Over 20 years of experience in the home comfort and efficiency field. We find solutions to the issues that your HVAC company can't. Dusty homes, hot and cold spots, high utility bills, drafty fireplaces, rooms above garages, cold floors, dirty carpet edges, and much more can be fixed by us. We provide "comfort and energy solutions".

"A total disaster. An inexperienced, untrained crew created more issues than I had before they began their work. My goal was to increase comfort levels in my senior-living, one-level home built on a slab that is super cold in the winter. I hate as a senior being taken advantage of. I was very naive. I have spent thousands and now am having to throw more good money after bad to try and make my home comfortable to live in. It is so bad; I am ready to sell! And I can’t afford to after all I have spent, without taking a loss on the sale. They dense packed my walls and now I am colder; in the process, they removed the flashing above my windows which now leak. I had to hire a window installer to replace the flashing that their incompetent crew removed. They failed to put back the siding properly, so it was hanging off my house. Once again, I had to hire a handy man to refasten the siding the crew removed while dense packing. And the dense packing was useless as it didn't enter the cavities that already had batt insulation. While spray foaming triangle boxes, boots, and plenum, they sealed off all my dampers resulting in zero air flow. They reluctantly came back and had to dig out the dampers that they had foamed over. In fact, they over-foamed at junction boxes, boots, and plenum so that HVAC techs couldn't even tune my system. There is 2 feet of foam, yet hot air is rushing out of the flexible ducts that weren’t sealed properly. Yet there remain gaps on my boxes, boots, and plenum. Just today, a HVAC tech walked me around the attic, and I could feel the hot air rushing into my attic at the junctions, boxes, boots, and plenums that are all wide open; that I paid to have sealed. I almost threw up; I am heating my attic! And the tech said it looks like a dog was in my attic as the Comfenergy crews failed to put back my blown-in fiberglass insulation they removed when trying to foam, so there is no insulation at the boxes and boots. They were simply careless and failed to rake it back and even out my insulation resulting in further cold spots I didn't have. In short, I now will have to hire another company to blow in more insulation and make sure it is even, so I don't have cold/hot spots. Additionally, they left the lights on in the attic, didn't replace the attic access foam barrier, and failed to seal the major penetrations including light cans/recessed lights and supply vents I paid for. Next came the bathroom exhaust fans; they were installed improperly and didn't vent because the outside flaps remained closed, while inside a cold draft came in my bathroom because the foam sealing, I paid for wasn't done properly. So now both my bathrooms are drafty. They were cold; now they are cold AND drafty. The HVAC tech today remarked he felt badly that I have two or more space heaters in every room, including the bathrooms! I strongly recommend carefully watching the crew if you ever choose to allow them to do any work for you. I trusted them. And I regret that. I was naive. I was cold. Rather I am still cold! I trusted their salesperson. The crew that did mine were either let go or quit. In fact, one of them still calls seeking to do side work. I politely declined. I suggest you do the same and seek a competent company that you can trust, does the work you paid for properly, and doesn't damage your home."

Insulation questions, answered by experts

Also known as sound-dampening blankets, acoustic blankets reduce echo in a room. They come in different thicknesses and materials, and they can be nailed or glued to walls.

A DIY blown-in insulation project in a typical attic should take you no more than a week to complete. Experienced homeowners can blow an entire attic in one or two days.

Air duct insulation lasts between 10 to 15 years. How long air duct insulation lasts will depend on the material it's made of and ongoing maintenance.

To extend the life span of duct insulation, consider inspecting it periodically for signs of deterioration, water damage, or general wear and tear. Even if the insulation is in good shape, some homeowners might consider replacing it with newer, more energy-efficient insulation.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

Most projects take 1-3 days, depending on area size and insulation type.
