Claim This BusinessIrish Heating and Air Conditioning LLC operates from Modesto and extends service throughout the Central Valley, including Tracy, Turlock, Manteca, Mountain House, and Stockton. The company holds NATE and EPA certifications for its technicians and provides both residential and commercial HVAC solutions. With 21 customer reviews averaging 4.2 stars, the contractor has built a presence in San Joaquin and Stanislaus counties. The business offers Saturday appointments and maintains service hours Monday through Friday from 7AM to 5PM.
The company distinguishes itself as a Mitsubishi Diamond Contractor Elite, enabling access to specialized ductless systems and exclusive financing through Synchrony, including potential rebates up to $500 on new installations. Unlike many area contractors, Irish Heating provides mobile warehouse-equipped service vehicles that allow single-visit completions for most jobs. All new system installations receive a 10-year parts and labor warranty, while standard repairs include a 1-year coverage. The company also maintains a 10% discount for military personnel and seniors, reinforcing its community-focused approach.
Customer experiences highlight specific technician responsiveness. A reviewer from Lathrop noted technician Ryyan Murphy arrived same-day during extreme triple-digit temperatures, resolving an AC issue quickly. However, two detailed reviews reflect significant challenges: one customer reported a system failure within a year with no company response despite multiple calls and messages, while another described a $40,000 Mitsubishi installation that failed in October 2024 with over 20 unanswered service requests. These accounts suggest variableservice quality depending on technician assignment and timing.
Of 21 reviews, 15 customers award 4 or 5 stars citing same-day service, thorough diagnostics, and clean worksite practices. Two 1-star reviews from 2024 describe unresponsive customer service after system failures, with one customer unable to reach the company despite multiple phone calls and the other reporting 20+ ignored service requests. The disparity between quick-resolve positive experiences and unresolved warranty claims indicates inconsistency in post-installation support.
