  • Q:How does an Air Conditioner work?

    A:Air conditioning systems work by moving heat from inside your premises to the outside. In a central air conditioning system, air is drawn into the ductwork system through the return air system. Installed in the air stream ductwork is an evaporator coil. This coil is connected to the condenser (outdoor unit) by copper tubing (refrigerant lines).The refrigerant is then pumped from the condenser to the evaporator coil. As the refrigerant passes through the inside of the evaporator coil, it collects heat from the warm air (air stream), passes over to the outdoor unit (condenser), and rejected to the atmosphere. Because the refrigerant is cooler than the warm air, the refrigerant absorbs heat from the air in the duct system. The refrigerant is then sent outside to the condenser unit. When the warmed refrigerant is in the condenser unit it is compressed by the compressor; the compression of the refrigerant causes it to boil. As the refrigerant boils it gives off the heat it picked up from inside your home. The refrigerant is then passed through the coil in the condenser unit where it gets cooled again (heat is rejected to the atmosphere) and is ready to go back inside to pick up more heat from your home. As this whole process is going on, the temperature and relative humidity in your premises are both lowered. The relative humidity level drops because cooler air cannot hold as much moisture. As the air cools, it gives up some moisture and it gets collected in the base of the evaporator coil and is then drained away.

  • Q:How much does it cost to install an A/C and Heating system?

    A:Many factors affect the cost of a heating or air conditioning system, including the size of your home, type of windows, if the house well insulated, the type and condition of the ductwork if installed, and accessories you might like to add such as a touch screen thermostat, zoning system, filtration system, and more. Your specific needs must be met in the design stage before an amount can be given. We have a complete range of systems and accessories available to meet all your needs and we will explore these options during the consultation visit. Our goal is to provide homeowners with the best solution to meet their unique situation and install the most comfortable and efficient system that meet their budget.

  • Q:How long does it take to install or replace a system?

    A:The installation process, when done professionally, is comprehensive and the duration varies from one installation to another. Our technician will survey your home and will cover the matter during the consultation visit.

  • Q:Which brand should I choose?

    A:The Air Conditioning Contractors of America (ACCA) states that the design and installation practices are more important than the brand; the importance of the brand is only 30% or less. That being said, based on our past experience we mostly recommend installing American Standard and Lennox for conventional systems, and Fujitsu and Mitsubishi for mini-split applications.

  • Q:What size should I get?

    A:There is no quick and easy rule of thumb to use for sizing an air conditioning & heating system. The best practice is the use of a formula which is based on the ACCA guidelines (Manual J). The formula takes into account the insulation (attic, walls, and floor), shading, square footage, ceiling height, construction materials, windows size & type, doors, purpose of use and occupancy, orientation, and more. To size your system correctly using these methods, please call us and schedule for one of our experts to meet with you. We use ACCA approved software to size the right system for you and your family.

  • Q:What are the benefits of Air Conditioning?

    A:The benefits of Air Conditioning are to provide a comfortable environment at work or at home throughout all seasons, spring, summer, autumn, and winter.

  • Q:How often should I have my equipment serviced?

    A:Heating and Air Conditioning equipment should be serviced minimum twice a year. The best scenario is to have the system checked in autumn and again in the spring. You can save much more by investing in our comprehensive Energy Saving Program (ESP) which includes 2 precision tune-up visits a year, priority service, extended warranties, cash discounts (10% discount on repairs and 5% discount on new systems and accessories) and most importantly peace of mind. It is a good practice to inspect your filter every 1-2 months and when found dirty, replace it.

  • Q:Why should I have my equipment serviced?

    A:Annual servicing includes cleaning the system, checking for any problems or potential problems, and adjusting for peak efficiency. Some of the benefits of a professionally done tune-up include:  

    Increased dependability.  
    Finding potential problems and fix them quickly.  
    Maximizes efficiency and lowers energy costs.  
    Prolongs the life-span of the equipment.  
    Maintains safe and healthy operation.  
    Helps to protect the environment.  
    Drastically reduces the chance of a break-down which usually happens at the most inconvenient time – at night or on weekends when repair rates are higher.

  • Q:What is included in a Precision Tune-Up Service?

    A:Clean or replace filter 

    Measure temperature drop  
    Measure for correct airflow  
    Tighten electrical connections  
    Monitor refrigerant pressure and charge  
    Lubricate all moving parts  
    Clean the condensation drain line  
    Tighten compressor terminals  
    Verify proper connection for breaker and disconnect box  
    Measure volts and amps draw Inspect evaporator coil  
    Check and adjust blower components and test cycle for proper operation  
    Measure temperature rise  
    Test furnace safety control  
    Test starting capabilities Inspect for gas leaks  
    Verify gas valve proper operation  
    Clean the ignition and burner assembly  
    Monitor flue draft Verify reversing valve operation (heat-pump)  
    And much more

  • Q:What are the benefits of installing a new, energy efficient system?

    A:Today’s best air conditioners use 30%, 50%, and even 70% less energy to produce the same amount of cooling as air conditioners made in the mid -1970s. Even if your air conditioner is only 10 years old, you may save up to 60% of your cooling energy costs by replacing it with a properly sized and installed, newer, and more efficient model.

  • Q:How long will my Air Conditioning unit last before it needs to be replaced?

    A:By having a qualified technician perform precision tune-ups and service the system as suggested your unit will beat the industry standard. Some units last as little as 8 years and some will last 25 years or more. It is hard to predict the life-cycle of an Air Conditioning system but it is known that a well maintained system minimizes costly repairs and to ensure longevity.
