In Summerlin, the pricing for air conditioning services can fluctuate quite a bit, depending on what exactly is required. A simple maintenance visit or system tune-up will generally set you back about $75 to $150. If you need anything more than basic maintenance, like a minor repair, you're looking at prices between $150 and $500. If your A/C unit has serious issues, and we're talking about significant repairs or the need to replace major parts, then you're obviously going to pay a lot more—upward of $500, $1,000, or even $1,500. And what if you just need an entirely new system? A full installation or system replacement costs between $3,000 and $7,000, assuming you're sticking with the same size, efficiency range, and basic labor and parts situation. As a rule of thumb, it's best to get a few quotes before making a decision.
