Common Home Heating Issues and How to Fix Them

When the temperatures drop in Westborough, Newton, or anywhere across Boston Metro West, a reliable heating system is a must. But even the best systems can run into trouble over time. If your home isn’t staying warm, it could be due to a minor issue—or a sign that your system needs professional attention.

At CPS Heating & Cooling, we help homeowners identify and resolve heating issues before they turn into major headaches. Below are some of the most common heating problems and what they might mean for your system.

1. Cold Air Coming from the Vents

If your furnace or heat pump is blowing cold air, the fix might be as simple as adjusting your thermostat or replacing a dirty filter. But it could also indicate a more serious problem, such as a faulty pilot light, a malfunctioning thermocouple, or issues with the blower motor.

2. Uneven Heating in Rooms

Hot and cold spots throughout your home could mean your system isn’t distributing heat properly. This might be due to leaky ductwork, poor insulation, or an aging unit struggling to keep up. CPS Heating & Cooling can help pinpoint the issue and recommend the right solution, whether it’s duct sealing or system upgrades.

3. Unusual Noises

Banging, rattling, or squealing sounds are never a good sign. They may point to loose parts, motor issues, or even a cracked heat exchanger. Don’t ignore these noises—schedule a professional inspection to avoid further damage.

4. Short Cycling

Short cycling is when your furnace turns on and off more frequently than normal. This can lead to higher energy bills and a shorter system lifespan. Causes might include an oversized system, a dirty flame sensor, or thermostat problems—all of which our trained technicians can assess and repair.

5. Sudden Increase in Energy Bills

If your heating bills spike without a clear reason, your system might be working harder than it should. Clogged filters, poor airflow, and outdated equipment can all reduce efficiency. Preventative maintenance from CPS Heating & Cooling can keep your system running smoothly and your costs in check.
