Well new furnance installed in Feb 2019. Could not get humidifier to run. Certain it was mechanical problem. Call Selega and they set me up pretty quick for service. How embarrassing it was operator error. Chris was very understanding and took time to explain how to correcly operate my humidifier. Chris, my cats are not ducking me when I try and pet them the static is gone now with moist air.😀

We trust and treasure our Seliga Team, especially, Wayne Glore, who we are lucky to have visit at least twice a year.
He takes very good care of us and our heating and cooling.
We feel safe and confident that he and they are the best for us.
And we are thankful for them.

Seliga Heating and Cooling were excellent from proposal to the finished job... Thanks Jeramie, Dan and Mike. My entire experience was great.

We had several quotes when our AC unit started to decline and Seliga Heating and Cooling came highly recommended.  We were looking for a quality system as opposed to the least expensive system and chose Seliga Heating and Cooling to install an American Standard system.  The results were greater than expected and we are now saving $100 - $150 per month on utilities with the new system. After the rebates and utility cost savings, the unit is paying for itself. I would definitely recommend Seliga Heating and Cooling for any HVAC needs.

Just had a new furnace installed. Greg and Wayne were absolutely the best. Greg was here at 7:30 in the morning and Wayne very shortly thereafter; they didn't stop working for 12 solid hours and did a fantastic job. Greg and Wayne were two very competent and professional technicians. Wonderful job. Thank you.



I'm not just pleased, but very...

I'm not just pleased, but very pleased with the work completed at my home. A job well done and timely. Seliga arrived early and went right to work. Installed a water heater and hooked up a furnace on the day that was scheduled. Finished on time the same day:)
