Be Careful of Cheap Fly-By-Night Heating Service
We’ve found systems dirty after service and they replace parts that work fine. Call a trusted heating contractor you can count on. Consumer Reports say choosing a contractor is your most important decision when replacing, even maintaining any heating system.
Is An Annual Furnace Tune-Up And Safety Inspection Necessary?
Furnace manufacturers recommend annual maintenance by a qualified technician. Warranties can state that any damage sustained to the unit due to a lack of regular furnace maintenance will not be covered in the warranty. Here are more reasons to maintain your heating.
Your Furnace Can Degrade 3% Every Year.
When components start to degrade, your system works harder to produce the same result. Stresses caused during the thousands of starts every year cause parts to wear out. Worst yet, your furnace’s life is shortened, and you spend more on utility bills. Order a heating check-up today to extend the life of your furnace.
Your Furnace Is A Dirt Collector.
Real dirt is the # 1 cause of higher utility bills and furnace breakdowns. Dirt compromises how well your system can perform. A furnace also forms rust over time, fittings get loose, and electrical components weaken after starting thousands of times a year.
80% of all HVAC repairs could have been prevented with routine heating maintenance. Regular heating furnace maintenance works.

What Does a PDM Furnace Tune-Up Include?
Our goal is simple: safe, efficient operation and wonderful indoor weather. A knowledgeable PDM technician will adjust, calibrate, and reset your system to factory specifications, giving you peace of mind and a safe night’s sleep.
Here is a detailed breakdown of our comprehensive inspection and maintenance process:
I. Safety & Fuel System Integrity
Inspect Fuel System: Inspect and test gas piping for dangerous leaks and emergency shut off valve operation.
Gas Valve & Pressure: Check the Gas Valve that adjusts heating output and measure the rated and actual gas pressure.
Combustion Safety Controls: Test the Flame Sensor and Pressure Switch—critical safety controls that guard against gas leaks and prevent furnace cycling failure.
Heat Exchanger Check for Cracks: We inspect this critical component for cracks that could leak deadly Carbon Monoxide (CO) gases into your home.
Exhaust Flue Check: Inspect the exhaust flue for proper venting, ensuring all toxic gases are safely removed.
II. Efficiency & Performance Optimization
Clean & Inspect Gas Burners: Dirt and rust cause poor combustion, potentially increasing your monthly utility bill by up to 15%. We clean the burner surface and check for proper combustion.
Ignition System Test: Check the entire system (including the Electrical Transformer) to ensure a reliable start-up, preventing unexpected system shutdowns.
Air Temperature Rise Check: Measure the temperature rise across the furnace to ensure it’s operating within the safe and efficient range specified by the manufacturer.
Heat Anticipator Calibration: Fine-tune the thermostat setting to prevent the furnace from cycling on and off too often.
Air Filter Inspection: Inspect the type and condition of your air filter. A dirty filter can reduce airflow by 65%, stress the furnace, and drive up energy costs.
III. Electrical & Blower System Reliability
Blower Motor & Bearings: Clean and lubricate the motor. Check motor volts and amperage for signs of strain.
Blower Wheel and Belt: Inspect for damage that can cause motor breakdown and reduced efficiency.
Capacitor Check: Test the capacitor, which stores the energy needed to kick the blower into action. A faulty capacitor can cause a complete furnace shutdown.
Temperature Sensor Control: Test the high-limit safety switch that shuts off the burner if the furnace overheats.
Wiring & Connections: Inspect and tighten all electrical wiring connections for safe and reliable operation.
