Why SEER Ratings Matter More Than You Think

Understand the Value Before You Invest

SEER ratings (Seasonal Energy Efficiency Ratio) determine how much cooling you get per unit of electricity. Higher SEER = lower operating costs and greater efficiency. We help you compare options and choose the right balance of comfort and cost.

What Local Homeowners Are Saying

See how SumZero has helped local homeowners stay comfortable year-round with energy-efficient heat pump solutions.

We had a great experience with SumZero installing 6 minisplits and 2 condensers. Long story short, we initially went with a different HVAC company (never having met with SumZero), and that company strung us along for months (partly due to genuine supply chain issues). When installation day finally came they showed up and said they couldn't do the job. So back to the drawing board. We then met with 7 or 8 HVAC installers, most of whom we hadn't met with before. SumZero's quote was middle of the pack. Unlike everyone else who was fine maxing out the minisplit BTUs, SumZero very much cautioned against oversizing the units and now that I've learned more about these technologies I really appreciate their working to size the system correctly. They also split up our two zones in a smarter way than anyone else was proposing. The SumZero team that came on install day were among the nicest contractors we've worked with on any of our various house issues we've had. After install we were having a smell issue with a couple of our units. Our SumZero contact came by to check on the issue, and I so appreciated how he didn't try to gaslight me. The smell wasn't happening at first when he arrived and instead of saying "Well ok, I guess there's no issue!" he stuck around and seemed genuinely curious and motivated to figure out what was going on. He did eventually smell it. They sent their techs out promptly after that and discovered there was something that wasn't wired correctly that was causing units to fire at the wrong times which caused excess condensation, and they fixed it. For what it's worth, we discovered after picking SumZero's quote that some friends of ours used them and also had a good experience.
