Nashoba Air TeamYour heating and cooling systems play the largest role in your total home comfort … but there is more to consider.  Your water heater, indoor air quality, whole house generator, and duct cleaning and sealing all contribute to your family’s comfort and peace of mind that your home is operating at peak efficiency. 

Heating Systems

Gas or Oil – Nashoba Air & BoilerWorks installs a selection of high quality furnaces and boilers ranging from 80% to 98.1% efficiency.  We offer variable speed and two-stage furnaces that feature the ability to constantly move air throughout the home.  This essentially functions as a whole-house air cleaner and greatly increases your home comfort level.
A popular feature to help save energy and fuel costs is an Integrated Zone System. This enables the homeowner to control the temperature of rooms or zones with a separate thermostat, providing even and continuous comfort throughout the home. 

Ductless Heat Pump – If you have a sunroom, a finished basement or any area that cannot be comforted by a typical heating system – a ductless system is a cost-effective, attractive way to control indoor temperatures. Ductless systems are particularly beneficial as the condenser is installed outside the home, ensuring quiet operation inside, while a wall- or ceiling-hung air handler is installed inside. A remotely wired or hand-held controller provides flexible operation which is programmable for timing, temperature, and more. Ductless mini-splits provide a bonus in that you can use them for air conditioning. For more information about ductless systems, visit us on YouTube.

Hybrid Heating Systems – A hybrid heating system can be compared with a hybrid car that uses both gasoline and electricity.  A hybrid heating system uses a combination of electricity and either oil or LP gas.  It has an outdoor condenser that is called a heat pump and an air handler.  The system uses electricity to warm your home in the winter and cool your home in the summer.  On cool mornings in the fall and early winter, you can use the system for heat until the outdoor temperature warms up.  When winter temps drop to the point that you need the whole house heated, the system will automatically switch to your furnace or boiler.  In the summer, the hybrid system is an air conditioner.  A heat pump can use a duct system or can be ductless using a wall-hung air handler to transfer warm or cool air into your home.  Yes, you get air conditioning and heating all in one system!

Zoning Systems – An Integrated Zone System represents one of the highest technological achievements in heating and air conditioning.  Enabling the homeowner to control the temperature of rooms or zones with a separate thermostat, a zoned system runs quietly and provides even and continuous comfort.  Plus … you will save energy and fuel costs as you can lower temperatures in unoccupied rooms or separately program temperatures as desired.

Radiant Heating – Radiant heating is different than traditional heating systems because it heats the objects in the room, not the air.  The system uses flexible, durable PEX tubes under the flooring, through which hot water is circulated at low temperatures.  Heat is transferred upwards and stays near the floor where it is needed, not wasted at the ceiling.  
Radiant heating is efficient and offers room by room temperature control.  It is clean and quiet and can be installed in just one room or the entire home.  You can use any floor covering over radiant heating and is ideal for new, remodeling or retrofit projects.  Furniture placement is optimized as there are no heating vents to get in the way!

Solar Ready Heating Systems – The Dave Lennox Signature® Collection of air conditioners and heat pumps come Solar Ready, which means they can serve as the platform for “going solar.” You simply add roof modules to these systems now or in the future – and in no time, you’ll be running your system “off the grid.”  The experts at Nashoba Air & BoilerWorks will help you select the best technology for your project.

Cooling Systems

Nashoba Air & BoilerWorks installs a full line of air conditioning systems, ranging in SEER (Seasonal Energy Efficiency Ratio) from 13 to 21. We typically install 16 SEER in the Nashoba Valley Region.

Central Air Conditioning – The most common central cooling system includes an outdoor cabinet containing a condenser coil and compressor, and an indoor evaporator coil, usually installed in conjunction with your furnace or air handler. The compressor pumps refrigerant throughout the system. Your cooling system is usually combined with your central heating system because they share the same ductwork for distributing conditioned air throughout your home.

Ductless Air Conditioning – Are you tired of lugging your old window ac units up and down from the basement?  Do you have a boiler?  A ductless air conditioning may be the perfect solution.  A ductless air conditioner, often referred to as a mini-split or heat pump, is a cost-effective, attractive way to control indoor temperatures. Ductless air conditioning systems are particularly beneficial as the condenser is installed outside the home, ensuring quiet operation inside, while a wall- or ceiling-hung air handler is installed inside. A remotely wired or hand-held controller provides flexible operation which is programable for timing, temperature, and more. Ductless mini-splits provide a bonus in that you can use them as a secondary heat source, especially in the “shoulder seasons.”  In the Fall and Spring when you may experience uncomfortably cool mornings or evenings, you can use your mini-split to provide heat without having to turn on your gas or oil heating system.  For more information about ductless mini-splits, visit us on YouTube.

High-velocity Air Systems – If you need to cool an older home or a home with radiant heat, a high-velocity air system may be the ideal choice for you. The system distributes high-velocity air through flexible, pre-insulated two-inch tubing which slides through wall structures and around obstructions. All you see is a small, round, air outlet about the diameter of a compact disk.  Located on ceilings, walls, or floors, the outlets can be painted or wallpapered.

This ultra-quiet central air conditioning system is run by a blower unit small enough to fit inside an attic, basement, or crawlspace. For winter warming, the system can be heated through a hot water coil or electric coil.

Water Heaters

Water Heaters – There are a variety of types of water heaters to choose from and knowing the best one for your home can often be confusing.  Nashoba Air & BoilerWorks will help you select the water heater that will meet your needs.  We’ll ask questions and explain the differences between units so you can make the right decision.

Direct-Vent or On-Demand Water Heaters – A power-vent gas water heater can achieve up to 96% thermal efficiency, provides continuous hot water, and features advanced electronic control.  With up to $500 rebates for qualifying towns – a power-vent gas water heater can also be a great cost saver! Nashoba Air & BoilerWorks also offers other efficient models, so you can select the unit that makes the most sense for your home and budget.  See Save Money!
Hybrid Water Heaters – Hybrid heat pump water heater is a good choice to replace a standard electric heater. While there is more of an up-front investment, the utility savings, coupled with rebates, will save you money long-term.  See Save Money!

Indirect Water Heaters – An indirect water heater draws energy from a boiler and does not need its own heat source.  These water heaters typically boast three to five times more recovery than conventional gas-fired or electric water heaters.  Rebates may be available in qualifying towns.  See Save Money!

Tankless Water Heaters – While an on-demand tankless water heater can save money, it is not an ideal application in many New England areas. Hard water clogs the internal components and Nashoba Air & BoilerWorks discourages the installation of a tankless water heater if you have well water.

Indoor Air Quality

According to the Environmental Protection Agency, scientific studies indicate that the air inside the home can be more seriously polluted with allergens and irritants than the air outside!  Research also shows that Americans spend almost 90% of their time indoors.  For many, the risks to their health and that of their families may be greater due to exposure to air pollution indoors … especially the elderly and chronically ill, the young, and anyone suffering from cardiovascular or respiratory disease, such as asthma.

Some allergens present indoors include humidity, dust, and irritants from household cleaners, paints, pesticides, adhesives, cosmetics, and even air fresheners!  Nashoba Air & BoilerWorks offers a number of indoor air quality products and accessories to give you cleaner, healthier indoor air.

Plasma Air Purifiers – Also known as bi-polar ionization, this technology produces natural oxidizers that seek out contaminants and odors indoors. While reducing gases and odors, it also kills mold, bacteria, and viruses. It works by using naturally occurring, oppositely charged hydrogen and oxygen ions to create a plasma that is injected into a moving air stream.  This plasma breaks down gases and reduces particulates to harmless compounds and filters them out of indoor air.  A plasma air purifier is an excellent replacement for UV systems that require expensive bulb replacement.  To learn more, visit Global Plasma Solutions or check it out on YouTube.

Air Cleaners – Air cleaners have the best overall performance and provide the greatest relief to those with allergies and asthma. They provide quality airflow, removing pollen, dust, and some bacteria.  An electronic filter is up to 40 times more effective than a standard throw-away filter.  An alternate 5” media filter is up to 15 times more effective than a standard throw-away filter.

Dehumidifiers and Humidifiers

Dehumidifiers – Excess humidity in the home can have a huge impact on your comfort.  A whole-house dehumidifier removes just the right amount of moisture for ultimate comfort.  With a dehumidifier, you can eliminate that clammy feeling and indoor “stickiness” and say goodbye to musty odors.  Working throughout your home, a whole-house dehumidifier solves the problem of portable dehumidifiers that are noisy and need to be emptied.  Plus … areas of the home where there is more moisture build-up, like basements or crawlspaces, are dehumidified, even when the heat or air conditioning isn’t running.

Humidifiers – The right amount of moisture is essential to make your home as comfortable as possible.   The right amount of moisture reduces dry throat and dry skin and static shocks.  It keeps your furniture and your home from drying out and increases energy efficiency.  A home with the right amount of moisture feels warmer than a dry home, even at lower temperature settings. For many families, a whole-house humidifier not only provides the right amount of moisture, it can also help to keep irritating airborne particles from circulating as easily.

Heat Recovery Ventilators (HRV) – A heat recovery ventilator pulls pollutants and excess moisture to the outside of the home.  During cold weather, it efficiently recovers heat from the exhaust stream and when the climate is hot and muggy, an HRV pre-cools and pre-dehumidifies incoming air.

Duct Cleaning & Sealing

Duct Clean and Seal Nashoba AirHidden in your ducts may be the reason your comfort system isn’t working as it should.  Collecting dust, dirt, and pollen over the years, your ductwork contains contaminants that not only affect the air quality of your home, but contribute to a less-than-optimal operation of your heating and cooling systems.

Photographic Inspections – Just because someone says there’s buildup in your duct work, that doesn’t mean it’s there. Our video and still cameras go deep into your system to inspect areas you can’t readily see, providing photographic proof of debris that needs to be removed. You get an inside view of your ducts and system so you can make an informed decision about cleaning.  Ductwork inspections also can reveal degraded fiberglass-lined ducts and improperly sealed duct connections.  Finding problems early can save you money and keep your home environment healthier.

To learn more about the importance of duct cleaning, watch this short, informative video.

At Nashoba Air & BoilerWorks, we say, “Clean it.  Seal it.  Breathe it.”

Clean it.  Duct cleaning can remove up to 99% of air contaminants and can dramatically improve a more comfortable interior environment, save energy and lengthen the life of your system.  At Nashoba Air & BoilerWorks in addition to our system ductwork cleaning, we offer bathroom exhaust duct cleaning; dryer vent cleaning; filter servicing; and HVAC and ductwork deodorizing. 

Seal it.  In the average home, a ducted comfort system leaks 30% to 40% of air flow before it ever hits a register. This energy is lost in the basement, between the indoor and outside walls of your house and even in the attic. Using Aeroseal™  technology, Nashoba Air & BoilerWorks can reduce your leakage rate by as much as 95%. Your energy bills will be lower, fewer contaminants will be sucked into your duct work, your equipment will last longer, and ice dams will be less likely to form in the winter.

Breathe it.  With Nashoba Air & BoilerWorks you’ll have the cleanest and healthiest indoor air possible.  

Plumbing & Electrical

Sometimes a home comfort project requires a Master Plumber or Electrician to handle a part of the job.  Most HVAC companies sub-contract this work … but not Nashoba Air & BoilerWorks.  We know HVAC and we have a Master Plumber and Electrician on staff to handle all code changes and to obtain necessary permits.  Today the codes require that both a plumbing license and gas fitting license is needed when installing new gas piping around a gas furnace.

Whenever plumbing or electric work is required for your home comfort project, you can depend on Nashoba Air & BoilerWorks to do the entire job and that means meeting our own high standards as well as yours.

Keeping your heating and cooling system maintained is key for top working efficiency and for saving fuel costs. There are additional benefits as well … Learn how our Peak Performance Maintenance Program can give you peace of mind and reduce the risk of your system failing just when you need it most!
