Signs Your Ductwork Needs Attention

Your HVAC system relies on ductwork to deliver clean, conditioned air throughout your home, and even small problems can affect comfort and efficiency. Leaks, blockages, and poor design often go unnoticed because ducts are hidden, but they create higher energy bills and uneven temperatures. Over time, neglected ducts can also spread dust, allergens, and other pollutants, reducing indoor air quality. Professional ductwork services help identify these issues early, saving you money on repairs and improving your system’s performance. Knowing the warning signs makes it easier to decide when to call for help.

  • Rooms that are consistently too hot or too cold
  • Rising energy bills without a clear explanation
  • Weak or uneven airflow from vents
  • Dust buildup or worsening allergy symptoms
  • Noisy ducts with rattling, whistling, or banging sounds

Ductwork Services We Provide

Stay Cool Climate Control delivers a full range of ductwork services to keep your HVAC system running efficiently and your home comfortable year-round. From new installations to sealing and repairs, our technicians handle every aspect of duct care with precision and expertise. Here’s how we can help improve your home’s airflow and efficiency:

Ductwork Installation

Our ductwork installation services are designed to ensure your HVAC system operates at peak performance from the start. We carefully design and install air ducts that match your home’s layout and heating and cooling needs. With proper installation, you’ll experience consistent airflow, balanced temperatures, and greater energy efficiency.

Ductwork Repair

When your ducts are damaged, leaking, or restricting airflow, our ductwork repair services provide fast and lasting solutions. We locate and fix issues that cause hot and cold spots, poor airflow, and higher utility bills. By restoring your duct system, we help improve comfort and reduce energy waste.

Ductwork Replacement

Over time, air ducts can become too damaged or inefficient to repair. Our ductwork replacement services provide brand-new, properly sealed ducts that improve airflow and indoor air quality. Replacing old ductwork also helps reduce strain on your HVAC system and prevents future issues.

Duct Sealing

Leaky ducts are one of the leading causes of energy waste in homes. With our duct sealing services, we use proven methods to close gaps and cracks that let conditioned air escape. Proper sealing keeps your system efficient and ensures your home stays consistently comfortable.

Ductwork Inspection

Routine ductwork inspections are the best way to spot problems before they become costly. Our technicians check for leaks, blockages, and damage that reduce airflow and efficiency. With regular inspections, you can extend the life of your HVAC system and avoid surprise repairs.

Ductless Mini Split Systems as an Alternative

Not every home needs traditional ductwork to stay comfortable. For spaces where ducts are impractical, costly to replace, or simply not desired, ductless mini split systems offer an efficient alternative. These systems use individual air handlers placed in different rooms, giving you zoned comfort and precise control without the need for ducts. Mini splits are energy-efficient, easy to install, and perfect for additions, older homes, or spaces where extending ductwork isn’t possible. Stay Cool Climate Control provides installation and service for mini splits, giving you another reliable option in addition to our full range of ductwork services.

Always a great service from these guys. Jacob was out and went through my furnace and cleaned everything up. Very professional and easy to talk to. I’ve had them servicing my hvac for about 6 years now and they have always been able to make things work or work better.

On Jan 16, 2026 I called Stay Cool Climate Control to get a quote on replacing our old HVAC because the furnace was showing signs of imminent failure. I called the office in the morning, and Jeremy was able to come that afternoon. Jeremy looked at the old system and offered us multiple replacement choices. A few days later, after checking with 2 other companies, we concluded that Stay Cool was the best choice for us in terms of cost, efficiency, and equipment quality. We are not disappointed. Installation was scheduled for the following Tuesday. Brandon, Dalton, and Trey arrived on time early that morning, and after seeing the old system began removing it. Even though the outside temperature was in the teens and there was snow on the ground they worked tirelessly all day. By late that afternoon we had a new, highly efficient HVAC system up and running. Our thanks also go to Carter, who has answered many questions and was able to make the quick schedule possible.

HIGHLY Recommend. Our furnace quit right as a winter storm rolled in, and they sent someone out within an hour! Dalton figured out our issue and got our unit to work for just a bit longer until our replacement could be scheduled. Jake and Skylar handled our replacement. The office will send names and pictures of who is coming to your home, which made me feel very safe. Every person we encountered on the phone or in person was professional, friendly, and knew what they were doing. Pricing was fair and transparent, and they helped us get financing. Never felt rushed or pressured. A+ communication.

On time arrival to service my furnace for the winter. Travis was very courteous. He carefully reviewed his findings and answered all of my questions. As a realtor and homeowner, I strongly suggest that your HVAC system be checked, serviced and cleaned twice yearly. Use a professional like Stay Cool Climate Control.

Called 3 companies early in the morning. Stay Cool was able for me to take pics of the area while other companies wanted to come out 3+ days later to look while we had no hot water. Stay Cool was able to come out the same day which was a huge plus for us since we had not had hot water for 2 days already. Their price was also $350 and $700 cheaper than 2 other companies I have had in the past. Travis and Carter showed up on time and walked me through the tearing out and install of the new heater. They were courteous of their wet shoes with slips if they had to go to their truck outside when tearing out the old water heater. Carter, with our older heavy door headed to the garage it doesn't take much to close it. Please be easier in the future. There was an issue with the old water heater being taken up the steps with a dolly that scrapped all the way up the steps in pic 2. I called the main office, they apologized, and they sent Travis back out the next day to repaint. Ill still keep them in mind for future projects. thank you.
