"We had a pipe burst in our basement ceiling that led to an outdoor faucet, and we had to shut water off to our house. Custom came out less than 24 hours after I called. The crew sent a text message when they were in route and I could track them prior to their arrival. The crew was prompt and quickly identified the problem with minimal disruption to our existing building materials. They showed me the source of the problem and quickly repaired it.

FAQs for central a/c installation projects in Longmont, CO

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.
