Our Boiler Installation Process

Our professional installers handle every aspect of your boiler installation, from assessing your current system to installing the new unit. Once your system is in place, don’t forget to schedule annual boiler maintenance to keep your unit operating at optimal performance for many years to come.

Types of Boilers We Install

We offer a comprehensive range of boilers to cater to diverse heating needs and preferences. Here are the types of boilers we specialize in:

Gas Boilers: These boilers use natural gas as a fuel type, making them a popular choice for their efficiency and lower energy costs. They’re known for their quick heat production and are ideal for larger properties.
Oil Boilers: Oil boilers are an excellent option if you don’t have access to a gas line. These boilers use oil as fuel and can effectively heat your home while providing you with hot water.
Steam Boilers: As the name suggests, these boilers generate steam to heat your property. They’re known for their robust performance and high-temperature output, which makes them suitable for commercial settings or large homes.
Hot Water Boilers: These boilers heat water and circulate it through radiators or under-floor heating systems to warm your space. They’re efficient, quiet, and can provide a consistent level of warmth throughout your property.

No matter what type of boiler you choose, our team of boiler installers ensures a seamless process, optimizing your new system for maximum energy efficiency and comfort.

Benefits of Installing a New Boiler System

Upgrading to a new boiler is one of the smartest ways to boost your home’s comfort, efficiency, and value. Modern systems deliver reliable warmth while consuming less energy, meaning you’ll notice lower utility bills and quieter operation almost immediately.

Lower Heating Costs: High-efficiency systems use less fuel to produce the same level of warmth.
More Consistent Comfort: Even heat distribution eliminates cold spots throughout your home.
Fewer Repairs: Newer units require less maintenance and are built for long-term reliability.
Cleaner, Quieter Operation: Advanced technology reduces noise and emissions.
Increased Home Value: An updated, energy-efficient heating system adds to resale appeal.
Better Temperature Control: Improved thermostatic precision gives you the perfect indoor climate year-round.

Replacing an outdated system can dramatically improve how your home feels and functions, especially during New Haven’s coldest months.

Why You Should Always Hire Professionals

Boilers are complex heating systems that require precise installation to function correctly. An improperly installed boiler can lead to higher heating bills, potential carbon monoxide leaks, and decreased energy efficiency. Hiring a professional installer not only ensures the job is done right but can also save money in the long run by preventing repairs or a boiler replacement.

How Long Does Boiler Installation Take?

A typical boiler installation usually takes one to two days, depending on the complexity of the system and any modifications needed to your existing setup. Our experienced technicians handle every step efficiently, from safely removing your old system to testing your new boiler for optimal performance. Before installation begins, our team conducts a full assessment of your home’s heating needs to ensure the new system is properly sized and integrated. By working carefully yet quickly, Air Specialties minimizes disruption so you can start enjoying consistent, comfortable heat as soon as possible.

Air Specialties Specializes in Boiler Replacement Services

At Air Specialties, we are committed to providing quality boiler services at a competitive cost. We believe that our customers deserve the best, which is why we only install top-quality new boilers that maximize energy efficiency and reduce heating bills. We also offer a free estimate for our boiler installations, allowing you to plan your budget effectively.

Should You Repair or Replace Your Boiler?

Deciding between boiler repair and replacement depends on several factors, including your system’s age, condition, and performance. A professional inspection from Air Specialties can help you determine the most cost-effective path forward. You may need a boiler replacement if:

Your boiler is 15 years or older
It requires frequent or expensive repairs
You notice uneven heat or cold spots
Energy bills keep rising despite regular maintenance
The boiler leaks, makes unusual noises, or smells strange

You may only need a boiler repair if:

The issue is isolated (like a faulty valve, thermostat, or pressure gauge)
Your system is under 10 years old and generally efficient
Maintenance has been consistent and performance is otherwise steady

Air Specialties’ trained technicians provide honest evaluations so you can make an informed choice that fits your comfort needs and budget.

I had my first HVAC checkup and maintenance today with two technicians from Air Spec - Jim and Zack. They carefully explained everything that they would doing and took extra time listen to my questions and concerns. They were professional, courteous and knowledgeable. The office staff kept me apprised of a short delay due to unusual weather conditions today. I have already committed to my next visit from Air Spec as feel that my system is in good hands. >> There have been two additional visits, with the same technicians, since my first review, both 5-star worthy. Skill, efficiency and service continue to be their watch words.

I have been a homeowner in the Milford, CT, area since 1974, and, through the years, have had difficulty finding a reliable and trustworthy furnace and central air service. I am in my fourth year with this company and couldn't be more pleased. I have the full service contract and am very happy with their promptness, professionalism and courtesy. ...Two years have passed since the comments above, and, in 2024, Air Specialties continues to promptly provide extraordinary service whether the job is great or small!! ...Another year has passed, and Air Specialties continues to provide prompt, courteous and reliable service!!! Both AC and furnace are running fine 24/7!!

I purchased a new HVAC unit with heat coil from Air Specialties about 2 years ago. At the time, I reached out to several HVAC companies. Air Specialties was the only company that I felt actually heard what I was looking for and did not try to upsell.Recently I had two service pros - Jim and Zack come out for A/C maintenance. They were both very friendly and knowledgeable. They explained everything they were doing. They were efficient, professional, helpful and personable!I have been using Air Specialties for 8+ years for maintenance, emergency services and new HVAC unit. The entire company has proven to be friendly, knowledgeable, helpful and timely! Excellent customer service!

I would not recommend this company.. for one they were never responsive on the phone and would never call back with emergencies, secondly were out 4 times and still could not fix the problem. Charged us for each visit, replaced parts that were not faulty such as a 300 dollar thermostat that was working fine. The last straw was when they were suppose to order a part that was under warranty and reported they would call when the part was available. Hence one month later and several phone calls to office and they stated each time that they have to talk with the technician and get back to us and also act like they have no idea what we are talking about.. moved onto a better company and the problem was fixed with the new part within aweek. Horrible company and service.. honestly would not even give a 1 star..

Schedule an appointment with Jeremy in the office for Monday April 12, 2025. I had requested a morning appointment with the tech Mike. I was told Mike was not available till the afternoon so I schedule for 3:00 pm. I receive a call at 1:15 the day of the app by Jeremy if could I be home earlier. My response was 2:00, Jeremy let me call you back, my response ok the 1:45. Answer the door and it’s not Mike. Nothing against the tech I called the office again squeaking to Jeremy, he said Mike wasn’t available in the afternoon today. Not only did they, Jeremy change my scheduled appointment, also changed the tech without any notice, yet! Jeremy knew this morning that Mike would not be available. I then asked for a discount for the inconvenience, according to Jeremy the manager Bob said “no discount” because a different tech arrived instead of Mike! That’s nonsense, Jeremy caused the entire app to change yet claiming it is what it is. I asked to speak to the owner, what a surprise the owner, the manager both are not available to speak to me. I know one or both are sitting in the office, it’s a tactic used when someone does not want to get on the phone. After 25 years of using this company “ a huge disappointment on how my app today was handled. The front line in any business is the office staff, Jeremy is not a person to be answering and scheduling appointments. Poor unprofessional business practice with him. Need to do better with a loyal, long time customer!!!

Unfortunately our gas furnace decided to die just after the new year. We decided to contract Air Specialties HVAC to replace the furnace and upgrade our antiquated analog thermostat. This was absolutely the right decision; they promptly responded the very next day and quickly had the new furnace up and running. The technicians were professional, courteous and thorough. I give my highest recommendation for all your HVAC needs. Five Stars ⭐️⭐️⭐️⭐️⭐️

[January 2024 follow up: Called Air Specialities for an annual checkup. Service was friendly and competent, as usual. Learned further details about our boiler and maintaining it properly. Reasonable fees for the checkup and minor replacement part needed. Always a pleasure working with AS!] Gave a great price when we needed a new boiler back in 2020. Installed promptly and professionally, and they came back to ensure all was working well. They have responded both times we have needed some assistance, and they diligently set about finding a solution each time. Always friendly, prompt, personable, and professional.
