Comprehensive Home Energy Audits

Assessing your home's current home energy efficiency is critical to figuring out what the current problems are.  Before we work on your home, we will perform a thorough home energy audit to get an idea of what is going on.  Our energy evaluation will give us an idea of what we need to do to fix your home.  After we complete the audit, we will take the time to sit with you and educate you as to what the best plan would be to fix your home, and why.  From there, we can perform any work we think is beneficial to improving the energy efficiency and comfort of your home.

Experienced Window Installation Contractor

Did you know that your windows play a big part in improving your home's energy efficiency?  In fact, many windows do not seal as well as they should and allow air to leak out. At Dr. Energy Saver, A Blackdog Affiliate we can install new windows in your home.  Unlike other contractors in the area, we can replace your existing windows with low-e glass! Low-e glass has a coating that emits almost no radiant energy and blocks most ultraviolet (UV) longwave energy, which we feel as heat. Our low-e glass replacement windows help control the temperature in your home all year long. 

Dehumidification & Indoor Air Quality Solutions

Temperature and humidity can have a huge impact on your comfort. Excess moisture in your home can create musty odors and cause mold and mildew, which can aggravate allergies and asthma symptoms. Most homeowners make the mistake of turning up their air conditioner in an effort to reduce humidity. This does very little to improve comfort and increases energy costs. If you live in Nashua, you know that humidity is especially high in the summertime. Dr. Energy Saver, A Blackdog Affiliate can install a dehumidifier to help reduce moisture, eliminate odors and improve your home's comfort. Less humidity in the air also means that you'll feel cooler at a higher temperature and will be using less energy to keep your home comfortable. We are Nashua's certified installer of SaniDry dehumidifiers. Our dehumidification systems offer high-capacity moisture removal and energy-efficient performance.

Job Stories From Nashua, NH
New in Nashua, NH

Bob was in the process of purchasing a little ranch home in Nashua, NH. He met with the home inspector, and was surprised to get some really great advice. Even though the home passed inspection, the inspector encouraged Bob to get more attic insulation, he worried that the home would hemorrhage heat in the winter and lose cool air in the summer. 


We checked out Bob's home and agreed with that inspector! But we didn't only add insulation to the attic, we also installed a hatch cover and extended his bathroom fan to seal up all the places air can escape. Bob could have easily gone to the local hardware store, bought pink fiberglass insulation, and rolled it out... but that wouldn't have solved his issues. Dr. Energy Saver Northshore thoroughly insulated Bob's home. 



A Cape in Nashua, NH

We met Nashua homeowners Janice and Roger at a home show in Manchester, NH. Roger was worried about ice dams and Janice just wanted a warmer basement and 1st floor. the couple loved their cute Cape Cod style home, but wanted to feel more comfortable in the winter.


Dr. Energy Saver Northshore has a specfic solution for Cape style homes. We air seal the roof and use both foam and cellulose insulation in the attic. This combination proves to be particularly effective for this style of house. After working on the top of the house, we headed down to the basement to spray foam. This combination both reduced ice dams and made the home warmer.

Marie Ave in Nashua
We just bought this home in November and it always feels very cold and drafty. There are 3 floors, the basement which is about 70% finished, the ground level and a upstairs, each level has its own thermostat, the basement is warm and set at 68. The main level or what I call the ground floor is cold and no matter what I set my heat to it don't get over 65 on cold days like today, the upstairs is even colder at 57 on average. I would like a estimate on the cost to find where all the cold air is coming in and or where my heat is escaping. Thank you.
