"Mid-July through August in San Antonio and South Texas can be brutally hot, and it was and still is in 2020. On a 105 degree Wednesday in mid-July, our air conditioning went out. Not good. With the pandemic, the heat and our age (over 70), we needed help quickly. After a very bad experience with a different contractor, we called 1st Choice Heating & Air Conditioning. They reacted to our situation the next day and scheduled a crew for a full replacement system to be installed on Friday morning. They're pricing was fair (and less that the other contractor), and they did not try to take advantage of us for the expedited service. We found 1st Choice to be highly professional, meticulous in the installation and very customer centric -- very straight forward. They've called several times afterward to make sure the system was functioning properly and that my wife and I are happy. Very refreshing in today's business environment. We highly recommend 1st Choice Heating & Air Conditioning. A+ in our view. Jerry G"

"Wow! This business was recommended by a friend. I had a quote that I was comfortable with but decided to make just one more call. I am very glad that I did because they came out quickly and fixed my roof leak on the spot for 1/4 of the cost of my original quote to the penny. I have recommended them to a bunch of other people already and keep their contact information in my phone just in case I need them again. Well done, thank you!"

FAQs for insulation service projects in San Antonio, TX
When choosing a professional insulation installer, consider asking these questions to determine the best fit.
Will you address air leaks in my house?
Can you provide an R-value (heat resistance) fact sheet?
What kind of insulation will work best for my home?
How do you handle signs of a water leak?
Are you licensed and insured?
Can you provide customer references?
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
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.
In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:
High heating and cooling bills
Uncomfortable room temperatures
Ice dams on the edge of your roof
Roof leaks
Cold floors and walls
Freezing pipes
Temperature fluctuations
Visibly low insulation
Noise problems
Pest problems
On average, insulating an attic costs about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:
Blown-in: $1–$4 per square foot
Spray foam: $2–$5 per square foot
Batt: $2–$4 per square foot
Structural insulated panels: $4–$7 per square foot
Loose-fill: $2–$5 per square foot
Reflective: $0.50–$1.50 per square foot
