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."

"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence.

"American Home Contractors and Hugo in particular were great to work with. We had multiple jobs done which required several trips and Hugo kept us informed and worked around several weather delays. He relocated and installed a new attic fan, hooked up the bathroom fan to a new roof vent, insulated a pipe in the attic, installed apron flashing on four windows, painted the flue vent, reconnected some lose siding and replaced three pieces of rotted trim and painted it. The work appears to be top notch and we appreciate the hard work and long hours Hugo put in! I would definitely recommend this company and most certainly Hugo to everyone. We also had American Home Contractors replace our gutters and install gutter guards. They did an excellent job with that as well."

FAQs for insulation service projects in Winchester, VA

Yes, you should remove old insulation if it's damaged, contaminated, or deteriorated. Signs like water damage, rodent droppings, mold, or gaps mean removal is essential to maintain energy efficiency and a safe living environment. If the insulation is intact and functioning well, removal isn't necessary. However, compromised insulation can increase energy costs and pose health risks.

Attic insulation lasts 80 to 100 years; however, its performance starts to decline after 15 years. Insulation loses effectiveness as materials like fiberglass become dirty, wet, or affected by mold and other contaminants. Regular evaluation is critical because reduced insulation performance leads to higher energy loss. A professional inspection confirms when replacement is necessary, ensuring that your home maintains peak energy efficiency and comfort.

Excess attic insulation does not enhance energy efficiency beyond an optimal threshold. When insulation surpasses the necessary level for your region’s climate, additional material does not improve heat retention and may cause moisture buildup. Maintaining the correct balance is essential because over-insulation can lead to unintended issues without lowering energy costs. A professional assessment ensures that the amount of insulation is ideal for performance and efficiency, and helps avoid unnecessary expenses.

R-value is the measure of a material’s ability to resist heat transfer and directly determines insulation performance. A higher R-value means the material retains heat efficiently during winter and minimizes energy loss in warmer months. Selecting insulation with the appropriate R-value for your specific location is essential because environmental conditions and installation areas significantly influence energy efficiency. Over time, external factors like moisture may degrade the R-value, which underscores the importance of periodic evaluation.

Insulation damage occurs in several forms, including mold growth, pest infestations, water intrusion, and electrical harm. Damaged insulation compromises heat retention and significantly increases energy expenses while posing serious health risks. Immediate removal and replacement of compromised insulation are imperative to restore optimal performance and ensure the safety of your home. Regular inspections will identify these issues early, allowing for swift corrective action that maintains efficiency and protects occupants.
