BPI Accredited Contractor with experienced staff offering the best in energy efficiency assessments and upgrades.

"Two years ago they insulated all walls in our home. A year ago we reached out and asked that they look at a wall in a room that was absolutely freezing cold. They completely missed 2 six feet tall cavities. Kirk said he would do us a favor and finish the job. Gee... thanks. A year later, tons of "I'm working on it", still not done. Now he says he's not getting my texts and that I shouldn't call the office, it's a bad idea. RUN. AWAY. Save yourself the time and headache. Go with any other company."

Insulation & Weatherization.

"WARNING! Do not use this company for home insulation! Climate Giant was hired to complete insulation on my home in June 2023. Instead of properly removing my siding, his workers negligently ripped it out of the center, cut off the tabs and left my aluminum siding with hundreds of nail holes, dents, scratches, cracks, and gaps. These damages have allowed water and insects to get underneath my siding, causing further damage. The workman also backed into my garage with their truck, cut 2 of my window sills, damaged my shutters and gutters. Climate Giant has left me with more than $23,000 in damages to the exterior of my home. While having windows replaced yesterday, the siding around was removed. What we found was that Climate Giant drilled holes around my entire addition that was already insulated and blew in cantaloupe sized amounts to make it look like they insulated it themselves. Clearly the jig is up and I’m completely dissatisfied with the poor quality of work this company provides. For a year now, I have been chasing the company owner Jason Dreyer. In my experiences with him, he has only operated in bad faith and has not resolved any of the issues caused by his workmen. A few examples of Jason’s bad faith actions include, sending a strange man to my house to lie about who he is representing to gain access to my property and information. He had his lawyer send me an intimidating letter claiming that I denied him access to the property to assess damages, as well as denied him the ability to make repairs. This is funny, because two weeks earlier, he was walked around the entirety of my home to assess damages with a member of the CleaResult team. I had not had any contact with Climate Giant since they poorly completed the job on my home and were paid in full by the NYSERDA program. The program had to drag him back out to my house to attempt to work towards a resolution. Jason had his “siding expert” come to look at the damages. Jason had his siding guy write that the damages were due to contraction and expansion from hot and cold temperatures, instead of damages that were clearly created by force and their poor workmanship. When his siding guy provided me with an estimate, it was lacking a price as well as amounts of materials. He had suggested I take his $5,000 settlement offer and go on a nice vacation or what have you, instead of detrimental repairs to my home. As of recent he called me a con artist and scammy for wanting him to make my home whole again. This is defamation and an attack on my character, after I’ve given him nothing but kindness and grace. This company does not take accountability for their poor workmanship. They would rather let a disabled persons home deteriorate than resolve the issues. The only guarantee you will get is the tail light kind. Dissatisfied and Disgusted Customer, Haley Sims"

Energy Efficiency Auditing questions, answered by experts

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

If you install LED bulbs, they will use much less energy than incandescent bulbs. LED light strips also use less power. Battery-operated puck lights use no electricity at all, but you will need to replace the batteries as needed. They are beneficial if your power goes out, too, as they will remain on as a light source. 

Costs depend on pipe length, accessibility, and whether additional services are required.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.
