Keep Your Home Comfortable Year-Round

Proper insulation is the foundation of a comfortable, energy-efficient home. In San Diego’s climate, good insulation keeps cool air inside during summer and warm air inside during cooler months—reducing the workload on your HVAC system and lowering your energy bills throughout the year.

Many San Diego homes, especially those built before modern energy codes, have insufficient or deteriorated insulation. ASI’s certified technicians evaluate your home’s current insulation levels and recommend targeted upgrades that deliver the biggest impact on comfort and savings. From attic insulation to wall and crawl space applications, we handle it all with our signature White Glove care.

Warning Signs

Signs Your Home Needs Better Insulation

These common problems often point to inadequate insulation.

Uneven Temperatures

If some rooms are always too hot or too cold while others are comfortable, inconsistent insulation is likely the cause. Proper insulation creates even temperatures throughout your home.

High Energy Bills

If your heating and cooling costs seem unreasonably high, conditioned air may be escaping through poorly insulated walls, attics, or crawl spaces.

Drafts & Air Leaks

Noticeable drafts near walls, windows, or floors often indicate gaps in your home's insulation envelope. Sealing these gaps improves comfort and efficiency.

HVAC Running Constantly

If your heating or cooling system runs non-stop to maintain temperature, it's working overtime to compensate for heat gain or loss through under-insulated areas.

I recently had maintenance done on my AC and furnace by ASI, and I wanted to highlight the great experience I had—especially with the technician, Jesus. From start to finish, Jesus was extremely professional, thorough, and clearly very knowledgeable about his work. He took the time to carefully service and clean both the AC and furnace, making sure everything was running properly and efficiently. What really stood out to me was his attention to detail—he didn’t rush the job and even went the extra mile by cleaning the outside of the unit, which I truly appreciated. On top of that, his customer service was outstanding. He was friendly, respectful, and took the time to explain what he was doing, which gave me a lot of confidence in the work being performed. Overall, I’m very satisfied with the service and the level of care provided. I will definitely be using ASI again in the future and would highly recommend requesting Jesus if you want the job done right.

After 21 years of faithful service our heater finally gave out. ASI came to the house and we went over a few options as to repair or replace. We elected the latter, and the very next morning ASI was on site with the new heater. Within 6 hours, Sebastian Garcia and his helper had the new heater installed. Sebastian spent some time explaining how to use the new thermostat, which is so much easier to use than the previous one. By the time they left the garage was clean and all the old stuff was carted away. A great job by an outstanding company. This morning I checked my old paperwork and found that the new heater and thermostat were only a couple of hundred dollars more than the ones I had purchased 21 years ago. ASI really offers good prices and great equipment. A special thanks to the service manager Joe Gondak for keeping in touch with the crew to insure there were no problems during the installation

FAQ

Insulation Questions Answered

Common signs include uneven temperatures between rooms, high energy bills, drafts, and your HVAC system running constantly. Homes built before the 1980s often have insufficient insulation by today’s standards. We offer free assessments to evaluate your home’s insulation needs.

The most impactful areas are the attic (where most heat gain/loss occurs), exterior walls, crawl spaces, and around ductwork. We’ll evaluate your home and recommend where insulation upgrades will deliver the biggest comfort and savings improvements.

Savings depend on your current insulation levels and home size, but the EPA estimates that homeowners can save an average of 15% on heating and cooling costs by sealing air leaks and adding insulation in attics, floors over crawl spaces, and accessible basement rim joists.

Most residential insulation projects are completed in one day. Larger homes or projects involving multiple areas may take two days. We’ll give you a clear timeline during your assessment.

We work with the insulation type best suited to each area of your home, including blown-in fiberglass and cellulose for attics, batt insulation for walls and crawl spaces, and air sealing to stop leaks. During your free assessment we will recommend the right material and R-value for San Diego’s climate and your specific comfort goals.

Insulation work is straightforward and most homeowners stay home during installation. Our technicians protect your floors and belongings, contain the work area, and clean up thoroughly when finished. Attic and crawl space jobs keep the activity out of your living space, so day-to-day disruption is minimal.

Yes. Proper insulation reduces the heat that enters your home in summer, so your air conditioner does not have to run as long or as hard to keep you comfortable. That means more even temperatures, less wear on the system, and lower energy bills. Many homeowners notice the difference right away.
