    "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.

    He got our furnace up and running again very quickly (on a Saturday!). Very personable and professional! We will definitely be using Custom Engineering Heating & Cooling again - thank you!

    "My experience with the company was great!"
    Chaz went above and beyond! He fixed my main house furnace and also advised me on my ceiling-mounted furnace in my back building. Thank you for your quick response. I will use you again!

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.

  • 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 is the average life expectancy of equipment?
    Most systems have a lifetime of 10 to 20 years. As your equipment gets older, it's efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show it's age, you have two choices. You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new system designed with newer, more energy-efficient equipment makes sense, especially if your system is 10 or more years old. We can estimate the cost of a new system as well as a payback schedule that will show you how newer technology will pay you back in lower energy usage.
  • My system doesn't work well in a couple of rooms, what should I do?
    This can occur for many reasons; uneven solar heat load through windows, an undersized system, an improperly balanced or clogged system, or a single system serving a two-story home with no zoning control. Each situation is different, usually requiring an onsite analysis with problem-specific recommendations. Please call to arrange for us to see your home.
  • Can carbon monoxide build up in my home?
    Yes. Each year, carbon monoxide kills more than 200 Americans and sends nearly 5,000 more to emergency rooms for treatment, reports the U.S. Consumer Product Safety Commission (CPSC). Where does it come from? When carbon-based fuels such as gas, oil, kerosene, or wood burn, they produce gases. Carbon monoxide enters the air when fuel combustion or burning isn't complete. The CPSC advises that carbon monoxide detectors are the only way to alert yourself to the presence of toxic gas in your home. If you wake in the night with a headache, especially if another family member complains of a headache or is difficult to arouse, get out of the house fast and seek medical help. We recommend carbon monoxide detectors be installed in your home!
