"Airco is a great family-owned and operated business, very fair and knowledgeable. They replaced our forced air central heating system (oil) in a day, and were quick to respond and get to work despite how busy things were during the January cold-spell. I would highly recommend for your heating and cooling needs!"

"Deserving more than 5 stars on all. Customer Service which I had not experienced with duct cleaning + business previously ! explaining all their process before beginnng actual cleaning. I asked for several of their business cards to share! I have never done so with any other " cleaning " air quality Service! I had spoken to a local high sales realtor within the same morning to recommend, as I gave her his business cards! I will continue to recommend NEQAS to anyone I know who uses or will be needing such services. Taking pictures inside ducts ,before doing any work, directly in front of you is quite impressive display of honesty.comparing the before and after pictures are easy to recognize same ductwork. Honesty flows as a natural way of doing business. I am very impressed with total interactions from scheduling with Debbie, including her explanations of fees etc. and follow up emails, as we have bad to no cell service at location. Schedule was met entirely as planned. Would never call or recommend any other company. VT is lucky to have them Service`our area."

Small jobs welcome

"My central AC unit has been broken for several years. intermittently working during hot summers. I've had several HVAC companies come to diagnose and all of them told me different things: replace the whole system, new lines, etc. potentially costing tens of thousands of dollars. So I decided to troubleshoot by myself and pinpointed the issue: the filter dryer needed to be replaced. No company wanted to do this small job. I called Emerald HVAC and told them about my issue, they sent in José, who diagnosed the issue to be what I said. He replaced the filter dryer and the AC unit works perfectly now after several years! In short, Emerald HVAC will be my first choice for any HVAC work in the future. They are honest, professional, and reasonably priced. I recommend them without reservation!"

"Due to the pandemic it took a while for the park to come in, but after the park came in they were able to fix it the same day. They were terrific and very helpful. They provided portable AC units during the time when our AC was down. This was very good of the company to do."

Customers say: Super punctual

"Great experience with Milltown. Their sales manager Jason came out twice to meet with me personally and tailor a proposal to my needs. I had some non-HVAC ancillary work needed (ice maker line) and they were happy to incorporate this. On the day of install, Derek and the onsite team were friendly, professional, and responsive to all of my questions. Price was competitive with two other bids I had solicited. I would highly recommend working with Milltown and would work with them personally again without hesitation."

Air Conditioning questions, answered by experts

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

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.

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.
