  • How Energy Efficient Upgrades Impact your HVAC System

    Many homeowners and business owners have added energy efficient upgrades to reduce their environmental impact. Double-paned windows and high quality insulation can decrease the amount that owners spend on heating and cooling costs. These efforts are also more environmentally friendly because energy is not lost due to leaks. However, many owners don't take into consideration the impact that these improvement have on the HVAC system of the home or business.

    Energy efficient improvements change the heat load of the house. In fact, the US Department of Energy calculated how much the heat load of a 2000 square foot house in North Carolina would change with energy efficient improvements. The hypothetical house improved the insulation in the ceiling and walls, upgraded to double-paned glass, increased the window overhangs and eliminated duct leakage by moving the ducts into the conditioned space. Before the updates, the house's heat load would have been 46,100 Btu/hr by the Manual J calculation. After the updates, it would have been only 21,300 Btu/hr. The energy efficient upgrades cut the heat load in half!

    Unfortunately, many people don't realize the impact that this heat load reduction has on the HVAC system. In the original home, a 4 - 5 ton HVAC system would have been installed. This large HVAC system would have been appropriately sized for the home. However, HVACs are sized based on the heat load. Therefore, after improvements, the proper HVAC sizing would be 2 tons. If the HVAC system is not upgraded with the rest of the house, it will not be properly sized for maximum efficiency.

    The Department of Energy evaluated how much energy savings would result if the HVAC system was upgraded with the rest of the house. With a new 2 ton HVAC system, the homeowners would save 63 percent on heating energy and 53 percent on cooling energy. If the homeowners did the rest of the upgrades but did not upgrade the HVAC system, they would save 54 percent on heating and 47 percent on cooling. It does save energy to do the other upgrades, but homeowners that match the HVAC system to the current heat load gain an extra 10 percent increase in energy efficiency.

    Long lasting HVAC systems are often not included in home and business energy efficiency upgrades. However, they should be. As the heat load of the home or business changes, the HVAC system should be matched to the needs. A right-sized HVAC system could boost the energy efficiency of the home by 10 percent.

  • A Look at HVAC Maintenance for Each Season

    HVAC Maintenance HVAC Maintenance

    One of the poignant facts in life is that nothing is perfect and that includes your HVAC system. One day, everything may begin to fall apart. Therefore, landlords and homeowners alike have one main responsibility and that is to make sure that the tenants or family members can live inside the building comfortably all throughout the year. What does this mean? It means that your home or apartment will be kept cool during the warm months and whenever you need to have air conditioning unit turned on.

    The Truth

    One more regrettable truth about this is that HVAC maintenance and repair needs to have specialized expertise and skills as well as necessary equipment that many homeowners and landlords do not have. For that reason, you are going to need the services of a HVAC repair contractor. The trick about saving money is to schedule an appointment with a HVAC contractor as soon as possible. You cannot procrastinate, but you must know when to make that phone call.

    Do Not Procrastinate

    If you wait too long, or until the AC system is broken, then you may have to wait for weeks or days to get the contractor to come to your home. Remember, these specialists are always busy serving other clients. Below are some suggestions on when you should call the technician so your system can run smoothly all year round. Let’s look at the different seasons.

    The Summer Time

    During the summer, you will definitely need your AC. It is important to get preventative maintenance done during the spring so that you don’t encounter any problems during the summertime. If your air conditioning unit is running, but it is not doing so efficiently, you may want to have the air filters changed and get rid of dust in and around your AC unit. Otherwise, you should solicit the services of a HVAC technician to see what the problem is.

    During the Fall

    As summer ends, the temperature will begin to drop. This is the ideal time to contact an HVAC contractor to inspect your heating and furnace system. The goal is to try to apply preventative measures prior to waiting until issues arise. Furnaces are like any equipment. They need frequent tune up. This is the perfect time, too, to ensure that you have enough filters for your furnace and that they are changed as needed.

    Winter Weather

    There are not many things that are more risky and uncomfortable than to be inside a home with no heat during the winter. While you may have had preventative maintenance done on your heating system, something can still go wrong. Make sure you have the phone number of a reputable HVAC technician that you can call on a moment’s notice.

    The Springtime

    A reasonable time to contact an HVAC contractor is in the middle of spring. At this time, the contractor will look at your HVAC system to see what kind of preventative measures need to be performed. The HVAC contractor may conduct a check and balance on your refrigerant levels, replace filters and clean your system.

    Conclusion

    Lucky for homeowners, most of the HVAC problems can be fixed. However, these problems will usually need specialized skill. Always include your HVAC contractor when heating and cooling system issues arise, no matter the season.

  • What are the Different HVAC Systems to Consider?

    HVAC Systems HVAC Systems

    There are different HVAC systems that homeowners and business owners need to consider when choosing the system that is appropriate for their particular needs. Two such systems are the cooling only split system, cooling only packing system, heat pump, chilled water system, window air conditioners and packaged terminal heat pump.

    Split System

    What is the cooling only split system? It is a blend of outdoor condensation and indoor air handling. The unit for handling indoor air consists of a cooling coil and air supply fan as well as the expansion apparatus. The unit for condensation contains a condenser coil and compressor. These make up the split system, usually found in small commercial offices and residential homes. If you are looking for a high energy efficiency rating for your air conditioning systems, then this split system is recommended. System manufacturers have been required to increase the EER rating to offer varying degrees to accommodate various seasons. If the building requires heating, then a different method is used, but it is generally in the form of gas or electric.

    Packaged System

    The cooling only packaged system is a sole unit with a combination of the same elements in the split system. The unit has to be installed on the exterior of the building since it is packaged. The indoor air has to be ducted away from the building and enter through the utilized air distribution system. The SEER rating for the packaged system starts from 10 and goes up to 18. In a situation where heating is necessary, a different method is used, which is generally gas or electric.

    Heat Pump

    HVAC systems that offer only cooling are similar to the heat pump, but with a single exception. Heat pumps have a unique valve found in the refrigeration piping, which allows the cycle to run in the reverse. The cooling only system works by cooling the air indoors and rejecting the outdoor heat. The heat pump works by cooling the air indoors and upon reversing the valve, it can heat the air indoors.

    Window Air Conditioners

    An air conditioner unit installed in a window or customarily in the opening of a wall is usually accommodated by some homeowners and business owners. This option should be the last resort since a window unit only cools a small and confined space.

    Packaged Terminal Heat Pump

    The window air conditioner unit and the packaged terminal heat pump are quite similar in features. They are installed through a wall opening and are self-contained, requiring electrical connection. The downside is the noise that is emitted and the high operating cost.

    Conclusion

    Choose from the list of HVAC systems wisely. You can receive recommendations from an experienced HVAC contractor before you go ahead and purchase one. You will also need help from an HVAC contractor to install your system.

  • HVAC System Design for Commercial Installation

    HVAC Systems HVAC Systems

    Did you know that your heating and ventilation and air conditioning system provides your home with about 30% energy? This is common for small offices and residential homes as well. When you have a well-designed air conditioning system, it does adequately cool a building, but it also reduces the energy consumption. In addition, it also improves the building’s air quality without causing any damages to the environment.

    Industrial and Manufacturing

    In a manufacturing warehouse or industrial building, the HVAC system has various combinations of devices for heating and cooling. Some of these devices include:

    • Electric heat
    • Heat pump
    • Rooftop unit
    • Furnace
    • Chillers
    • Boilers
    • Central AC units

    For the commercial HVAC system installation, there are various system designs to choose from. For this reason, the installation should be done by an HVAC technician with industrial installation experience because some of these designs can be complicated while others are simple.

    Industrial Plant

    In the industrial plant, a basic system would be utilized in a single zone. Modifications are made when necessary to offer coverage to multiple plants or other large areas. For the basic industrial system, the air comes in from the air intake feature, which is usually found on the side or top of the building. Through atmospheric pressure, the forced air goes through a damper. The air is regulated to take in the amount that is required to cool the building. The air that previously went through the HVAC system will subsequently join with the external air.

    The Combination

    This combination is then filtered through the air filter, removing any large particles in it such as bugs, leaves and dust. After this, there is a second filtration process that handles the smaller particles prior to going through the fan. Once the air comes through the fan, it is then cooled or heated by the coils. If there is any condensation, a drain pan does the collection from the coils. The air then goes through the air duct to heat or cool the building, after which it returns through the air registers to be combined with newly created air or it goes out the building.

    Conclusion

    A basic HVAC system offers comfort to a specifically small space while a commercial HVAC system covers a wider space and has elements that consist of:

    • Packaged units
    • Window units
    • Heat pumps

    You will find a commercial system with evaporative coolers, chilled water systems and direct expansion coolers. So, if you own an industrial plant and need to have your HVAC installation done, the complex nature of it will require an experience and specialized HVAC technician. With a bad HVAC installation, you can end up paying higher cost in energy and have terrible air quality.
