Experienced in residential and commercial HVAC installations

A professional HVAC installment means the job is done on time with no surprise problems down the line. McNally’s has been handling professional HVAC installations for over 25 years, handling both large and small projects in business and residential units. We provide services you can trust and count on to last you a lifetime. 

Why McNally’s?

  • When you choose McNally’s Heating & Cooling for your HVAC installation, you’re making the right move. Once hired, we send a professional out to do a complete review of your space to make sure the proper equipment and systems are selected for installment. 
  • With over 25 years of experience under our belts, if there’s an issue with your system, odds are we’ve seen it before. There’s no problem too big or too small for the Mcnally’s team to tackle.
  • Our installation team is professional, experienced, and friendly. We know how uncomfortable it can be to have a stranger in your home fixing appliances, so we strive to make the experience as smooth as possible for everyone. 
  • Our team is respectful of your time. We will never be late on purpose and will work diligently to complete the installation in the desired amount of time. 
  • Once the installation is complete, our team will conduct thorough testing of all system components to ensure it’s working properly. If something isn’t performing efficiently, we will take the time to make sure it’s fixed and done right. 
  • When you choose McNally’s, you are choosing honest and upfront pricing. We will never stick you with hidden fees or extra charges unless you choose to add something. 
  • We want to keep our customers happy and coming back for repairs, so we have money-saving options available when you choose us for your HVAC installation, including:
    • Extended warranties 
    • Service agreements including our Pot of Gold Maintenance Plan
