Thank you for choosing 411 Heating & AC, LLC, Contra Costa Countys premiere HVAC service professional. For nearly a decade, we've specialized in all your heating and air conditioning needs. We proudly serve Concord and the surrounding areas. We look forward to earning your business.
"Our heater broke and my husband is medically fragile and It was 58 degrees INSIDE. I needed help ASAP. He's 88 and I'm 77 and calling people was frustrating until I checked top Angie reviews for my area. Even then, two out of three failed on ability to respond in less than 7-10 days. Another said we can come assess in three days and then schedule your repairs. 411 came within hours and had us heating up with a brand new, quieter, and quicker system the next day! Can't thank them enough. And the pricing was very fair based on checking with others in our neighborhood and relatives who have had to replace their systems."

If you’re replacing an old AC system with a new unit, you can usually clean and repair the old ductwork without having to conduct a full replacement. Cleaning HVAC ducts typically costs around $400, while repairs range from $200 to $1,000. In contrast, installing new ductwork can range from $1,000 to $5,000, making it far more costly than cleaning or fixing existing ducts. HVAC installation costs an average of $7,000 to replace a full system, so staying on top of maintenance and repairs is important.
AC cost efficiency depends on the size of your space and your long-term plans for your home. If you only need to cool a small area, a portable AC unit has a low upfront cost. Heat pumps are typically the most cost-effective option if you want to cool an entire home or improve the resale value. They provide strong cooling while being energy-efficient, which saves you money on your utility bills compared to most other AC types.
Installing a central AC unit typically takes four to eight hours if your home already has ductwork in place. However, if new ductwork needs to be installed, this can add another one to two days of labor to your project.
