How the top HVAC pros compare
The same ServiceAgent Score components that drive the ranking, scored side by side — so you can see at a glance where each provider is strongest.
The criteria we scored against
- 1. Trust (data & verification). Owner-verification, completeness of contact info, and review-volume credibility.
- 2. Recommendation (rating). The Google star rating, Bayesian-shrunk toward the category mean so a few 5-star reviews can't dominate.
- 3. Review depth. How many public reviews back the rating — more reviews, more reliable the signal.
- 4. Score confidence. How much data stands behind the composite score for this provider.
| Provider | Trust (data & verification) | Recommendation (rating) | Review depth | Score confidence |
|---|---|---|---|---|
| Around The Clock HVAC | Strong | Strong | Strong | Strong |
| Next HVAC and Appliance repair | Strong | Strong | Strong | Strong |
| San Francisco Expert Heating and Air | Strong | Strong | Moderate | Strong |
| Acosta Heating & Sheet Metal | Moderate | Strong | Limited | Limited |
| BEST CHOICE HVAC, INC | Moderate | Strong | Limited | Limited |
| Associated Heating of San Francisco | Moderate | Strong | Limited | Limited |
| Inner Sunset Top Heating and Air | Moderate | Strong | Limited | Limited |
| Air Flow Pros Heating and Air Conditioning | Moderate | Strong | Limited | Limited |
How we chose these
Same scoring engine as the main San Francisco hvac ranking, with an additional filter step: we look for Replacement signals in each provider's business categories, service tags, and recent review text.
When the Replacement filter would surface fewer than five providers, we fall back to showing top-rated hvac pros generally - they are far more likely to handle replacement work than an unrated provider would be.

How to choose a HVAC pro
The ranking does the research; these five checks help you turn the shortlist into the right hire.
- 1
Start with the top of the ranking, not an ad
The providers ranked highest in San Francisco earned it on review depth, rating, and data completeness — not on ad spend. Shortlist two or three from the top before you start calling.
- 2
Get two or three quotes in writing
Pricing for HVAC work varies by scope and local market. Written quotes from a few shortlisted pros let you compare apples to apples and spot an outlier before you commit.
- 3
Read the most recent reviews, not just the average
A strong average can hide a recent slide in quality. Sort reviews by newest and look for how the business handles problems — a thoughtful reply to a bad review often tells you more than the star count.
- 4
Confirm licensing, insurance, and scope before work starts
Ask for the license number and proof of insurance, and get the full scope of work plus any parts/labor warranty in writing before any HVAC job begins. Verify the license on your state board if the work is significant.
- 5
Match the provider to your actual job
A high-volume operator is great for a routine job; a smaller specialist may be a better fit for an unusual one. Use the scorecard above to pick for your situation, not just the overall rank.

What to know about hiring HVAC
HVAC work ranges from a quick repair to a full system replacement, and the right pro depends on the job.
What drives the price
System size (tonnage), SEER efficiency rating, ductwork condition, and whether it's a repair, replacement, or new install.
What to check
EPA 608 certification, manufacturer certifications (Trane, Carrier, Lennox), and whether they do a load calculation rather than just swapping like-for-like.
When to call
Before peak summer or winter — emergency and after-hours work costs more, and the best crews book out in heat waves.
