Expert Furnace Service and Repair

When your furnace shows signs of trouble, our factory-trained technicians respond quickly to diagnose and resolve the issue. We carry a comprehensive inventory of parts on our service vehicles, enabling us to complete most furnace repairs in a single visit. Now operated by Regis J.

Heating System Installation and Replacement

Whether you need a new heating system installation or it’s time to replace your aging furnace, our experienced team guides you through the selection process. We consider factors like:

  1. Home Size and Layout: Determining the optimal system capacity
  2. Energy Efficiency Requirements: Meeting your budget and environmental goals
  3. Comfort Preferences: Matching your specific heating needs

Preventive Maintenance Programs

Regular maintenance extends system life and prevents costly breakdowns. Our comprehensive maintenance program includes:

  • Safety Inspections: Carbon monoxide testing and heat exchanger examination
  • Performance Optimization: Cleaning and calibrating system components
  • Seasonal Preparation: Complete system readiness check before winter

Emergency Heating Repair

Heating system failures don’t follow a convenient schedule. That’s why we maintain 24/7 emergency repair services throughout Greensburg, Latrobe, and Irwin, PA. Our technicians arrive equipped with diagnostic tools and common replacement parts to restore your heating system quickly and efficiently.

Professional Heater Installation

Proper installation is crucial for optimal heating system performance. Our installation process ensures your new system operates at peak efficiency from day one. We take time to properly size and configure your system, considering factors like ductwork condition, insulation levels, and local climate patterns.

Signs Your Heating System Needs Attention

Don’t wait for complete system failure before scheduling service. Watch for these warning signs:

– Unusual noises during operation
– Inconsistent heating throughout your space
– Rising energy bills without increased usage
– Frequent cycling on and off
– Poor airflow from vents
– Yellow pilot light instead of blue
– Unusual odors when running

Early intervention often prevents more expensive repairs later. Our diagnostic expertise, developed since our founding in 1962, helps identify potential issues before they become major problems.
