you purchase, save energy, and save as much as 20% annually on your total energy costs.

      ENERGY STAR qualified products prevent greenhouse gas emissions by meeting strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE).

       

    • Heat pumps are a great solution for your home comfort system because they work to provide both heating and cooling. Heat pumps have SEER ratings like air conditioners and Heating Seasonal Performance Factor (HSPF) ratings for measuring heating efficiency. Higher SEER and HSPF ratings mean greater energy savings.

      Heat pumps are a very efficient alternative to electric heat. A heat pump works the same as an air conditioner in the summer, but it runs in reverse in the winter to heat your home. The system will be matched with a backup heating source, most often electric heat for those extremely cold days of winter.

      Since they are so efficient, heat pumps and heat pump upgrades are eligible for tax credits that are part of the Inflation Reduction Act. Homeowners may be able save up to $3,200 on new home comfort products that meet energy efficiency requirements. The Hauser Air team is on hand to help answer questions regarding which systems are eligible.

       

    • A Hybrid Heat Dual Fuel system, also known as a Hybrid Dual Fuel system, is a type of heating system used in residential and commercial buildings. It combines two different heating sources to provide efficient and cost-effective heating in various weather conditions. A Hybrid Heat system offers the benefits of intelligent control for both gas and electric heating to create an intuitive system that can actually react to changing conditions.

      No matter what the temperature is outside, a Hybrid Heat system will automatically select the fuel source most efficient for your home, which means you’ll stay warm in the winter, cool in the summer and save money all year long.

      To design a Hybrid Heat system for your home, we professionally match one of our heat pump units with a natural gas furnace. Contact us to see how much energy you can save over your existing system.

       

    • A geothermal system, also known as a geothermal heat pump or ground source heat pump (GSHP), is a highly efficient and eco-friendly heating, cooling, and water heating system that utilizes the stable temperature of the earth to exchange heat with a building’s interior. It uses the earth’s natural heat to provide a comfortable indoor environment while significantly reducing energy consumption and greenhouse gas emissions compared to traditional heating and cooling systems. The Earth absorbs almost 50% of all solar energy and remains at a constant temperature of 50°F to 70°F depending on geographical location. A geothermal unit utilizes this constant temperature for heating and cooling your home.

      You can realize up to 60% energy savings vs. traditional systems. There is no flame, no flue, no odors and no loud outdoor equipment. Heating, air conditioning and hot water can all be obtained from a single compact unit.

       

    • Normal cooling settings are 75 degrees – 80 degrees. Normal heating settings are 68 degrees – 72 degrees. You should always set your thermostat to the highest possible setting that is comfortable for you in the summer, and the lowest comfortable setting in the winter. Setting your thermostat in this way will maximize your energy savings. On average, every 1 degree of temperature change is equal to about 10% energy savings. For example, changing your thermostat setting from 75 degrees to 76 degrees in the summer could result in about a 10% savings on your cooling costs.

       

    • This can occur for many reasons; uneven solar heat load through windows, an undersized system, improperly balanced or clogged system or a single system serving a two-story home with no zoning control. Each situation is different, usually requiring an onsite analysis with problem specific recommendations. Please call to arrange for us to see your home.

       

    • Air conditioners can be loud due to various factors in their design and operation. One of the primary reasons for the noise is the compressor, which is responsible for circulating the refrigerant and compressing it to facilitate heat exchange. Compressors often produce vibrations and mechanical noise during their operation. Additionally, the air handler or blower fan, which moves air through the system, can generate noise as it pushes the air through ductwork or vents.

      A difference of 6 decibels (such as between 72 dB and 78 dB) is technically a four-fold increase in compressor sound when rating air conditioners or heat pump units. However, it takes a difference of 10 decibels to double the loudness. It is also noted that it takes approximately 3 decibels for the average human ear to discern any difference in loudness at all.

      Great strides have been made in reducing the operating sound level of equipment. We will be happy to show you the difference in sound ratings within our product line.

       

    • Yes. Each year, carbon monoxide kills more than 200 Americans and sends nearly 5,000 more to emergency rooms for treatment, reports the U.S. Consumer Product Safety Commission (CPSC). Where does it come from? When carbon-based fuels such as gas, oil, kerosene or wood burn, they produce gases. When fuel combustion or burning isn’t complete, carbon monoxide enters the air. The CPSC advises that carbon monoxide detectors are the only way to alert yourself to the presence of toxic gas in your home. If you wake in the night with a headache — and especially if another member of the family complains of a headache or is difficult to arouse — get out of the house fast and seek medical help. We recommend carbon monoxide detectors be installed in your home!

       

    • Propane (LP) gas: You have this type if your gas comes from a tank located outside close to your house. Propane is stored as a liquid under pressure in tanks and cylinders. In most residential applications, propane is used as a vapor. When liquid propane changes into a gas vapor, it expands in volume. This means that even a small leak of liquid propane can result in a much larger quantity of propane vapor, which can be especially dangerous in a confined space. A chemical odorant has been added to propane to give it a distinct smell. Learn to identify this odor. Propane gas is heavier than air, so it will sink to the floor and spread. To check for the presence of propane, carefully smell all over a room, especially in low spots.

      If you smell propane (LP) gas:

      • Exit your home immediately.
      • Propane gas can ignite easily. Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
      • From a safe area, contact your propane supplier and call 911.
      • If you are able, shut the propane gas supply off at the tank.
      • Stay away from your home until you’ve been told that it is safe to return.

      Natural gas: You have this type if you have a gas meter and pay a natural gas supplier or utility. A chemical odorant has been added to natural gas to give it a distinct smell. Learn to identify this odor. If you smell gas faintly, check all areas of your house for strong odor. If the smell is only faint throughout all areas of your home, call your heating contractor to get it fixed within 24 hours. Keep the house well ventilated by opening windows.

      If you smell a strong, persistent odor:

      • Exit your home immediately.
      • Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
      • From a safe area, contact your gas company or call 911.
      • If you are able, turn the gas off at the meter.
      • Stay away from your home until you’ve been told that it is safe to return.
