"We installed a Fujitsu mini-split A/C and heat pump because installing duct work was not an option. The entire process from getting a quote to completing the installation couldn't have been any better. Joe went over the full scope of the project including the ramifications if any additional work was needed. I don't think one could find a better HVAC company than Airco!"

"

I called Kris U. in a panic because an unethical contractor had totally messed up our very expensive HVAC system, and the condensers had been sitting unconnected for 18 months! Called Sila, they had no idea what to do. Called Kris and he sent in Gregg H. to reconnect everything, drain the condensers and recharge them again. He did a great job and it turned out we did not have to buy new condensers -- hooray!

I highly recommend this company, since no one else was willing or had the inclination to tackle this.

"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!"

"We called during a heat wave on a holiday week when our A/C broke, so we knew it would take a while to get an appointment, especially as first-time customers. They were able to immediately schedule us for just under a week out, and let us know up top about how their services and payments, etc. work. We actually called another provider simultaneously to see if they could come earlier, but they just ended up giving us the runaround for days instead of just saying they were too busy. They confirmed a smaller time window the night before, and showed up first thing the next day. Abner was awesome, and it was such a huge relief to have someone so nice and professional, explaining everything like we didn't know anything about HVAC (because we don't). He broke down 6 options for us to move forward ranging from the minimum service fee for the cleaning all the way up to addressing everything he saw that was weighing down on the system. He explained which options we could wait on and which ones were higher priority, etc. It feels so rare to get a home service provider with this kind of professionalism these days. I wish these guys did automotive! I didn't rate them on price because I don't have a good comparison. But we will definitely be using them moving forward based on reliability, customer service, and professionalism."

"Our AC unit failed at the end of last season. Jason from Milltown came to our house to review our needs and made a recommendation to our satisfaction. I reviewed all of the data supplied and being an engineer I was totally satisfied with their recommendation. In addition the price was better than I expected. They came early this morning to install a new AC unit with a heat pump. Scott and Joe were are installers plus three others showed up later to support them. My wife and I are in our mid seventies on a fixed income. When our existing system failed and being confined to our home, we had our backs up against the wall. Milltown Plumbing & Heating respected who we are and bent over backwards to help us to have a comfortable home during this pandemic. We are truly grateful to Milltown Plumbing & Heating for helping us and we highly recommend them for your AC and heating needs. Wes M"

Heating and Air Conditioning questions, answered by experts

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

Most HVAC service calls include diagnostic fees, which could include checking on a specific issue you’re experiencing or running through a routine inspection checklist. If you called for a particular problem, the service call will also include an estimate to fix the issue, including materials and labor. Depending on your HVAC technician and the service you requested, you might also get a general inspection of your system components to ensure everything is working as intended.
