Common Furnace Installation Mistakes Denver Homeowners Make (And How to Avoid Them)

Denver winters are no joke. When your furnace gives out, getting a new one installed quickly and correctly is paramount. However, rushing into a replacement or making uninformed decisions can lead to long-term problems. As a local HVAC company, we’ve seen our share of furnace installation mishaps. Here are some of the most common mistakes Denver homeowners make and how you can avoid them.

Mistake 1: Choosing the Wrong Size Furnace

One of the biggest errors is installing a furnace that’s either too large or too small for your home. Many homeowners assume bigger is always better, but that's not the case with furnaces.

• Too large: A furnace that's too powerful will heat your home too quickly, then shut off. This 'short-cycling' wastes energy, creates uneven heating, and puts undue stress on components, leading to premature wear and tear. It also doesn't run long enough to properly dehumidify your home, which can be a comfort issue.
• Too small: An undersized furnace will struggle to keep your home warm, especially during Denver's coldest stretches. It will run constantly, leading to higher energy bills and still potentially failing to reach your desired temperature.

The Better Move: A professional HVAC technician will perform a Manual J load calculation. This complex calculation considers your home's square footage, insulation levels, window types, local climate data (hello, Denver blizzards!), and even your home's orientation to determine the precise heating capacity needed. Don't let anyone skip this crucial step.

Mistake 2: Overlooking Ductwork Inspection and Repair

Your furnace is only as good as the ductwork distributing the air. Many homeowners focus solely on the new furnace unit itself and neglect to have their existing ductwork thoroughly inspected.

• Leaky ducts: Even a new, highly efficient furnace will struggle if heated air is escaping through cracks and gaps in your ducts before it reaches your living spaces. This is a common energy drain.
• Poorly sized ducts: Older homes, or those that have had additions, might have ductwork that isn't appropriately sized for a new, more powerful or efficient furnace, leading to airflow issues and reduced performance.

The Better Move: Before installation, ensure your chosen HVAC provider includes a comprehensive ductwork inspection. They should identify and seal any leaks, and advise if duct modifications or replacements are necessary to optimize your new furnace's performance.

Mistake 3: Prioritizing Lowest Price Over Value and Expertise

It's natural to want a good deal, especially on a major investment like a new furnace. However, choosing a contractor solely based on the lowest bid can often lead to more expensive problems down the road.

• Subpar installation: An inexperienced or rushed installer might cut corners, leading to safety hazards, inefficient operation, and frequent breakdowns.
• Lack of proper permits: In Denver, furnace installations often require permits and inspections to ensure they meet local building codes. A low-bid contractor might skip these, leaving you with an unapproved and potentially unsafe system.
• Poor warranty support: If something goes wrong, a company focused only on low prices might not be around to honor their work or the manufacturer's warranty.

The Better Move: Look for a reputable, licensed, and insured HVAC company with a strong local track record. Get multiple quotes, but compare them based on the scope of work, the specific furnace model, included warranties, and the installer's reputation. Ask about their permitting process and ensure they stand behind their work.

Mistake 4: Ignoring Modern Efficiency and Smart Features

When replacing an older furnace, some homeowners opt for a basic model without considering the long-term benefits of modern technology.

• Sticking with low efficiency: Older furnaces might have AFUE (Annual Fuel Utilization Efficiency) ratings in the 60s or 70s. Modern furnaces can reach 90% AFUE or higher, meaning significantly lower energy bills over the unit's lifespan.
• Skipping smart thermostats: A basic thermostat won't unlock the full potential of a new, high-efficiency furnace. Smart thermostats allow for precise scheduling, remote control, and even learning capabilities that optimize energy use.

The Better Move: Discuss high-efficiency options with your technician. While the upfront cost might be slightly higher, the energy savings over the life of the unit, combined with potential rebates, often make them a more economical choice in the long run. Also, consider pairing your new furnace with a smart thermostat for maximum comfort and savings.

Replacing your furnace is a significant home improvement. By avoiding these common pitfalls and partnering with a knowledgeable local professional, you can ensure your Denver home stays warm and comfortable for many winters to come.
