We look forward to earning your business! We can make your home more comfortable and improve the quality of air you and your family breathe.

All the systems we install have the new environmentally friendly refrigerant that doesn't damage the ozone. We also are huge proponents of super high efficient equipment, such as 95% efficient furnaces. This equipment saves homeowners a tremendous amount in utilities.

"What: NOT Plumbing. Electrical wiring for/and installation of flood lights above garage door, side walkway to backyard, and backyard. Also installed porch light. Pros: On time, courteous Comments: Backyard floodlight was on all day & all night and on the same electrical source of the lights in the laundry room light and side walkway to backyard. The only way to turn it off was to turn off the electrical switch in the box, which turned off all 3 lights mentioned above. The flood lights were supposed to be on, with a timer, only during dark hours, but either it was on all night because they tied it to the laundry & walkway "wire" or electrical switch, OR they didn't put it on timer, or some other reason. They sent another team out to fix the issue within the next few weeks. Recommendation: Buy your own light fixture, inform YOU want to pick and have them install. Otherwise, they go with their own vendor and the alternative did not look anything like the style we wanted."

Central a/c installations FAQs

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.
