"It went great! Kevin and his crew went above and beyond my expectations. From the initial call, to the complete walkthrough free estimate, to the cleaning, Kevin kept us informed throughout the entire process. I asked for a thorough inspection and cleaning, and that is exactly what we got. They thoroughly cleaned and sanitized our complete HVAC system, including all supply lines, registers, and returns. They even removed and thoroughly cleaned the grills. They opened up the trunk lines and cleaned and sanitized them then sanitized with Foster’s 40:80 antimicrobial product. They sent me videos of their work as they were working throughout the house, and I was shocked to see mold growing in the attic unit. They cleaned and treated it, so hopefully our allergy problems will go away. Because they are mold specialists, I asked about a problem we were having with a leaking window. Kevin and his guys caulked the window and treated the interior wall and didn’t even charge me for the extra work. They were not the cheapest quote, but it was so much better than the last time we had vent cleaning, so the extra cost was so worth it! I highly recommend them and look forward to referring them to others and using them in the future."

"I was first impressed when the owner, Mr Rankin , answered the phone within 2 rings. After explaining what i was looking for , Mr Rankin explained in detail what his company could do as far as duct cleaning of my HVAC system. He was forthright and knowledgeable and answered all my questions regarding his company's reputation and experience. Immediately after our conversation he emailed me a very detailed quite and his company insurance documentation. My appointment was made., and he texted me the names of the technicians. They arrived on time, equipped with booties to wear thru out the house. The work performed took about 4 hours from start to finish. Mr Rankin's techs were extremely polite and very respectful . They also took their tome cleaning up after themselves. We have noticed an immediate improvement, so much so i was considering replacing HVAC unit before i met Mr Rankin. Now the unit is working as it should and my entire hone is very comfotable. I am so happy with the results and if you are considering getting your HVAC ductwork cleaned and sealed , I would highly recommend this company. Good to see great customer service. Thankyou to Mr Rankin and his team of professional technicians"

Heating and Air Conditioning FAQs, answered by experts

If there’s a freon leak in your home’s AC unit, it will cause the system to work overtime to cool the house. That issue will result in higher energy bills and it will take much longer for cool air to disperse throughout the home. If your system has a freon leak during the summer, it can make hot days miserable. That’s why it’s important to hire an HVAC professional to resolve a freon leak as quickly as possible.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

Yes, high-efficiency models reduce environmental impact with lower energy use.

Common signs of insufficient return air include uneven temperatures, with some parts of your home feeling hotter or colder than others, and noticeable differences in air pressure between rooms. You might also observe that more air is blowing in rooms closer to the AC unit. Leaky air ducts can also be a related issue or clue.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.
