They were the only one who suggested measuring our house to see if our system size was right for our house. As it turned out, a 2.5 ton was more appropriate than the 3 ton we had been using.

Warning: Review Coercion & $1,100+ Pricing Discrepancy…read more I used Santa Air for five years and recommended them to many friends. Unfortunately, their business model has changed from "honest and hardworking" to "opaque and manipulative." The Technical Issues: In 2020, Santa Air installed my trane system but failed to properly connect the emergency heat strips. I spent five winters wondering why my house wouldn't stay warm below 30°F. They missed this mistake during every subsequent maintenance visit over the 5 years. Recently, they tried to charge me $1,700 for repairs I didn't need. A second opinion confirmed their diagnosis was wrong; that technician fixed Santa Air's original installation mistake and the actual sensor issue for a total of $575. The Billing Issues: Their current pricing "tiers" (Bronze, Silver, Gold) are incredibly over-inflated compared to other local HVAC companies. And if you only need a repair included in the Gold tier, you have to pay for all the things you don't need in the tiers below it. When I realized the invoice was vague and the work wasn't needed, I cancelled. The Ethics Issue: The most disappointing part was the office's response. They tried to emotionally guilt-trip me. They held my refund hostage, telling me they would only return my money if I removed my negative reviews. I refused to be coerced and had to fight for three months through my bank to recover the funds for services never rendered. Don't let the high star rating fool you--they are actively pressuring customers to delete bad experiences. Always get a second opinion!!!

Last year there was an issue with a part that should have been under warranty which cost me $2500 in labor costs. To avoid this I was sold an extended warranty, this year the AC unit stopped working again. The excuse I was given was that the panel is in the sun. The panel has been in the sun since the house was built. Terrible customer service and it seems like they aren't sure what they are doing. I wouldn't recommend. They even went so far as to charge me service fees without my authorization for something they didn't even fix. AVOID THIS COMPANY AT ALL COSTS

He looked at it and had to add 2 lbs. to the unit and said it had a slow leak in it, but it did not need replacement just yet, maybe in about 2 or 3 years. Dave was on time and fixed everything that needed to be fix and explained the health of both furnaces and AC units. Good work and trust in a company is hard to come by.
