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

If you have a number of large icicles on your roof, you may have an issue with insulation. This is particularly true if you’re also dealing with ice dams. A roofing contractor can diagnose potential insultation issues and help you come up with a game plan to solve them.

Interior walls don't require insulation. However, there are a couple of reasons you may consider adding it in some situations. Insulation in interior walls is excellent for sound-dampening between rooms and can help maintain a regulated temperature in insulated rooms by lowering the heat transfer between adjacent areas of the home.

If you're replacing insulation, it's a good idea to remove the old insulation before adding new. This is especially true if the existing insulation has suffered from water damage or been exposed to pests. You also need to remove old insulation if you'll be installing a new and different type of insulation, such as trading roll or batt insulation for spray foam.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.
