It’s understandable to keep costs low when renovating your home. There are certain aspects of construction and building repair that can be fully performed in-house without taking much of a risk. It can be tempting to choose an installer who can do the job for a really low price, even if the details are a little skimpy. We get it — money is tight.

Your HVAC system, however, is one part of your building you should leave to a qualified professional with demonstrated expertise in their field who will take the time to thoroughly outfit your building with quality equipment and expert craftsmanship. We’ve seen a lot of well-intentioned homeowners make HVAC installation mistakes that have ended up costing them money and time and put them at risk for injury. Let’s take a look at some of the top HVAC installation errors and how you can avoid HVAC installation mistakes in your home.

The Most Common HVAC Installation Errors:

Here are some of the most typical installation mistakes people make when assembling their HVAC system:

  • Leaving Leaks:

    If gaps in your HVAC ducts haven’t been properly addressed, or if flimsy material is used to seal them off, chances are your system is leaking air. This can decrease efficiency, requiring your furnace or compressor to work harder, which draws more energy, needlessly raises your utility bills and puts a strain on natural resources.

  • Improper Design:

    A poorly laid out HVAC system design can lead to inefficient air flow, causing similar issues to that of leaky ductwork. Additionally, a poorly chosen furnace or compressor — one with an output capacity that is not well matched to your building’s particular needs — can cause a lot of headaches and high repair bills. Have your contractor sit down with you to talk through their system plan for your home, and be sure to ask any questions about things you’re unsure of.

  • Poor Venting:

    Carbon monoxide is a deadly byproduct of your HVAC system. If your vent components are not adequately directing it out of your home, your family members’ lives are at risk. Make sure your building is equipped with functioning carbon monoxide detectors, and pay close attention to any warning signs they may give off. Additionally, be sure to talk with your HVAC contractor to make sure the equipment they are using in your vents is sourced from a reputable manufacturer and fits the correct specifications.

  • Insufficient Drainage:

    In addition to requiring a method to disperse toxic gases, your HVAC system also needs a place to eject excess water. Standing water raises the risk of mold growth, foundational damage and frozen pipes. You’ll want to make sure your contractor has a plan for how to effectively drain fluids from your furnace and air conditioning compressor so as to prevent damage and health issues.

What Our Customers Say About Us

Hendley T. just completed maintenance on my oil-fueled furnace. He was thorough, clearly explained everything to me and was extremely professional. He left the work area better than he found it and made me very comfortable with any additional services I needed. It is clear he likes what he does which makes the entire service experience that much better. Highly recommend him if you can request a specific tech! To add, the various techs I have had from B&C have all been great, but Hendley was truly exceptional.

Jason came and gave us great service. I called a different company who told me they were unable to service my hot water heater. So I called Bruni & Campisi. Jason came, figured it out, did a beautiful job. Really appreciate the work.

I had Max the electrician do a thorough inspection of our electrical panel and all outlets in our house. He gave us a thorough report and answered all my questions, offering solutions to any problems he found. The proposal showed indoor work and outdoor work as well as a discount if all the work was done. Bruni and Campisi offers 5 year 0% interest financing. This review is only for a free electrical inspection, part of their annual membership plan, however we have hired Bruni & Campisi in the past for a new furnace and for plumbing and have been very satisfied with their excellent work.

Yuri, Daniel and Obrian were amazing!!!! They installed a new boiler in my parents home in White Plains and did an excellent job. They were professional and kind when engaging with my parents. They had to stay late to finish the work, it is an older home and they ran into some complications but when they finished the install, they removed the old boiler and cleaned up after them selves Thank you!!!!!

Jason, the technician, could not have been more kind, knowledgable, punctual and made the process seemless! Any technical question I asked, he answered. He didn’t have to call anybody. He just had the confidence that I would be looking for in somebody taking care of my heat. I have the most faith in these people, and I will be recommending them from here on out!
