Customer Reviews
Air Temp
Being without heat for over a month (me being lazy and in denial) Luis was great!!!! Gave me a time range when he could stop by and updated me when he could arrive earlier. He "allowed" me to watch...
Luis is always available to come to the rescue! He is reliable and his fees are in line with other Peninsula services.
Refrigeration Repair pros. That's what they are!!! They fixed our commercial refrigerator on time for my business to re-open. Great service...
Maintech Service
Our water heater sprung a leak. Ron was able to diagnose and fix my problem the same day. He and his partner were efficient, meticulous and courteous. I would recommend Maintech without reservation.
Great communication, very easy to work with, flexible and a great team doing the work
I had three separate plumbing-related issues that needed fixing and these guys came and did a great job on all of them. Very personable technicians that give you a sense they truly care about their cl...
Consider Air Temp if...
- ✓ Your project specifically involves heating system repair or commercial refrigeration equipment, where Air Temp's specialized focus aligns with your needs
- ✓ You're located in San Mateo proper and want a contractor based directly in your city rather than neighboring Pacifica
- ✓ You need straightforward HVAC service without plumbing complications, and 19 years of licensed experience provides sufficient depth for your situation
- ✓ You value the ability to observe repair work and want responsive communication for heating emergencies
Consider Maintech Service if...
- ✓ Your project might involve both plumbing and HVAC work, such as water heater replacement, bathroom renovations with new fixtures, or heating systems connected to water lines
- ✓ You're seeking a contractor relationship that extends beyond a single service call, as customers report using Maintech repeatedly over decades
- ✓ The additional 14 years of licensed experience matters for your older home or complex mechanical system where hidden issues may emerge
- ✓ You prioritize fair pricing, thorough cleanup, and personable service alongside technical competence, based on consistent customer feedback patterns
Questions to Ask Before Hiring
- → Ask Air Temp whether your heating issue could involve plumbing components that fall outside their license scope, and how they would handle coordinating additional trades if needed
- → Ask Maintech Service about their current availability for projects in San Mateo proper, since they're based in Pacifica and you want to understand response times to your location
- → Request references from both companies for projects similar to yours in age and complexity, particularly if your home has older mechanical systems
- → Clarify each company's warranty terms and what follow-up service looks like if issues arise after initial work completion
The Bottom Line
For projects strictly involving heating systems or commercial refrigeration, Air Temp's 19 years of specialized experience and San Mateo location make them a solid choice with responsive service. However, Maintech Service is the stronger option for most homeowners due to their 33 years of licensed experience, comprehensive plumbing and HVAC capabilities, and proven track record across diverse project types. The ability to handle both plumbing and mechanical work under one contractor matters significantly when problems cross system boundaries or when you're building a long-term service relationship. If your project scope is clearly HVAC-only, contact Air Temp. If there's any possibility of plumbing involvement or you value the depth of 33 years experience, choose Maintech Service.

Frequently Asked Questions
For straightforward furnace repairs on newer systems, both veteran contractors have sufficient experience. The gap becomes more meaningful if your furnace is older, connected to complex ductwork, or if the problem is difficult to diagnose. Maintech's additional 14 years means more exposure to unusual failure patterns and legacy equipment that's no longer manufactured.
Water heater work typically requires plumbing licensing, which Maintech Service carries but Air Temp does not based on their HVAC and refrigeration focus. If your project involves water heater replacement or repair, Maintech can handle it directly while Air Temp would need to coordinate with a licensed plumber. Confirm this directly with Air Temp when you call.
Both serve the Peninsula area, but Air Temp is based directly in San Mateo while Maintech operates from Pacifica. For emergency service calls, the San Mateo-based contractor may arrive slightly faster to San Mateo addresses. However, Maintech customers report prompt response times despite the Pacifica location, so ask each company about their typical response window for your specific address.
Maintech Service is the clearer choice for ambiguous situations because their licensing covers both plumbing and HVAC systems. They can diagnose and address issues that cross between these systems without coordinating multiple contractors. Air Temp would need to identify whether your problem falls within their HVAC scope or requires bringing in a separate plumber, potentially extending your timeline.

How We Compare Contractors
License Verification
All license data is sourced from official California CSLB records and verified regularly.
Review Analysis
Customer reviews are aggregated from Google and analyzed to identify patterns in service quality.
Detailed Comparison
We analyze credentials, insurance, experience, and feedback to highlight meaningful differences.
Not all licensed contractors are created equal. While a valid license is the baseline requirement in California, contractors can vary significantly in experience, insurance coverage, and customer satisfaction.
- Experience matters: A contractor with 15+ years of experience has likely encountered and solved problems that newer contractors haven't faced yet.
- Workers' compensation protects you: If a contractor without workers' comp insurance has an employee injured on your property, you could be held liable.
- Reviews reveal patterns: Individual reviews can be misleading, but patterns across many reviews often reveal a contractor's true strengths and weaknesses.
- Bond amounts vary: A contractor's bond provides financial protection if they fail to complete work as agreed. Higher bonds offer more protection.
Taking time to compare contractors on these factors can save you from costly mistakes and help ensure your project is completed by a qualified professional.
