• How often should I change my filter?
    1” Standard Air filter is recommended that you check these at least once a month.

    4” filter should be check and/or changed every 6 months. Once at the beginning of the air conditioning season and once at the beginning of the heating season.

    Electronic Air Cleaner (EAC) is recommended to be cleaned 4 times a year.

    If your filter is getting dirty quickly it’s a sign that there is dirt getting into your system, commonly this is attic air being sucked in and carrying attic dust and dirt. Call your HVAC service company to schedule an appointment.

  • Why does my AC unit stop cooling, the thermostat goes blank and then starts again after a while?
    This indicates it’s an issue with your AC condensate drain line – typically its blocked. Check that your bathroom sinks are draining, if not clear the drain. If the problem continues, call out your HVAC technician.

  • My system is not cooling, and I can see Ice on the copper lines on the unit outside?
    Ice build on the copper lines and not cooling indicates there is a problem with the AC system. The problem will get worse before it gets better. There are several potential issues, you should have a technician determine the root cause to fix the issues.

  • Why is there water coming out a pipe outside my home?
    Go to your water heater and check the tray/ pan underneath – if it has water call a plumber – you have water heater issues. Next, check you AC the pan underneath (emergency drain pan). If the problem continues, call out an HVAC technician.

  • I’m noticing humidity or condensation issues in my home. What should I do?
    The ideal relative humidity in a home should be close to 50 percent. Humidity levels that are above or below that threaten to cause mold or other health issues. There are options, such as a modulating system or humidifier, to help monitor and regulate in-home humidity. If the problem continues or if you would like to get more information, schedule a service call with an HVAC technician.


  • What is the life expectancy of an HVAC system?
    A typical system is around 12 years – we have seen systems that are recommended for replacement after 6 years and we have worked on systems that are 35 years old. The two major factors that impact the life of your HVAC system are the quality of the equipment installation and having quality routine maintenance on the system.

  • What does SEER mean?
    Seasonal Energy Efficiency Ratios are used to indicate how efficiently an air conditioner or heat pump will operate during the cooling season.

  • What does EER mean?
    EER stands for Energy Efficiency Ratio. EER values are commonly used when looking at the energy efficiency of smaller window units. The EER will not give you an accurate representation of your future energy bills, but it can provide a good way to compare two systems.

  • What is the difference between a heat pump and a furnace?
    The main difference between the two is how they create heat. A heat pump uses electricity to move heat from one place to another. A furnace burns fuel to create heat.

  • What is the difference between variable speed versus a single-stage or a two-stage?
    A single-stage is on or off – like a light switch or driving from Lewisville to Denton at zero or 60 MPH, no in-between.

    A two-stage system has two stages it operates at. For example, driving from Denton to Flower Mound at 40 MPH or 60 MPH. Or a light switch that is Off bright and full settings. The operating system will operate most of the time at the single-stage giving efficiency in temperature extremes of a lot of cooling or heating the 2nd stage will kick in for the peak times.

    Variable speed is akin to a dimmer switch 0 to 100%, or driving at whatever speed is appropriate. A variable speed system is the most comfortable system and is always moving from low flow to high speed. The system ramps up and down based on the set point. As air is always moving there is less humidity to feel uncomfortable.

  • How often should I have maintenance on my HVAC?
    We recommend that you have your air conditioning system checked each spring and your heating system checked each fall. You can use the beginning and end of daylight-savings time to help you remember to call for service.


  • I just moved into my home; how do I check for a system warranty?
    The warranty needs to be updated to the current homeowner’s name if your home has a Trane unit.

    For Trane call 1-855-260-2975 and provide the address. New homeowners have 60 days from the time of purchased to have the warranty transferred into their name. Fee’s may apply. It is critical for the 10-year warranty period to be under the correct homeowner’s name. If it is not under the current owner’s name, the warranty defaults back to a 5 year.

    For Lennox – Extended Warranties are not transferable to subsequent homeowners. They only cover the original homeowner. If a second homeowner moves into a home the unit will revert to its limited factory warranty of 5 years. The unit will be warranted by a serial number based on the build date for subsequent owners. If you have any questions, call Lennox at 1-800-953-6669.

    If we can help you in the process call us and we will help get you sorted.

  • What is a connected control thermostat?
    A thermostat which is designed by the manufacturer to work with the equipment to operate in the most efficient way. A Nexia thermostat / Trane will give the capability of accessing your system remotely moving temperature up and down. Seeing run time data & it will send you as well as your Trane dealer any alerts if it detects problems with your system.


  • Do you have proof that your are bonded and insured?

  • What brands do you sell?
    We are a Trane and Lennox dealer.

  • Can you give me an estimate over the phone?
    Because every home is different it is nearly impossible to put an exact price on a new system without having our project manager over to your location to ensure that if/when we install a new unit, everything will be up to city code.

  • What size system do I need?
    Having an AC system that is too large may cool your home too quickly, leaving behind moisture that could lead to mold problems for your home or business. Also, too-large AC systems tend to short-cycle (starting and stopping quickly, repeatedly) which decreases the lifetime of your AC and increases your electricity bills.

    At the other end of the spectrum, having a system that is too small won’t ever keep your home or business cool and will run constantly.

    Because there is no “rule of thumb” for sizing an AC system, we do measurements of the home to determine what size system is needed.
