"I was happy with the job that was done. It provides insulation plus a vapor barrier. He put in a radiant barrier. It looks almost like tinfoil. They crawled around under the house installing it. It insulates better then conventional insulation. My house is warmer when it is cool and cooler when warm."

"I had called Insulation Pros for an estimate with very short notice as well as two other companies. Conrad was the second person to give me a detailed estimate also was more then pleased to come out to my house and write me a real in hand quote. He was on time and very informative on the project. The following Monday the 2 professional men came to my house and did the job that I was promised and within the time that was allotted. Cleaned up and was off to the next shortly after seeing if I was pleased with the job. These guys are awesome. I do recommend Insulation Pros to anyone thinking about getting insulation done.
Thank you and all your staff.

My wife and I did a thorough search in getting the best A/C Contractor in the Sacramento area.  The search included Angie?s List, Better Business Bureau, California State Contractor?s License reviews, personal recommendations from neighbors and friends.  After all our searching we ended up going with Diamond Heating and Air.   We signed the contract with Bob Weatherford who is also the owner of Diamond Heating & Air.

Both my wife and I were especially impressed with Bob?s thoroughness in explaining the type of system we really needed, the SEER rating of the equipment, and the best way of replacing the existing outdated  heating and cooling system, inadequate insulation, and faulty duct installation.   These were all good suggestions in transforming our home into a more energy efficient and comfortable environment.   Also, it was pointed out that some of the existing ducts became loose and disconnected.  Fiberglass insulation was blowing into one of the rooms.  The outdated  ducts were installed many years ago, and were poorly installed, wasting lots of energy, and the duct work was hanging too low below the floor joists.  

Bob suggested that the new duct system be relocated and strapped contiguous to the floor joists which would allow us to walk underneath the house so we could better utilize the space for movement and storage.  Another big task involved the installation of new attic insulation.   This was a big job that required the knowledge that Bob has as being a Licensed Building Contractor.  

Again, the thing I appreciated the most was Bob?s honesty and the effort he made to make things right.  Bob and Elaine worked hard to qualify us for the SMUD low interest rate financing and qualify us for the rebates that SMUD and PG&E were offering.  This helped us tremendously in bringing down the costs of the project.    My wife and I are extremely happy that our home now has an excellent home energy assessment from SMUD and PG&E.  We expect that our annual electric savings will be significant.  We are very happy to recommend Diamond Heating & Air to our family and friends.

Everything with this installation was flawless.  Willy and his team were punctual, professional and extremely knowledgeable.  We are thrilled with the work performed by Willy, Matt and another tech (sorry, do not have his name).  Paul was our contact with Ray O. Cook Heating and Air.  He gave us all the information we needed to make a decision and was quick to respond to questions we had.  Within one week we saw Jeremy on an emergency call (within 45 min.) had an estimate, and installation.  We would highly recommend this company.

"Outstanding quality, especially in custom designing what is called a cricket flashing to go around a chimney, the corner of the house and a valley which all converged at the same point.
Once the old roof was off, we found approximately $1700 worth of dry rot that needed to be replaced.  I felt the crew, particularly Mike Gibbs, did an excellent job of helping me understand the problems and then pick the best solutions to correct the problems.  Their price for the extra work was extremely fair and the again the quality was excellent.  We ended up replacing all of the fascia boards and the final result looked better than the original (and it was Mike's idea of how to do it).
In addition to the roof, they blew in some additional insulation in my two level attic to bring it up to an R-38 rating.  There were two spots that I felt might have been just a bit short and they returned promptly and filled in those spots by hand ... no questions asked.
For what it might be worth, the building inspector, when I told him the work was done by Brazil, sort of muttered under his breath "Good, they do it right" as he climbed the ladder to look at the roof.

"Right from the get go Brian was very helpful. He was very up-front and patiently explained all the kinds of insulation and suggested which ones to use. He even went so far as to include the inside wall insulation for soundproofing at no cost since the project was large. Very easy to work with and flexible."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"we were very impressed with out solar endeavor. The installers came when they said they would and finished their job within the same day. We added insulation to our attic to reduce our heating and cooling for the house and replaced 2 old windows . All the guys were great from Idan who evaluated our home, office staff and installers. We are very happy. "

"An unanticipated extra expense, but they removed all attic insulation and pumped in new insulation with 3X the protection. Closed up all possible entrances into house; made three trips. So far, no signs of these pests, but they say call anytime if I see signs. I'm moving and I can't -- with good conscience -- sell this house to others knowing it had rodents, although it didn't seem to bother the people I bought the house from."

Insulation FAQs, answered by experts

If you’re a savvy DIYer around the house, own the basic tools, and have enough time on your hands, you can definitely install fiberglass insulation yourself. Doing the work yourself will certainly keep overall insulation costs down. However, if you’re not confident in your handy skills around the house, call in a professional.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.

Opting for insulated ducts can lead to significant long-term savings on your energy bills and contribute to a more efficient HVAC system. The precise amount you can save depends on various factors, including your climate, usage patterns, and the insulation's quality. However, on average, insulated ducts can result in savings of up to 20% on your annual heating and cooling costs, according to ENERGY STAR®.
