    "I don't know what I do without this company!"
    Chaz did an amazing job - straightforward and very helpful. Jason and Trey set up the furnace a week ago, and it runs amazingly! It's nice to stay warm again. They just repaired and replaced my bathroom exhaust fan, too. Thank you again!
    - Cesily W.
    "Custom Engineering took care of us right away!"
    Our initial call was after hours and not an emergency. We received a call first thing the next morning, and they came out within a few hours. Both gentlemen were very professional and knowledgeable, and were able to repair our furnace right then and there.
    - Reid K.
    "They have been an excellent company to work with."
    Always courteous & competent. They installed a new furnace, AC, garage gas heater, and ran a gas line into our laundry room. They stayed on the job until all was completed and we were extremely satisfied.
    - Terrance V.
    "10/10 Service!"
    Had Customer Engineering come out to my restaurant to diagnose my furnace and walk-in freezer. Brandon and Skylar, the techs, were amazing. Extremely friendly and knowledgeable. I will be using them for all my HVAC needs moving forward.
    - Taylor A.
    "This business is the best!"
    We bought our kitchen hood system from them, which they also installed (no small task). They are dependable, efficient, and do great work. Prices are what I would expect for the job. Don't hesitate to hire them.

Common Answers To Your Questions

Curious about heating and cooling? Our Custom Engineering team has you covered. Browse through common questions and find expert advice straight from our pros.

  • Is Freon as a refrigerant being discontinued?
    Yes. As of January 2010, the refrigerant R-22 (what consumers call Freon®) is no longer allowed to be used in manufacturing new equipment. R-22 has been used as the "standard" refrigerant for many years but has been found to be harmful to our planet by our government. All new air conditioners and heat pumps use R-410A, the more "environmentally sound" refrigerant.

    R-22 is still the most commonly used refrigerant in existing air conditioning equipment in residential homes today. However, per the Montreal Protocol, caps have been established to eliminate the production of R-22. In 2004, there was a 35% reduction; in 2010, there was a 65% reduction; in 2015, a 90% reduction; and finally, in 2020 a 99.5% reduction in the production of R-22. This means that during the time of these reductions with high demand, the price of each pound of R-22 refrigerant could potentially skyrocket.

    If you are considering replacing your existing air conditioning equipment, most higher efficiency products have already switched to R-410A, the more "environmentally sound" refrigerant.
  • I am concerned about mold growth, what should I do?
    Molds are part of the natural environment. Outdoors and molds play a part in nature by breaking down dead organic matter, such as fallen leaves and dead trees, but mold growth should be avoided indoors. Molds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air. Mold may begin growing indoors when mold spores land on wet surfaces. There are many mold types, and none will grow without water or moisture. Click here to learn more about mold prevention in your home from the EPA.

    When humid air passes over chilled cooling coils, water condenses and drips through the coils into a collection pan, from which it continuously drains. Problems with these systems may occur when this water collects and becomes stagnant when it becomes blocked, either on the coils or in the drip pan. The pan will quickly grow mold that can infect your home with dangerous mold spores. Problems also exist when the HVAC ducting contains microscopic mold spores that stay continually present and blow contaminants around the home or office, often caused by mold in other parts of your home.

    You can do 3 things to prevent mold growth in your system:
    1. Preventative maintenance will ensure that the collection pan under the indoor coil stays clean and clog-free.
    2. Install ultraviolet lights next to the cooling coils to kill any mold or bacteria growing on the coils or collection pan.
    3. Keep your ductwork clean, and use a high-efficiency filtration system to keep your entire HVAC system clean.
  • How can I reduce my energy costs?
    Cooling
    • Upgrade to a high-efficiency air conditioner - Swapping your old, inefficient air conditioning system for a high-efficient one can cut electricity bills by one-third. Consult one of our professional technicians to ensure your system is the right size for your home and you aren't over or under-cooling for your space needs.
    • Turn up the temperature - To save electricity during the summer, set the temperature above 75° as every degree below this will add an extra three to five percent to your energy bill.
    • Install ceiling fans - Change the direction of airflow on your ceiling fans. In the summer, the blades should operate in a counter-clockwise direction to create a nice, gentle wind.
    • Have annual maintenance performed - Having annual maintenance performed on your air conditioner by a licensed technician will help ensure it operates at its peak efficiency. It catches any potential breakdowns before they occur.
    • Don't block vents in well-used rooms - Keep your supply and return air vents free of objects like blinds, carpets, or furniture so your air conditioner can operate efficiently and there is even cool air distribution.

    Heating
    • Upgrade to a high-efficiency furnace - New high-efficiency furnaces use up to 50% less fuel than an older system. It can save you up to 25 percent of your home-heating costs in one year, and within a few years, you'll have recovered the initial cost of replacing/upgrading your furnace. Choosing a model with an energy-efficient motor can save 20 to 50 percent of the energy needed to operate a fan motor continuously. Let us show you the advantages of replacing your old furnace today.
    • Have annual maintenance performed - Having annual maintenance performed on your furnace by a licensed technician will help ensure it operates at its peak efficiency. It catches any potential breakdowns before they occur.
    • Install a programmable thermostat - A programmable thermostat lets you control your home's temperature when you're away or asleep. For every 1° you lower your thermostat for seven hours per day, you save one percent on your heating bill.
    • Don't block vents in well-used rooms - Keep your supply and return air vents free of objects like blinds, carpets, or furniture so your furnace can operate efficiently and there is even heat distribution.
    • Install ceiling fans - Change the direction of airflow on your ceiling fans. In the winter, the blades should operate in a clockwise direction, helping to push the warm air from the ceiling down into the room.
  • What if I smell gas?
    Propane (LP) gas: You have this type if your gas comes from a tank located outside close to your house. Propane is stored as a liquid under pressure in tanks and cylinders. In most residential applications, propane is used as a vapor. When liquid propane changes into a gas vapor, it expands in volume. This means that even a small leak of liquid propane can result in a much larger quantity of propane vapor, which can be especially dangerous in a confined space. A chemical odorant has been added to propane to give it a distinct smell. Learn to identify this odor. Propane gas is heavier than air, so it will sink to the floor and spread. To check for the presence of propane, carefully smell all over a room, especially in low spots.
    If you smell propane (LP) gas:
    • Exit your home immediately.
    • Propane gas can ignite easily. Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
    • From a safe area, contact your propane supplier and call 911.
    • If you can, shut the propane gas supply off at the tank.
    • Stay away from your home until you've been told that it is safe to return.

    Natural gas: You have this type if you have a gas meter and pay a natural gas supplier or utility. A chemical odorant has been added to natural gas to give it a distinct smell. Learn to identify this odor.
    If you smell natural gas:
    • Exit your home immediately.
    • Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
    • From a safe area, contact your gas company or call 911.
    • If you are able, turn the gas off at the meter.
    • Stay away from your home until you've been told that it is safe to return
