Buying a new heating and cooling system is one of the biggest home improvement investments a Clearfield homeowner will make. It is not something you should decide under pressure during a breakdown, and it is not something you should leave entirely up to a salesman who earns a commission on the most expensive option.
This guide breaks down what actually matters when replacing your HVAC system — sizing, efficiency, equipment choices, and timing — so you can make an informed decision on your terms.
When Replacement Actually Makes Sense
Not every failing system needs to be replaced. But some do, and here is how to tell the difference.
The system is 15 years or older and repair costs are increasing. The average residential furnace lasts 15 to 20 years. Central air conditioners last 12 to 17 years. If your equipment is in that range and you have spent several hundred dollars or more on repairs in the past two years, every additional repair is money that would be better invested in new equipment. We covered the repair-versus-replace decision for furnaces in more detail on our heating page — the same logic applies to AC systems.
The system uses R-22 refrigerant. R-22 was phased out of production under the EPA’s Clean Air Act regulations. If your air conditioner or heat pump still uses R-22, getting a recharge is expensive and increasingly difficult. Replacing the system with one that uses R-410A or the newer R-454B is the only practical long-term solution.
Your energy bills have climbed steadily. If your gas and electric bills have gone up over the past few years without a change in your usage habits, declining system efficiency is likely the cause. Older furnaces operate at 78 to 85 percent AFUE. Modern high-efficiency models run at 95 to 98 percent. Older AC units might have a SEER rating of 10 to 13. Current models start at 14 SEER and high-efficiency units reach 20 or higher. The difference shows up on every monthly bill.
Comfort problems that repairs have not solved. If some rooms are always too hot, others are always too cold, and the system runs constantly without ever satisfying the thermostat, the problem may not be the furnace or AC at all — it may be a system that was undersized or poorly installed from the beginning. In that case, repairs are treating symptoms instead of fixing the actual issue. A properly designed replacement solves the root problem.
What Matters Most in a New HVAC System
When you start getting quotes, here is what to pay attention to — and what to ignore.
Proper sizing based on a Manual J load calculation. This is the single most important factor in a new HVAC installation. A load calculation accounts for your home’s square footage, ceiling height, insulation, window area, orientation, and local climate data. A system that is too small will run constantly and never keep up. A system that is too large will short cycle, waste energy, and create uneven temperatures throughout the house. Any contractor who sizes your system by looking at the old equipment and ordering the same thing is skipping the most critical step.
Efficiency ratings that match your budget and payback timeline. A 98 percent AFUE furnace saves more on gas than a 95 percent model, but it also costs more upfront. For most Clearfield homeowners, a 95 or 96 percent AFUE furnace paired with a 16 to 18 SEER air conditioner hits the sweet spot between performance and return on investment. Going higher makes sense in large homes with high utility bills. Going with the cheapest option makes sense for no one — the energy penalty over 15 years costs more than the price difference.
Ductwork condition. Putting a new high-efficiency system on old, leaky ductwork is like putting a new engine in a car with bald tires. The system cannot deliver its rated performance if the ducts are losing air along the way. A good installer evaluates your ductwork as part of the replacement process and recommends sealing or repairs where needed.
Warranty coverage. Equipment warranties vary by brand and by installer. Most manufacturers require professional installation by a certified dealer for the full warranty to apply. That matters because a warranty claim on a system installed by an uncertified contractor will be denied. As a Coleman installer and authorized Daikin dealer, Wasatch Front Heating & Cooling meets the installation requirements for both brands, which means your warranty is protected from day one.
Equipment Options We Install in Clearfield
We are not locked into one brand. We install equipment based on what fits your home, your budget, and your long-term goals.
Coleman gas furnaces and air conditioners. Coleman makes reliable, well-built equipment that performs well in cold climates. Their mid-range and high-efficiency models are popular with Clearfield homeowners who want quality without paying for the premium brand name markup.
Daikin ductless mini split systems. For homes without ductwork, room additions, or homeowners who want zone-by-zone control, Daikin mini splits provide both heating and cooling at high efficiency. We are an authorized Daikin mini split dealer with factory training on their full line.
Matched systems. A furnace and air conditioner are designed to work as a pair. Mixing an old furnace with a new AC — or vice versa — reduces efficiency and can void warranty coverage. When we replace a system, we make sure all components are matched and rated to work together.
The Best Time to Replace Your HVAC System in Clearfield
Spring and early fall are the ideal windows. Demand for installations is lower, scheduling is easier, and you avoid the rush pricing that sometimes appears during extreme weather. Replacing in April or May means your new AC is ready before summer. Replacing in September or October means your new furnace is tested and running before the first freeze.
If your system fails mid-season, we handle emergency replacements as well — but if you have any sense that your system is nearing the end of its life, planning ahead gives you more options and less stress.

Frequently Asked Questions
How long does a full HVAC replacement take in Clearfield?
A standard furnace and AC replacement in a Clearfield home with existing ductwork typically takes one day. If ductwork modifications are needed, it may extend into a second day. We will give you a clear timeline before the work begins.
Is financing available for HVAC replacement?
Many homeowners finance new HVAC systems. Ask us about current financing options when we provide your estimate. We will walk you through the monthly payment scenarios so you can see exactly what the investment looks like over time.
What happens to my old equipment when you install a new system?
We remove and haul away the old equipment as part of the installation. We handle proper disposal, including reclaiming any refrigerant from the old AC system as required by EPA regulations. You do not need to do anything with the old unit.
