If you would like to schedule heating maintenance, call us or contact us online. Keep reading to learn about our heating maintenance services in detail.

Why Heating Maintenance Matters

Homeowners who schedule regular heating maintenance enjoy the following benefits:

  • Improved energy efficiency, and thus, lower energy bills
  • Extended equipment life
  • Protection from unexpected breakdowns, gas leaks, and carbon monoxide

These advantages add up to real peace of mind. When your system is cared for by professionals, you can count on steady warmth all winter while avoiding the stress of costly mid-season repairs.

What’s Included in Professional Heating Maintenance

A heater tune-up isn’t a glance at your equipment. It’s a meticulous inspection, cleaning, and calibration process. Allied’s experienced technicians follow a detailed checklist tailored to the type of system in your home. Below, you’ll find what’s typically included for furnaces and boilers, so you know exactly how we keep each working at its best.

Furnace Maintenance: What to Expect

Furnaces rely on precise airflow, ignition, and combustion to deliver even warmth throughout your home. Allied protects that performance with our 21-Point Furnace Inspection, a detailed process that checks every vital component for safety and efficiency. During your furnace preventative maintenance visit, we will:

  • Inspect the heat exchanger, burners, and ignition or pilot assembly
  • Clean and adjust burners for smooth, efficient combustion
  • Check the blower motor, lubricate moving parts, and verify belt tension if applicable
  • Examine the bypass damper or zoning controls if present
  • Test line voltage, capacitor, and relays to ensure proper operation
  • Verify gas pressure, airflow, and carbon monoxide levels
  • Tighten electrical connections and measure voltage
  • Clean condensate drains and safety switches
  • Calibrate the thermostat and confirm proper system cycling
  • Replace or clean filters and review airflow through ducts

By following this process, our technicians make sure every part of your furnace is ready for the heating season. Afterward, we’ll explain our findings and outline any steps to keep your equipment running safely and efficiently.

Boiler Maintenance: What to Expect

Boilers heat water and circulate it through pipes or radiators, so they need a slightly different approach. Our boiler maintenance service is designed to protect these hydronic systems from leaks, corrosion, and inefficiency. When you schedule boiler maintenance with Allied, we typically:

  • Examine the heat exchanger and burner assembly for buildup or damage
  • Inspect the circulation pump and lubricate as needed
  • Check water levels, pressure, and temperature controls
  • Test relief valves and other safety devices
  • Flush or bleed the system if sediment or air pockets are present
  • Review expansion tank performance to maintain balanced pressure
  • Inspect visible piping and radiators for signs of leaks or corrosion
  • Verify thermostat settings and overall system response

After the service, we’ll walk you through the results and suggest any preventive measures to avoid costly downtime.

How Often to Schedule Maintenance

Timing is key when it comes to caring for your heating system. Most manufacturers recommend professional service once per year, preferably before temperatures drop. A fall appointment ensures your furnace or boiler is ready for peak performance as soon as cold weather arrives.

There are also situations where you shouldn’t wait until your next annual visit. If you notice uneven heating, strange noises, or climbing energy bills, call us right away. Our emergency heating team can prevent small issues from escalating into major problems.

What Our Customers
Say About Us

We moved into a new house recently and Allied was recommended to us by my best friend.

We had them install a new humidifier and zone the system. On moving day (Friday) at 3 pm when we showed up we found the AC wouldn't shut off. I texted my tech with hopes of getting on the schedule for the following week since it was late Friday. He said someone would be there in 30 min. They stayed for 2 hours and fixed a faulty wire and it was all covered under warranty. Can't argue with customer service like that. Highly recommend if you want dependable folks that are very responsive.

We were extremely pleased by the service that Allied provided us.

Our A/C went out over the 4th of July we knew we needed a new system installed asap (we knew it was on its last leg). We contacted them and two other companies for comparison quotes. Allied was out here first thing July 5th to assess and provide a quote. In the end we decided to go with them. They were professional, thorough and very detailed in options and quotes.

Moved into the neighborhood and Allied HVAC had been recommended from my brother to replace both our furnace and ac unit.

Very professional from the start with a quote from Chris B. in sales which lead to an install date of my choice. On the day of the installation Jeff and Jackson arrived right on time as requested. The installation was prompt and done in a timely matter, and it they explained exactly what needed to be done from start to finish.
