Top 10 Questions Homeowners Ask About Their Heating System

November 5, 2025

When winter arrives, your heating system becomes one of the most important parts of your home. But when something goes wrong or you start thinking about upgrading, it can be hard to know where to start. At Cerrone Plumbing, Heating & Air Conditioning, we answer homeowner questions about heating systems every day.

Whether you have a furnace, boiler, or heat pump, understanding how your heating system works can help you make smarter, more energy-efficient decisions for your home. Here are answers to the top 10 questions we hear from homeowners.

  • 1. How do I know what kind of heating system I have?

    If your home has vents that blow warm air, you likely have a furnace heating system. If you see radiators or baseboards that get hot, that’s a boiler heating system. Homes with both heating and cooling from one unit typically use a heat pump system. Knowing what type you have helps you schedule the right maintenance and repairs.

  • 2. What size heating system do I need?

    Choosing the right-sized heating system is crucial for comfort and efficiency. A system that’s too small will constantly run, while one that’s too large will short cycle and waste energy. Cerrone’s HVAC professionals perform detailed load calculations to make sure your heating system fits your home perfectly.

  • 3. How long does a heating system last?

    Most furnaces last between 15-20 years, and boilers can often last a bit longer with regular maintenance. However, if your heating system is older, struggles to keep up, or needs frequent repairs, it may be time to consider an upgrade to a more efficient model.

  • 4. Should I repair or replace my heating system?

    If your heating system is more than 15 years old and your energy bills keep rising, replacement is often the smarter investment. New systems run more efficiently, saving you money over time. Cerrone’s team can help you weigh the costs of repair versus replacement to find the best solution for your home.

  • 5. How often should I schedule heating system maintenance?

    Experts recommend servicing your heating system once a year, ideally before cold weather hits. Regular tune-ups keep your equipment running efficiently, extend its lifespan, and help prevent unexpected breakdowns in the middle of winter.

  • 6. What temperature should I set my thermostat in winter?

    For most households, a comfortable winter thermostat setting is around 68°F to 70°F during the day and a few degrees lower at night. If you have a programmable or smart thermostat, you can schedule temperature changes to keep your home cozy and reduce energy costs when you’re away.

  • 7. Why are some rooms in my home colder than others?

    Uneven heating is a common sign your heating system may need attention. Dirty filters, blocked vents, leaky ducts, or an aging system can all cause inconsistent temperatures. Cerrone’s experienced technicians can inspect your system, balance airflow, and restore even comfort to every room.

  • 8. How can I make my heating system more efficient?

    A few small changes can make a big difference. Replace filters regularly, seal air leaks, and schedule professional maintenance each year. If your heating system is outdated, upgrading to a high-efficiency furnace or heat pump can significantly reduce your monthly energy bills.

  • 9. What’s the difference between a furnace and a boiler?

    A furnace heating system warms air and distributes it through ducts, while a boiler system heats water that travels through pipes to radiators or baseboards. Both can run on natural gas, propane, or oil—Cerrone’s HVAC experts can help you decide which is right for your home.

  • 10. How much does a new heating system cost?

    Costs vary depending on your home’s size, the system type, and energy efficiency rating. Cerrone provides upfront pricing, financing options, and personalized recommendations so you can invest in the best heating system for your budget and comfort.
