"He was timely, professional and responsive. He clearly knows the technical aspects of the trade and provided us with a lot of information about the equipment he would be installing and how it would work with our existing ductwork.  We did not care for his sales approach because he tried to sell us on things we did not ask for and did not need.  He tried to sell us on a humidifier for the system which we really don't need because we live right by the ocean where it is quite humid year round, even in the winter. Adding humidity to our house could cause problems with mildew or mold.   He also tried to sell us on replacing our hot water tank for a more efficient model even though ours is only 5 years old.  We got the feeling that he was trying to pack as much sales onto the heat loan program without really thinking about the customer's specific situation, and that put off me and my husband from wanting to work with him.  At the end of his sales presentation he decided on the spot he would give us an unspecified discount.  We did not like this high pressure sales tactic.  We had not received other quotes yet so we declined to decide on the spot.  He emailed us a couple days later offering a 10% discount if we decided by a certain date a couple days later.  We decided to wait beyond that date so we could get more bids.
Joe's quote was $2000 higher than a quote from another installer who has equally good reviews on Angies list.  Both quotes were to install the same equipment, however the second installer included the cost of converting two unused ducts into returns and installing a pass though in a ceiling to help balance our system.  I shared this information with Joe, and he responded by saying he would beat their price by $100.  It goes to show that it pays to shop around. 
As Airco's good reviews on Angies list attest and my interactions with him, I am sure they would do quality work, but my husband and I were totally put off by his sales and pricing approach and did not want to work with the company as a result.

"We've used Atlantic Heating & AC for many years and wouldn't consider any other company. Atlantic is extremely responsive, priced reasonably, and they always do a great job. We've never once had to call them back to resolve any issues associated with their work, and they've done a lot of work over for us over the last 9 years. Recently, our water heater died very suddenly; I came home from my office and water was leaking out of the water heater onto the basement floor. Within minutes, their service manager was guiding me over the phone regarding which valves to turn off etc. and he had me take a few pics to send to him. The very next day, a serviceman was at our house installing a brand new, much better water heater than the house had come with, and we haven't had an issue yet, and this was several months ago. I'm a Realtor and Atlantic has bailed my seller clients out of HVAC issues on a moment's notice, so I will always be grateful for the excellent sales and service that we receive thanks to Atlantic Heating and AC."

"I finally got to build my dream garage to store all my tools and have a cool hangout on Friday nights with the boys n a couple coors. Chris came and did everything from the bathroom and the heating system. I will definitely be calling him back to add a mini split in the future. He was professional, punctual and clean. Very knowledgeable you can tell he cares about his clients."

Install Boiler questions, answered by experts

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.
