When buying a heating system for your home, make sure you get the right size.
According to Bryan Simning, owner of Valley Comfort Heating and Air in Santa Rosa, one of the biggest mistakes homeowners make when purchasing heating systems is oversizing them. “Most people think bigger is better, but that’s simply not true when it comes to heating systems,” he says. “If the system is too large for your home, it’s really no better than a bare furnace, even if it’s an energy-efficient model.”
The best way to ensure your heating system is the right size for your home is to have a professional HVAC technician provide a detailed estimate. Mr. Simning says it’s important to watch your technician as he’s giving the estimate and make sure he takes the time to do it right. “It takes about two hours to properly size a heating system, from doing the load calculations to studying the duct system to figuring out how to properly heat and cool specific rooms. If the technician tells you right away that he can replace your old system with something of a similar size, you should look for another company.”
Mr. Simning says it’s also important to inform your HVAC technician about various aspects of your lifestyle before deciding on a heating system. Does anyone in your home have respiratory problems like asthma or allergies? Do you have specific daily habits that necessitate the system being turned on or off at certain times? Are there any hot or cold spots in your house? These factors can have a big impact on the type and configuration of the heating system you choose.
When it comes to estimating energy savings, make sure you have a year’s worth of PG&E bills (covering both winter and summer) to show your HVAC technician. If your utility bill is relatively low (about $50 per month), a high-efficiency system won’t save you much money or greatly reduce your carbon footprint, so you’re probably better off with a less expensive and less efficient system. If you’re worried about the carbon footprint of a less efficient HVAC system, consider taking the money you save and applying it to reducing your energy usage somewhere else.
Additional Considerations When Choosing a Heating System for Your Home
Choosing the right heating system involves more than just size. There are several factors that homeowners often overlook, which can greatly impact the system’s efficiency, longevity, and overall performance. Here are additional aspects to consider before making a purchase:
1. Assess Your Home’s Insulation Quality
Even the most well-sized heating system may struggle to maintain optimal temperatures if your home isn’t well-insulated. Insulation in walls, ceilings, and floors significantly affects how well your home retains heat. Poor insulation can lead to heat loss, forcing your system to work harder and consume more energy. Have your insulation assessed before purchasing a new system, as improving it may reduce the load on your heating system and save on energy costs.
2. Evaluate Different Fuel Types and Costs
Heating systems are available in various fuel options, including natural gas, electric, propane, and oil. Each type has different costs, availability, and environmental impacts. In California, where natural gas is a popular and often cost-effective option, you might find this fuel source appealing. However, electric and geothermal options may be worth exploring for their lower emissions and increasing cost-efficiency. Consult with your HVAC technician to determine the best fuel source based on local rates, environmental impact, and your home’s specific requirements.
3. Consider Adding a Smart Thermostat for Energy Efficiency
Smart thermostats can optimize energy use by allowing you to set heating schedules, monitor energy consumption, and even control your heating remotely. Many models also learn your habits and adjust settings to maximize efficiency automatically. By pairing a smart thermostat with your heating system, you can reduce energy costs and enjoy more consistent comfort without manually adjusting the thermostat.
4. Factor in Maintenance Costs and Requirements
Different heating systems come with varying levels of maintenance needs and associated costs. For example, gas furnaces typically need annual inspections and filter replacements, while electric systems might require less frequent upkeep. Research the maintenance demands of your chosen system, and consider a maintenance plan with your HVAC provider to ensure it runs efficiently over the years. A well-maintained system not only lasts longer but also operates more efficiently, helping to keep utility bills in check.
5. Pay Attention to Air Quality Features
If air quality is a concern for your household, particularly for those with respiratory issues, look for heating systems that offer air purification features. Some systems include advanced filters or can be paired with add-ons like air scrubbers or UV lamps to reduce allergens, dust, and bacteria. Talk to your HVAC technician about options to improve air quality, especially if anyone in your home has allergies or asthma.
6. Check for Rebates and Incentives for Energy-Efficient Models
Many regions offer rebates and incentives for purchasing energy-efficient heating systems, which can help offset upfront costs. For instance, systems with ENERGY STAR ratings often qualify for these programs, providing savings on installation costs or even tax credits. Check with your local utility company or government websites to see what’s available in Santa Rosa and surrounding areas. These financial incentives can make investing in a more efficient system easier on your budget.
7. Prepare Your Ductwork for Optimal Heating
The condition of your ductwork plays a crucial role in how well your heating system distributes warmth throughout your home. Leaky or poorly insulated ducts can lead to heat loss, reducing system efficiency and creating inconsistent temperatures in different rooms. Ask your HVAC technician to inspect and, if needed, repair or insulate your ducts to ensure optimal airflow. Properly sealed ducts not only improve comfort but can also reduce energy costs by preventing warm air from escaping.
By taking these factors into account, you’ll be better equipped to choose a heating system that meets your household’s unique needs. Consulting a knowledgeable HVAC technician who can assess your home and lifestyle thoroughly is key to finding a solution that balances comfort, efficiency, and cost-effectiveness.
