  • What is HVAC?

    HVAC is short for heating, ventilation and air conditioning. HVAC is most often used to depict the whole heating and cooling system consisting of the duct work, air filters, humidification controls and registers. The goal of HVAC is to provide thermal comfort and acceptable indoor air quality.

  • How do I know if I have an existing warranty on my air conditioner or HVAC system?

    A manufacture date can be found on the label on the outer surface of air conditioning equipment. If the equipment is less than five years old it may have a warranty. Warranty terms and conditions change by manufacturer and the installing company. You can verify the warranty directly by calling the manufacturer or Brockhaus can verify the warranty status of your system. Brockhaus offers preventive maintenance plans for both residential and commercial air conditioning systems regardless of how old your equipment is or manufacturer warranty status.

  • What is a service call fee?

    A service call fee is a bill for the expense associated with the time and travel to diagnose, inspect and provide expert recommendations for a home's heating or air conditioning system by a certified professional technician. To avoid costly emergency calls Brockhaus recommends adding a preventive maintenance package. Discounts on service calls are applied with our maintenance packages.

  • Why is it important to have routine maintenance on your system?

    It is important to have routine maintenance on your residential or commercial system because even the best heating and air conditioning equipment could experience complications and become less efficient over time. Routine maintenance inspections are a good way to prevent problems from going unnoticed for longer periods of time. It is recommended to have maintenance performed on your system at least twice a year.

  • Why is my AC system freezing up?

    There are many possibilities that can cause your system to freeze up. Almost all of them usually need to be corrected by a professional technician. Replacing the air filter regularly and making sure the airflow is not restricted are about the only tasks a homeowner should safely identify or handle on their own. Low refrigerant: In some cases, freezing up is initiated by a leak in the refrigerant lines. Weak solder joints, friction from piping rubbing or vibrating against an object, leaking valves or loose fittings can cause leaks. The length of time your system has been installed and the nature and location of the leak are the determining factors on whether to have the system repaired or replaced. Dirty evaporator coil: Over time, the evaporator coil will become dirty. On these occasions, the results are similar to those of having a dirty filter. Gradually you will lose airflow, slowly enough that you probably would not realize it until it freezes up or is not cooling adequately. Defective blower motor or relay: A blower motor running at an improper speed or not running at all can cause freezing. It can also be sporadic, starting at full speed and slowing down after it heats up. Or a relay could cause it to start one time and not the next. Should you discover that your system is freezing due to a dirty air filter, after replacing or cleaning the filter, you can hasten the thawing process by turning the system off and then turning on only the fan. If you have a heat pump system, you can try turning the system to heating mode until the ice has melted. After the ice has melted, switch the system settings back to normal. If the system refreezes, contact Brockhaus Electrical and Air Conditioning.

  • What is a zoning system?

    Zoning Systems separate your home’s duct work into different comfort areas, allowing for independent temperature control in distinct areas that require specific temperature conditioning. For example, a cathedral-style room with large bay windows may retain too much heat in the summer and feel too cold in the winter. A Zoning System will deliver more conditioned air to this large, sun-drenched area to help compensate for the heat gained or lost through the windows. A different example of areas that might benefit from Zoning might be a nursery, home theater or music studio, where different temperatures may be needed in each room for the comfort and enjoyment of the people occupying these rooms. Contemporary families have different lifestyles and comfort needs. You could have a home office that needs extra conditioning during the day and none at night. Or you only use the upstairs or back bedrooms when guests visit. Whatever your needs, a zoning system can maintain each area of your house at the perfect temperature for you and each family member.

  • When should I install a zoning system?

    If you are modifying your area home air conditioner, furnace or heat pump, it is the right time to also install a new zoning system to address hot and cold spots or special temperature preferences in the home. When your new comfort equipment is coordinated by a zoning system, your family benefits fromcustomized temperature control in each zone. Zoning is also excellent for new homes since the system can be installed during construction. If you are investing in a new home, check with your builder about a zoning system. It could make the difference between just enjoying your new house and being truly comfortable in it.
