Lennox International, Inc., makes heating, ventilating, and air conditioning (HVAC) systems. T & M Solar and Air Conditioning, Inc., installs HVAC systems in California. T & M became interested in Lennox solar panel systems because Lennox advertised that the systems could run through an existing HVAC system, rather than through an electrical panel. This meant that the systems, unlike traditional solar panel systems, could be installed without modifying the electrical panels in a residence. Lennox representatives repeatedly assured T & M that their systems would operate as advertised. T & M ordered and paid for six Lennox systems for customers. The systems could not be operated or installed as promised, however, and T & M ultimately had to remove them from customers' homes at its own expense. T & M sued for breach of an express warranty. A federal court found that T & M had ordered the Lennox systems precisely because they could operate through an HVAC system without modification of existing electrical panels. That was sufficient evidence of reasonable reliance to justify a trial.

Note: Can you please answer this question using IRAC( Issue, Rule of Law, Analysis, and Conclusion) format. Because then it will be easy for me to understand the case a a lot better.
