Top 7 HVAC companies in St. Joseph, Indiana

Public listing data for St. Joseph County, Indiana, yields seven HVAC contractors ordered by Bayesian-adjusted star rating. The adjustment pulls every raw rating toward the national mean of 4.764 so that small samples do not dominate. Three firms operate with public websites and one advertises 24/7 service; all but one list a phone number. Installed costs appear in two sources that differ by several thousand dollars, and Indiana leaves licensing and permitting to each city or county. The climate is heating-dominant, with winter design temperatures near 3 °F and 5,400 heating degree days.

How to choose

Review count, raw star rating and the Bayesian-adjusted score determine rank order. A public website and published 24/7 availability serve as tie-breakers when scores are close. Every contractor must still be checked directly for current insurance certificates and local permit compliance because the state issues no HVAC license.

The shortlist

Thrice Mechanical Services

Thrice Mechanical Services holds 18 reviews at a raw 5.0 that the ranking adjusts down to 4.853 because the national mean sits at 4.764 and 18 reviews are still modest. The firm lists its address as 890 Industrial Pkwy, North Liberty, IN 46554 and can be reached at (574) 804-2299. Its general-contractor category and lack of 24/7 notation suggest standard daytime scheduling. The modest downward pull reflects the limited sample size. These numbers do not reveal whether the 18 reviews cover furnace or cooling work.

Cressy Heating and Cooling

Cressy Heating and Cooling shows 13 reviews at a raw 5.0 adjusted to 4.835. The address is 200 N Church St Ste 200, Mishawaka, IN 46544 and the phone is (574) 271-4060. Listed as a general contractor without round-the-clock hours, the firm receives the same modest downward adjustment as the leader. The smaller review count produces a slightly larger pull toward the mean than the first-place entry. The figures give no detail on recent project types.

Allegiant Heating & Cooling

Allegiant Heating & Cooling records three reviews at a raw 5.0 adjusted to 4.785. Its address is 23978 IN-2, South Bend, IN 46619 and the phone number is (574) 282-2665. The general-contractor listing and absence of 24/7 availability place it behind the two larger samples despite the identical raw score. The adjustment moves the rating farther because three reviews carry even less weight. Nothing in the numbers confirms service area coverage inside St. Joseph County.

Morgan HVAC Repair

Morgan HVAC Repair lists one review at a raw 5.0 adjusted to 4.772. The address given is 2301 N Bendix Dr #911, South Bend, IN 46628; no phone number appears in the listing. Its general-contractor category is offset by published 24/7 availability, which supplies the tie-breaker that keeps it ahead of firms with lower raw scores. The single review produces the largest downward adjustment among the top four. The data cannot indicate whether emergency calls are actually answered.

All Temp Heating & Cooling

All Temp Heating & Cooling carries 25 reviews at a raw 4.3 adjusted upward to 4.553. The address is 3016 E Mishawaka Ave, South Bend, IN 46615 and the phone is (574) 277-4240. The general-contractor listing and website presence produce a modest upward adjustment because the raw score sits below the national mean. Twenty-five reviews give the rating more stability than the five-star entries above it. The numbers do not separate furnace from cooling jobs.

Johnstone Supply

Johnstone Supply shows 21 reviews at a raw 4.1 adjusted upward to 4.491. The address is 3220 Rosetta Pl Dr, South Bend, IN 46628 and the phone is (574) 288-2843. No category is listed, yet the public website supplies the tie-breaker used here. The adjustment moves the score upward because the raw rating lies below the national mean and 21 reviews provide moderate weight. The listing supplies no information on field installation versus supply-house services.

B.E.R Refrigeration, Heating, Cooling, Piping

B.E.R Refrigeration, Heating, Cooling, Piping records 19 reviews at a raw 3.8 adjusted upward to 4.39. The address is 205 Palladium Ave, St Joseph, MI 49085 and the phone is (269) 428-2711. The general-contractor category and website produce an upward adjustment because the raw score sits well below the national mean. Nineteen reviews limit how far the score can rise. The numbers give no indication of how often the firm crosses into Indiana.

Cost

Modeled typical full-system installs range from $8,100 to $9,900 while the 2025 invoiced average stands at $15,472 and the upper quartile at $24,416. Labor is stated at $100 per hour and permit fees fall between $80 and $300. The two cost sources differ by several thousand dollars; the invoiced average is roughly twice the modeled typical price. Both figures are labeled average relative to national benchmarks. Homeowners should request written quotes that itemize equipment, labor and permit costs separately.

Licensing and permits

Indiana maintains no statewide HVAC contractor licensing board. Each city, town or county sets its own requirements, and insurance minimums likewise vary by jurisdiction. The data note that Indianapolis requires a Certificate of Completion and Compliance after permitted work, but St. Joseph County rules are not recorded here. Permits are therefore a local matter. Verification of any local license, EPA 608 card and insurance certificate rests with the homeowner.

Incentives

The Indiana Home Energy Rebates program remains available in 2026 with heat-pump rebates up to $8,000 and HOMES rebates between $12,000 and $18,000. No state tax credit exists. Utility programs through NIPSCO and others offer $200-$1,000 but require participation in a contractor network. Federal 25C and 25D credits expired at the end of 2025; only commercial 48E credits survive under narrow timing rules. Homeowners must therefore confirm network status with any installer before proceeding.

Climate

St. Joseph County lies in IECC zone 5A with 5,400 heating degree days and only 1,100 cooling degree days. Winter design temperature is 3 °F and summer design reaches 90 °F under humid conditions. The load profile is heating-leaning mixed, so dual-fuel heat-pump systems are common. Equipment must be sized for the dominant heating load while still handling humid summer peaks; oversizing risks short-cycling in the short cooling season.

Public data provide only a starting point. Every contractor should be checked for current local compliance, references and written quotes before any commitment.
