Frequently Asked Questions and Answers

  • Why is it important to have regular maintenance on my home comfort system?

    You wouldn't own a car and never change the oil, replace tires or brakes would you? Well, in the same way, it is essential to have regular precision tune-ups and safety inspections done on your home comfort system. Maintaining your equipment regularly will provide you with the following benefits:
    • Increased dependability
    • Provide maximum efficiency which lowers energy costs
    • Prolongs the life-span of the equipment
    • Maintains safe and healthy operation
    • Can help to protect the environment
    • Find potential problems and fix them right away which will help drastically reduce the chance of break-downs which usually happens at night or on weekends when repair rates are higher.
    Consider a Delta Preventative Maintenance Plan. Having a Preventative Maintenance Plan offers you:
    • Two system checks annually (1 Heating check / 1 Cooling check) each year contract the contract is in place
    • 15% discount on parts, filters and labor
  • Should any additional work be required, a Delta Heating & Cooling technician will provide a written statement detailing the work required.
  • How do I know if there is carbon monoxide in my home?

    The best method to detect carbon monoxide in your home is with a carbon monoxide detector. A carbon monoxide detector is a device very similar to a smoke alarm. It monitors the air for carbon monoxide and sounds an alarm if a specific level is detected.nnIf your house has an attached garage or gas appliances/furnace, you should have a carbon monoxide detector in your home.
  • What size furnace or heat pump do I need?

    There is only one correctly sized heating unit for your home. A trained heating specialist knows all the standards and will evaluate your home to determine the proper size of the replacement equipment. Things like geographic location; overall square footage, level and type of insulation, windows, doors, unsealed chimneys and holes where pipes and wires come into your home can all be major contributing factors to the size of heating unit you need to heat your home. A unit that is oversized will turn on and off too frequently, called "short cycling." Short cycling causes the unit to lose efficiency, and moisture can accumulate in the heat exchanger which might damage the unit over time. A unit that is undersized will run too often, and on the coldest days of the year may not be able to adequately heat the home. The layout of your home can also be a major contributing factor to the size of heating equipment you need, as well. For example, if you have a split-level home with two distinct areas (bedrooms upstairs, family room and kitchen down stairs) and there are only occupants of one area at any given time (like upstairs bedrooms being occupied at night and remaining empty during the day ), this could mean that you want two smaller systems instead of one large system to cover the higher overall square footage.nnContact us today at (509) 943-1092 or at info@Delta-Heating.com to schedule a free estimate with our estimator today.
  • What are the benefits to installing a humidifier?

    With central heating, people are confined indoors with unnaturally dry air for many months each year. Humidifiers help to keep comfortable levels of moisture in the air. Properly maintained levels of humidity are beneficial for your respiratory system. Whole-house humidifiers work like old-fashioned room humidifiers: They put moisture into the air, making harsh, dry air easier to breathe. And whole-house humidifiers use water mist instead of hot steam, which keeps the entire house at the desired humidity level. No more carrying a humidifier from room to room in the winter.
  • How does an air conditioner work?

    Air Conditioning systems work by moving heat from one place to another. The air inside the house is pulled through a duct system where it goes through three main stations; the evaporator, the compressor and the condenser.nnAir from your house is drawn back through a "return air" duct and moved across an evaporator. The warm air blows across the evaporator. The heat is then transferred into the refrigerant. This small amount of heat causes the refrigerant to boil and change to a gas. Gas holds more heat.nnAfter the refrigerant boils and becomes a gas, it moves down a pipe to the outside part of the air conditioning system. Most homes with central AC have a split system—part of it is outside and part of it is inside the house. When the refrigerant gas arrives at the compressor it is put under pressure and compressed. This makes the heat molecules move even faster and become hotter. Then the hot compressed refrigerant heads over to the condenser.nnThe superheated refrigerant is then pushed into a condensing unit. In the condensing unit, a fan blows fresh air across the refrigerant coils and heat is transferred to the cooler air and disbursed into the atmosphere. As the refrigerant gas releases heat it, cools off and condenses into a liquid again. Then, it moves back inside the house to the evaporator, and starts its tour though your AC system again.
  • What size air conditioner do I need?

    There is not a set size that can just be recommended. There are two major decisions that will guide you in purchasing your air conditioner; one is the energy efficiency of the unit and the other is the size of the unit. The size of the air conditioner you need to buy depends on various factors like, what size home do you have, how many square feet? What type of ceilings do you have - whether standard, cathedral or high? The size of your windows - whether small or large? Which direction your prominent windows face? Which type of doors you have - small or large? Only after you have noted down all these factors, can you decide on the size of the air conditioner.

    Proper size is critical to your comfort and savings on your energy bill. Bigger is not better. Oversized units cost more to operate and short cycle so much that your house may become humid and uncomfortable. Undersized units run all day long and still don't cool the house. Make sure you get the right size.
