Full Heating and Cooling Services in Haverhill
We work on all kinds of systems and setups, whether your house runs on gas, oil, electric, or a mix of everything. Our team handles installations, upgrades, and repairs, and we’re comfortable talking through the pros and cons of different systems before you commit to anything.
Heat Pump and Mini Split Installations
Mini split systems continue to gain popularity across Haverhill, especially in older homes without ductwork. These are ductless heat pumps that give you both heating and cooling in one unit, often with high efficiency ratings and zone-by-zone control. We’ve installed Mitsubishi and Bryant systems in everything from colonials near Winnekenni Park to downtown condos. For homes already set up with ducts, we also install traditional heat pumps that integrate into the central system.
Boilers, Furnaces, and Hot Water Heating
Boiler work is a major part of what we do in Haverhill. Many of the older homes in neighborhoods like Riverside and Mount Washington rely on hydronic baseboard or radiator heat. Whether you’re looking at a Buderus cast iron boiler or a high-efficiency wall-hung model from Viessmann or Rinnai, we’ll walk you through the pros, lifespan expectations, and installation requirements. For homes with forced-air heat, we also install gas and oil furnaces. We’ll make sure your unit is properly sized, vented, and matched to your existing ductwork.


Air Conditioning Installation and Tune-Ups
We install new AC systems, swap out old ones, and handle maintenance in the spring and summer. We pay close attention to airflow issues, coil condition, and refrigerant levels, since those are often the culprits behind poor performance. Our tune-ups help extend system life and prevent midsummer surprises.
Water Filtration Systems
Many homes in Haverhill deal with hard water or off-putting tastes and odors. We install whole-home filtration and under-sink systems depending on what’s needed. We also help homeowners test water before committing to any new equipment. These systems can protect your plumbing and improve the quality of your daily water use.
HVAC Repair Rooted in Integrity
We’ve all dealt with service calls where someone shows up, throws out a big number, and leaves you more confused than when you started. That’s not how we work. We take the time to diagnose issues properly and talk through every option. Sometimes that’s a repair, sometimes it’s a replacement, and sometimes it’s just a small adjustment.
Fast Heating and Cooling Repairs in Haverhill
From frozen mini splits to leaking boilers, we’ve seen it all. Our team handles all makes and models and carries common replacement parts to cut down on return trips. We see a lot of furnace ignition failures during winter, clogged condensate lines in spring, and refrigerant leaks during heavy summer use. We’ve worked in every type of home across Haverhill, from newer developments in Ward Hill to pre war homes near the river.
Full HVAC and Plumbing Inspections
If you’re not sure what your system needs, we’re happy to come take a look. We’ll test airflow, check gas connections, inspect ductwork and condensate lines, and make sure everything is running safely. We give you a full rundown of what we find, what’s urgent, and what could wait.
New Construction and Renovation Services
We’ve worked on custom homes, additions, and full gut renovations throughout Haverhill and surrounding towns. We coordinate closely with general contractors during rough-in and finish phases, and we keep homeowners in the loop so there are no surprises. That means plumbing vents get framed properly, ductwork fits cleanly, and you get the performance you expect once the walls are closed up.
Honest Help Choosing the Right System
Homeowners often ask us what type of system is best. And the truth is, it depends. We give you our take based on what we’ve seen in the field, not just what the manufacturer spec sheet says.
Mini Splits vs. Heat Pumps
Mini splits are great for homes without ducts, older homes with additions, or when you want to control temps in specific rooms. Central heat pumps work well when you already have ductwork and want a full-system upgrade. Both offer high efficiency, but we’ll help you weigh noise, cost, layout, and energy savings based on your goals.
Ducted vs. Ductless Heating and Cooling
Going ductless can be a smart choice, but it’s not the right fit for every home. In places like Haverhill’s Highlands neighborhood, we see homes that mix the two: central air downstairs, mini splits upstairs. We’ll map out what works best based on your layout and comfort needs.
Comparing Furnace, Boiler, and Hybrid Heating Systems
Boilers offer consistent radiant heat and are common in older Haverhill homes. Furnaces provide faster warm-up but can be less comfortable in drafty houses. Some folks opt for a dual-fuel system with both a heat pump and a furnace. We’ll break down the options, pricing, and energy use to help you find the right fit.
Hot Water Heaters: Tank vs. Tankless
Tank heaters are simpler and cost less upfront, while tankless systems offer endless hot water and lower energy use long term. We’ll look at your household size, piping, venting, and budget before recommending anything.
We Install Reliable American-Made Equipment
We’re picky about the brands we work with because we don’t like callbacks, and neither do our clients. We install equipment from companies with a solid track record, strong warranties, and parts that are easy to get. That includes Viessmann, Buderus, Rinnai, AO Smith, Bradford White, American Standard, Bryant, Mitsubishi, and Trane. If we wouldn’t put it in our own house, we won’t recommend it for yours.
Areas We Serve in and Around Haverhill
In addition to covering every corner of Haverhill, we also work in Bradford, Ward Hill, Riverside, and Rocks Village. We regularly take on jobs just across the border in Newton, Atkinson, and Plaistow, NH as well.
