"Great company to work with. They're very thorough on what needs to be done to fix a problem and are very professional. So far they've done two repairs to my heating system and were always pleasant and willing to help. Keith and Ron are great guys and I'll be calling them for my HVAC 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."

Heating and Air Conditioning FAQs, answered by experts

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season.
