Gas Heating Systems
Gas Furnace Options for Your Home
Not every gas furnace fits every house. Efficiency level, venting, and the state of your ductwork decide which option works for you.
Standard efficiency
Standard Gas Furnaces
A dependable, budget-conscious choice for homes already set up with conventional venting and a solid duct system.
Lower upfront investment · Uses existing venting in many homes
High efficiency
High-Efficiency Condensing Furnaces
These units capture more heat from each cubic foot of gas, which lowers fuel use over the heating season.
Lower monthly gas consumption · Requires a condensate drain line
Dual-Fuel System
Gas Furnace with a Heat Pump
The heat pump handles milder weather and shoulder seasons; the furnace takes over during the deepest cold.

Our Process
How We Diagnose and Repair Your Furnace
Our technicians check safety, identify the cause of the problem, and explain the available options. Work begins only after you approve the recommended service.
Stage 1
Inspect the Furnace and Check Safety
We confirm the reported problem, inspect the vent and flue, check for gas odours or combustion issues, and assess access to the furnace.
Stage 2
Test Furnace Components
We check the ignition system, burners, flame sensor, limit switches, and blower to identify the cause of the problem.
Stage 3
Explain Your Options
We explain our findings and discuss suitable repair or replacement options, including the expected costs of parts and labour.
Stage 4
Test Performance
After your approval, we complete the service and check furnace operation, heat output, airflow, and carbon monoxide levels.
Before You Schedule
A few details help us prepare for your visit.
- Your furnace’s age and brand
- When the problem started and how often it occurs
- Whether the furnace uses natural gas or propane
- Where the furnace vent exits the home
Furnace Repair
Signs Your Furnace Needs Repair Now
A furnace rarely dies without warning. These are the symptoms that most often lead a homeowner to call us for repair.
Furnace Won't Light
The blower runs but no flame appears. A dirty flame sensor, a worn igniter, or a faulty gas valve is usually the reason.
Warm Air That Stops Early
The furnace cycles off before the house reaches setpoint. Restricted airflow or a limit switch fault often causes this.
Frequent Short Cycles
Starts and stops every few minutes wear out components and waste gas. Overheating from a dirty filter is a common trigger.
Gas Smell or Burning Odor
Leave the area and call your gas utility from outside. Burning dust on the first run of the season is normal, but a persistent smell is not.
Loud Bangs at Startup
A delayed ignition can produce a sharp bang. It isn't safe to ignore, because it stresses burners and the heat exchanger.
Rising Gas Bills
If your furnace uses more gas for the same warmth, it's losing efficiency. Dirty burners and worn parts are typical causes.
Carbon Monoxide Alarm Going Off?
Get everyone outside into fresh air and call 911 or your fire department. Stay out until the home is cleared, then call us for an inspection of the furnace and venting.
Furnace Replacement
When Repair Stops Making Sense
Most furnaces deserve a repair before they deserve a replacement. Consider replacing your furnace if:
- It has reached the end of its expected lifespan.
- Breakdowns and repair costs are becoming more frequent.
- The heat exchanger is damaged, or a serious combustion fault is found.
- Gas bills keep rising despite regular maintenance and unchanged heating needs.

Frequently Asked Questions
Is It Time to Replace My Furnace or Can It Be Repaired?
It depends on the furnace’s age, how often it has needed repairs, whether it still heats every room evenly, and what a repair would cost relative to a new unit. We inspect the system and walk you through both options before recommending anything.
How Long Does a Residential Gas Furnace Last?
Many gas furnaces run reliably for well over a decade with regular service. Age matters, but condition, repair history, and combustion safety results matter just as much.
Do You Handle Emergency Furnace Repair at Night or on Weekends?
Yes. AC&R answers calls 24 hours a day, every day, across Northeast and North Central Pennsylvania. Call 570.788.2427 whenever the heat stops.
What Should I Do if My Carbon Monoxide Alarm Sounds?
Move everyone outside to fresh air and call 911 or your fire department. Do not go back inside until it has been cleared. After that, call us so a technician can inspect the furnace, venting, and heat exchanger.
What Is Included in a Furnace Maintenance Visit?
A maintenance visit covers combustion and safety checks, burner and ignition inspection, flame sensor cleaning, blower and airflow review, control testing, and a heating performance check. You receive a written summary of the findings.
Do You Install Gas Lines and Venting for New Furnaces?
Gas line and venting work connected to a furnace installation is performed by our licensed technicians, who test for leaks, confirm proper connections, and follow local code and manufacturer requirements.
