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."

"Avoid them...their own intall tech walked into my house, looked at the work order and -incredulously- declared to me that 'whoever wrote this up...they were probably new. But this isn't going to solve your problem". That ACTUALLY HAPPENED. Drying Company completely botched the job. They failed to finish the work (offered some laughable small credit instead) and then sought civil remedy for an amount I don't owe. Oh, and they kept the deposit. To summarize: THEY BOTCHED A JOB AND THEN SUED THEIR OWN CUSTOMER. I was going to let sleeping dogs lie but now I'm going to use every consumer digital megaphone available. Just look at the photo! They were hired to spray foam my crawl space!! That's what they left...They claim this crawl space has been mitigated for pipes freezing."

Your radiant barrier can last up to 80 years or more with minimal maintenance and care. Factors like the quality of the materials you choose and proper installation affect its actual lifespan. Hiring a radiant barrier professional ensures that it's installed correctly to prevent exposure to moisture and other elements, which will help extend its effectiveness.
Installing a radiant barrier in your home offers several benefits that improve energy efficiency and can lower your electricity bills. Mainly, it reduces cooling costs by reflecting heat away from your home, helping to maintain lower indoor temperatures. In the winter, it can help keep warm air from escaping. This reduces the stress on your HVAC system, potentially extending its lifespan and reducing energy consumption.
Additionally, a radiant barrier can protect roofing materials and structural components from extreme temperatures. Pairing your radiant barrier with other insulation systems will provide even more benefits.
A professional installation of a radiant barrier takes one to two days, while a DIY project, due to its complexity, extends the process into several days. The installation duration depends on the size of the attic and the chosen method. For larger homes, experts complete the work in two to three days. Laying foil over existing insulation is a faster procedure that maintains high performance, ensuring the barrier operates efficiently.
A radiant barrier must be installed over existing insulation rather than directly underneath it, ensuring that an effective air gap is created for optimal heat reflection. An adequate air space on at least one side permits the reflective surface to work at peak efficiency, reflecting heat away from the home and preventing moisture issues. This placement method enhances insulation performance and maintains structural integrity by reducing heat transfer and condensation risks, ultimately preserving the quality of both the barrier and insulation.
