Reliable Residential Backup Generators for Your Home

A permanent residential backup generator protects your home in greater Seattle-Tacoma automatically, giving you comfort, security, and convenience.

What are the advantages of an automatic standby generator?

An automatic generator provides multiple advantages over a portable one:

Why Automatic Standby Generators Are Safer Than Portable Models

The American Red Cross considers standby generators safer than portable generators because they don’t come with the risk of deadly carbon monoxide poisoning.

Cost

They are less expensive to run because the fuel source is natural gas or propane.

Convenience

They start automatically within seconds of a power outage, eliminating the need to haul a portable generator outside or run extension cords throughout your home.

24-7 Protection

Whether you’re home or away, they turn themselves on when power fails and then off again when utility power returns, so there is no need to monitor the unit during an outage.

 Backup Generator Installation & Maintenance

Professional Greater Seattle residential generator installation is essential to keeping your home comfort systems operating safely and efficiently. To this end, we offer several generator services to improve the life and quality of your equipment.

Allen Walker was knowledgeable, courteous, communicative, and personable. We learned good info about our one-year-old system and, in addition, about draining our hot water tank (which he also took care of). We felt assured that our equipment is in good hands; we highly recommend Allen and Home Comfort Alliance.

I was prepared to give HCA a 3 star review because of issues with the install, it taking us three weeks after install to get our permit and their controller somehow losing the money from our check that cleared to their bank. However, their installer Joseph Daniels saved the day, and without his help we would not have been happy with our purchase.
Joe arrived a week after install because our heat pump wasn't making the air hot or cold. Within five minutes Joe realized there was an incorrect jumper on the circuit board that essentially made the heat pump not function. We could immediately tell the heat pump was working immediately after the jumper fix.
Joe still stayed another 30 minutes and made sure the system was providing heating and cooling before leaving, and even gave us tips on how to best use the newly installed filter (we were not running the fan all the time). He also called someone at the company because we didn't receive our permit, which was supposed to be supplied before the installation date.
Joe went above and beyond. I'm a believer that if a company makes right on errors (which happen), all is well that ends well. The heat pump has been amazing. Thanks again, Joe.
