    Customer satisfaction is our number one priority. We pride ourselves on Word of Mouth advertising and do our best to live up to our name by being Steadfast in our duty and service.

    We Got You Covered with Financing

    Steadfast Mechanical works with two separate finance systems, to provide our customers with the financial backing you need to stay cool and comfortable.

    How much room do I need?
    Mini-Split systems are able to be installed in a variety of locations and spaces. Most units need 5′ of lateral clearance outside, using either a wall or floor mount, and interior requires about the same. We recommend to install near the top of the wall for best efficiency.
    What does it cost to run?
    Every home or space is different, but a well insulated location in the appropriate square footage should stay between $60-150/month in utility cost.
    Is this a swamp cooler?
    Negative! Swamp coolers depend on moisture to cool the air, which can create a humid atmosphere. With the Mitsubishi Mini-Split system, you will not have humidity with the unit.
    How long does it take to install?
    Most units can be installed in 2-4 hours, provided electricity and access is uninhibited.
    I had an amazing experience! They were super responsive and they were extremely reasonably priced compared to everyone I shopped. Definitely coming back in the future.

    This mini split they did in my shop is a game changer! These guys had better equipment, better warranty, and hundreds cheaper than the other bids I got. My friends are jealous how cool it is when we train or wrench even on these crazy hot days. Thanks Brandon, you do great work!
