Top 7 HVAC companies in Clark, Nevada

Climate

Clark County sits in IECC zone 5B with a dry moisture regime. Las Vegas records a winter design temperature of 33 °F and a summer design temperature of 108 °F. Heating degree days total 2,800 while cooling degree days reach 2,200, producing a balanced mixed load profile. The very low latent load means humidity control is rarely the dominant sizing factor. Central air conditioning saturation is near universal and peak service demand occurs in summer. Equipment must handle extreme cooling loads and wide daily temperature swings; proper duct placement in conditioned space versus attics therefore affects efficiency more than in many other markets.

The shortlist

This shortlist is built from public listing data, not a review of work performed. Companies are ranked by Bayesian-adjusted rating that pulls each star rating toward the national mean of 4.764 until review volume is sufficient for the raw score to stand alone. Small tie-breakers favor a public website, HVAC-specialist listing category and published 24/7 availability.

Loyalty Plumbing & Air

Loyalty Plumbing & Air operates from 6320 S Sandhill Rd Unit 10, Las Vegas, NV 89120 and lists a 5-star rating from 31 reviews. Its adjusted score of 4.944 sits 0.18 above the national mean after the pull from limited review depth. The firm appears as a general contractor with published 24/7 availability and a public website. These signals place it first. The numbers cannot reveal whether the 31 reviews cover recent work or whether the 24/7 listing reflects actual staffing levels year-round. Phone: (702) 903-7223.

Five Star Mechanical

Five Star Mechanical is located at 6250 S Mountain Vista St H2, Henderson, NV 89014 and holds a 5-star rating from 23 reviews. Its adjusted score of 4.926 reflects a 0.162 pull toward the national mean of 4.764 given the modest review count. The listing shows a general contractor offering 24/7 service and a public website. Those factors secure second place. Review volume remains too low to confirm consistency across multiple seasons. Phone: (702) 550-0380.

Heavenly Air Conditioning and Heating LLC

Heavenly Air Conditioning and Heating LLC lists 35 reviews at a perfect 5-star raw rating from its address at 6295 Harrison Dr #1, Las Vegas, NV 89120. The adjusted score of 4.911 is 0.147 above the national mean; the larger review count reduces the pull compared with smaller peers. It appears as a general contractor with 24/7 availability but no public website. The absence of a website accounts for its third-place position. The figures give no indication of how many of the 35 reviews involve full installations versus service calls. Phone: (702) 600-1088.

Callidus Air - Henderson HVAC Contractors | Air Conditioning, Cooling, & Heating

Callidus Air records a 4.9-star rating from 34 reviews at 1010 N Stephanie St #2, Henderson, NV 89014. Its adjusted score of 4.896 sits 0.132 above the national mean. The raw rating already lies above the mean, so the adjustment moves it downward modestly. The firm lists as a general contractor with 24/7 service and a public website. These elements place it fourth. The data do not show whether the 4.9 rating includes commercial or only residential projects. Phone: (702) 467-0562.

Trusted Paradise HVAC Services

Trusted Paradise HVAC Services holds a 5-star rating from 10 reviews at 313 Orville Wright Ct, Las Vegas, NV 89119. The adjusted score of 4.863 is 0.099 above the national mean; the small review count produces a larger pull. It appears as a general contractor with a public website but no published 24/7 availability. That combination determines fifth place. Ten reviews leave open the possibility that performance varies outside the sampled jobs. Phone: (725) 349-4851.

HVAC Connection LLC

HVAC Connection LLC shows a 5-star rating from 9 reviews at 5760 Douglas Everett St, Las Vegas, NV 89120. Its adjusted score of 4.858 sits 0.094 above the national mean, with the limited sample size driving most of the adjustment. The listing is a general contractor with a public website and no 24/7 claim. These signals fix sixth position. Nine reviews supply too narrow a base to judge long-term reliability. Phone: (702) 420-3723.

Las Vegas Air Conditioning and Heating

Las Vegas Air Conditioning and Heating lists a 4.9-star rating from 21 reviews at 2819 Calle Del Oro, Las Vegas, NV 89120. Its adjusted score of 4.82 is 0.056 above the national mean. The raw rating already exceeds the mean, so the adjustment lowers it slightly. No website or 24/7 listing appears. These factors place it seventh. Twenty-one reviews still leave room for seasonal or project-type variation not captured in the aggregate score. Phone: (725) 433-1080.

How to choose

Verify current NSCB license status on the public search page before requesting quotes. Confirm the contractor participates in NV Energy programs if utility rebates are planned. Ask about duct location relative to conditioned space, given the 108 °F summer design temperature. Request references from recent full-system replacements rather than service calls alone.

Cost

Installed costs for a full system range from $8,900 to $10,900 according to one data set, while 2025 invoiced averages reach $23,650 with an upper quartile of $33,628. The 2.4× spread between sources remains unexplained by the published figures. Labor is listed at $115 per hour and permit fees fall between $100 and $400. Clark County sits at average cost tier versus national benchmarks.

Licensing and permits

The Nevada State Contractors Board issues C-21 Refrigeration and Air Conditioning licenses for full residential and commercial work, C-21B for residential-only, C-1D for warm-air heating and air conditioning, and C-1 for plumbing and heating. A cash or surety bond plus workers’ compensation insurance is required; bond amounts are set case-by-case. NSCB licensing is statewide for work above $1,000 in labor and materials. Mechanical permits for furnace or AC replacement are issued separately by Clark County or municipal building departments.

Incentives

The Nevada Home Energy Rebates program is conditionally approved with a planned $8,000 heat-pump rebate. NV Energy offers $300–$1,500 utility rebates but requires use of a participating contractor. No state tax credit exists. Federal 25C and 25D credits expired at the end of 2025; only the commercial 48E ITC remains available under strict timing rules. Homeowners seeking rebates must therefore select from the utility network rather than any licensed firm.
