Your Family's
Comfort Is Our
Only Priority
We understand what it means when your heat goes out in the middle of a Pennsylvania winter. It's not just an inconvenience — it's a crisis. That's why we built our entire operation around one promise: when you call Conquistador, someone answers, and someone shows up.
No voicemail. No "we'll get back to you in 24-48 hours." A real person, a real technician, and a real solution — every time.
Don't Take Our Word For It
"I called at 11pm on a Sunday when my furnace died. A technician was at my house by 1am and had it running by 2. I've never experienced service like that from any company."
"We've been getting our heating oil from Conquistador for 8 years. The automatic delivery means we never run out, and the price is always fair. Wouldn't use anyone else."
"The technician who installed our new heat pump was professional, clean, and explained everything he was doing. The system has been flawless for two winters now."
