High Quality Installation Services
Installing a new HVAC system isn’t just about picking a product, it’s about doing the work right so your home stays comfortable without wasting energy or money. We help you decide what fits your space and budget, then install it with attention to every detail.
Mini Split and Heat Pump Installation
Mini splits and heat pumps are ideal for homes that need year-round comfort with low energy use. Whether you want a system for a single room or your entire home, we can guide you through it. We install trusted brands, set up the right number of indoor units, and make sure every part of the system works smoothly before we leave.
Furnaces, Boilers + Hot Water Heaters
We install gas and oil furnaces, tank water heaters, high-efficiency boilers, and on-demand systems. Whether your current unit is beyond repair or you’re planning a new build, we help you choose something that fits your heating needs and matches your home’s energy profile. We also stay up to date on rebates and efficiency programs in New Hampshire so you don’t miss out.
Water Filtration For the Sink or Whole House
Portsmouth’s water supply is generally safe, but taste, odor, and sediment can still be an issue in some homes. We install water filtration systems that match your specific concerns. Whether you want cleaner drinking water at one faucet or whole-home protection against hard water, we’ll give you a few options and handle the install with care.
Trustworthy HVAC Repair in Portsmouth, NH
When your system fails, you need someone who answers the phone and shows up ready to work. Our repair team helps Portsmouth homeowners stay warm in the winter and cool in the summer without overcharging or dragging out a simple fix.
Emergency Heating and AC Repair
We repair furnaces, boilers, heat pumps, air conditioners, and water heaters. If your heat shuts off during a cold snap or your AC starts blowing warm air, call us. We’ll troubleshoot the issue, walk you through what’s happening, and fix it if it makes sense to do so.
We won’t replace your equipment just to make a sale. If the part is available and the unit still has life left, we’ll make the repair and get things running again.
Fast Inspections and Detailed Quotes
Our goal is to keep things clear and straightforward. We inspect your system thoroughly, look for the root of the problem, and give you honest options. That might mean a low-cost fix, a tune-up, or, if needed, a new unit.
Whenever possible, we offer multiple repair paths so you can choose what works for your budget. If something can be fixed for another season or two, we’ll tell you that. We treat your home like we’d treat our own.
High Quality American Products
The equipment we install reflects the work we stand behind. We use Trane, Buderus, Viessmann, AO Smith, Bradford White, Bryant, Mitsubishi, Rinnai, and American Standard, and we will only install the highest quality products in your home.
We also keep track of changes in the market. Who’s buying who? How are internal components changing? Which products are still made with solid materials. If we recommend something, it’s because we believe in it long term.
Help Choosing the Right Equipment
With so many options out there, picking a new HVAC system or water heater can feel overwhelming. We make it easier by explaining the differences clearly and helping you figure out what works best for your home and your priorities.
Mini Split vs. Heat Pump: What’s the Difference?
Both systems use similar technology to heat and cool your home, but there are differences in how they’re used. Heat pumps usually connect to ducts and act like a traditional central system, while mini splits are ductless and allow for zoned control. We’ll help you understand when it makes sense to use one over the other (or when combining both is a smart move).
Why Ductless Systems Are So Efficient
Ductless mini splits are growing in popularity for good reason. They don’t lose energy through leaky ductwork, and they allow you to adjust temperatures in specific rooms instead of the whole house. That means less waste and lower utility bills, especially during shoulder seasons.
They also tend to be quieter, smaller, and easier to maintain than older central air setups. If you’ve been considering one but aren’t sure if it’s a good fit, we can take a look and explain the pros and cons.
Types of Furnaces and Water Heaters
When it comes to furnaces, you’ll need to decide between single-stage, two-stage, and variable-speed models. Each one offers different performance levels and energy use. We’ll explain what those differences mean for your home and how to weigh the cost against long-term savings.
Water heaters come in a few forms: tank, tankless, and hybrid. Some are better for families with high hot water use, while others save energy by heating water only when needed. We’ll help you match the right system to your lifestyle and budget.
Choosing the Right Boiler for Your Home
If your home relies on a boiler, we can help you choose between gas and oil models, cast iron versus high-efficiency systems, and combi units that provide both heat and hot water. We look at your square footage, insulation, and layout to recommend a unit that gives you consistent performance without wasting energy.
