EXCELLENT Based on 115 reviews Sky Hammond2025-04-17Trustindex verifies that the original source of the review is Google. Reached out for a second opinion because the company that installed our unit supposedly found over $2,000 worth of repairs on our 3-year-old ac unit. They were out here the same day I made the call, the parts that needed replaced were under warranty, so for 1/4 of the price we have ac again! I loved how thorough our tec was and will definitely be using 1st Gen in the future! Tracey Seymour2025-03-28Trustindex verifies that the original source of the review is Google. Mr. Domínguez came out promptly and deligently checked everything until he finally found a short as the bundle of wires went into the outside brick wall, it was very hard to get to but he found where friction had worn through the coating and wire and fixed it for a reasonable price, saving us thousands. This was after the first company I called, who was not here nearly as long, had told me we needed a new unit Thank you so much 1st Gen!!!

If your furnace is over 10-15 years old, requires frequent repairs, struggles to maintain consistent temperatures, or causes a spike in your energy bills, it may be more cost-effective to replace it rather than continue with repairs.
Furnace size depends on home square footage, insulation quality, and climate. We will assess your home’s heating needs to determine the right BTU capacity for optimal efficiency.
Routine furnace tune-ups and filter changes are essential for maintaining efficiency and extending the lifespan of your new unit. Annual professional inspections help identify potential issues before they turn into costly repairs.
