Signs You Need Heating Repair

Many homeowners aren’t sure when to call for professional heating repair. Ignoring early warning signs often leads to bigger, more expensive problems down the road. Paying attention to your furnace or heating system’s behavior can save you money and protect your family’s comfort.

Here are some of the most common indicators that it’s time to call Allied:

  • Rooms that never seem to warm up
  • Unexplained spikes in energy bills
  • Strange noises like banging, rattling, or squealing
  • Short cycling or constant running
  • A yellow pilot light or frequent ignition issues

If you notice any of these red flags, don’t wait until your system stops working entirely. Addressing the issue early ensures faster, more affordable solutions. It also prevents uncomfortable nights without heat. Allied’s team is just a call away to provide reliable heating system repair when you need it.

Types of Heating Equipment We Repair

There are several different types of heating systems, and they each require specialized knowledge to repair. At Allied, our technicians are trained across all major equipment types to deliver the right fix quickly and effectively. Primarily, we repair furnaces, boilers, and heat pumps.

Furnaces

Our team has the training and equipment necessary to repair both gas and electric furnaces. From ignition issues and blower motor failures to airflow blockages and thermostat malfunctions, we’ll diagnose the issue and provide a lasting solution. Our trucks are stocked with common parts, allowing us to complete most furnace repairs in just one visit.

Boilers

Generally, boilers are durable systems. But even top-of-the-line systems can break down. Leaks, pressure loss, or inconsistent heating are all signs your boiler needs professional care. Allied technicians have decades of experience with hydronic systems, and we’ll restore the performance of yours.

Heat Pumps

Your heat pump works hard year-round, pulling double duty to heat in the winter and cool in the summer. If your heat pump struggles to switch modes, makes unusual noises, or fails to maintain the right temperature, it’s time to call in our experts. We handle compressor repairs, refrigerant leaks, and control system issues to keep your home comfortable.

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.
