I had a problem with my unit fan outside not running, and they came the same day, probably less than 2 hours after I called. They replaced a capacitor and I was up and running. They also offer a service plan that you can purchase for under $25/mo that gets a visit twice a year to prepare/test the heater for the winter and a change of the filter and then again in the spring before summer for the same service for the a/c system. They contact you to set up both visits. I highly recommend them. read less

They guarantee inspection pass. They offer bi-annual maintenance (spring and fall, for a monthly fee) and will contact you before these times to schedule the appointments. The systems have worked really well. They also offer plumbing services if needed because they are licensed. read less

Janice, Scott, Tim and Zac are very knowledgable and responsive, more so than some other HVAC folks in the area that I had used prior to discovering SG. They provide me a level of confidence and peace of mind that I have not before experienced. They have replaced 1 HVAC system, 1 gas-fired hot water heater, 2 bathroom faucets and will shortly be installing a replacement HVAC system for the lower floor of my home. Their installations, as well as their maintenance, is excellent. read less

I called on a weekend because I was having issues with my old furnace that they installed back in 2005. The temperature outside was 17F so I needed a quick answer from them. I left a message and the owner, Scott Greiff called me back in no time. I explained in detail what the problem was and he quickly identified the root cause of the issue. Rather than charging me hundreds of dollars for an emergency weekend visit, he stayed on the phone with me for almost an hour. He patiently explained me step by step how to fix the problem with a high-pressure switch and a clogged condensate trap. Scott guided me on the phone so that I cold fix the furnace quickly. The furnace is running perfectly again. I will certainly do business with them again in the future. read less

I was candid with the urgency of my plumbing need and they scheduled accordingly. The three relatively small plumbing needs were attended to by SG's technician Jaime, who was timely, professional, courteous, efficient and always cleaned his work station during the repairs. A chronically leaky stall shower required a new inner cartridge, and the two sink faucets did require adjustments to water restrictors as well as flexible connectors replacements in order to get the water flowing like it did years ago. Labor & materials are consistent with the world we now live in, but at least SG's service exceeds expectation. read less

As it turned out, the issue was with my fuse box. The technician was professional, knowledgeable, and thorough. The individuals who both made my appointment and called me regarding it were responsive, courteous, and understanding. As it turned out, I was not even charged for the service call and repair. I highly recommend SG to anyone who requires either installation or repair on their heating or air conditioning systems. read less
