What Furnace Installation Involves and When It Makes Sense

Furnace Installation is the removal of your old furnace and the setup of a new one, matched to your home's heating needs, your ductwork and your gas and venting. It makes sense when your furnace is near the end of its working life, when repairs are coming more often, or when a major part fails and fixing it would cost a large share of a new system.
A furnace replacement is one of the bigger decisions a homeowner makes, and it deserves more than a sales pitch. In Loveland, a furnace may carry the house through months of cold nights and big temperature swings, so the right size and a careful setup matter more than the brand name on the cabinet. We start by understanding your home, explain the options in plain terms and let you decide on your own timeline.

Signs It's Time to Replace Your Furnace
Not every old furnace needs to go, and not every breakdown means replacement. These are the signs that tip the balance:
- The furnace is roughly 15 years old or more and starting to need regular repairs
- A single repair would cost a large share of what a new furnace costs
- Heating bills keep climbing even though your habits haven't changed
- Some rooms never get warm, or the furnace runs constantly on cold nights to keep up
- A cracked heat exchanger, heavy rust or a failed major component
- You're adding on, finishing a basement or planning to add central air conditioning
If your furnace is younger and the problem is a single part, Furnace Repair is usually the better call, and your technician will tell you so.

Choosing the Right Furnace for Your Home
Furnaces differ in a few ways that matter more than the label. Here's what we walk through with you.
Size
Bigger isn't better. An oversized furnace heats the house in short bursts, shuts off, then starts again, which wears parts, wastes fuel and leaves rooms uneven. An undersized one runs nonstop on the coldest nights. We calculate your home's heating load from its square footage, insulation, windows and layout instead of copying the old furnace's size, since the old one may never have been sized right.
Efficiency
Standard-efficiency furnaces vent hot exhaust up a metal flue. High-efficiency condensing furnaces pull more heat out of the same gas, then vent cooler exhaust through plastic pipes and drain the water they produce. They cost more up front and use less gas each winter. ENERGY STAR explains what separates certified high-efficiency furnaces from standard models.
Comfort features
Single-stage furnaces run at full output every time. Two-stage and modulating furnaces run at lower output most of the time, which means quieter operation, steadier temperatures and fewer drafts. A variable-speed blower adds smoother airflow and pairs well with whole-home air cleaning.
Pairing with a heat pump
Some homeowners pair a high-efficiency furnace with a heat pump in a dual-fuel setup. The heat pump handles mild days and the furnace takes over in deep cold. It's worth a conversation if you're replacing your air conditioning soon too.

Frequently asked questions
Have questions? We've got answers. Browse the frequently asked questions below to learn more about our heating services, what to expect during your appointment, and how Fix-it 24/7 can help keep your home warm, comfortable, and running efficiently all season long.
Yes. Air is thinner at elevation, so a gas furnace burns differently than it would at sea level. Manufacturers publish high-altitude instructions that may call for gas pressure adjustments or different burner orifices. Following them helps the furnace burn cleanly, run efficiently and protect the heat exchanger over time. Every Furnace Installation we do is set up and tested to the manufacturer's high-altitude specifications for your home's elevation.
Yes. Replacing a furnace typically requires a mechanical permit, and the work gets a final check from the building department once it's done. Fix-it 24/7 pulls the permit as part of Furnace Installation and coordinates that final check, so you don't have to deal with the paperwork. A permitted install also keeps clean records on the work, which can matter when you sell your home or file an insurance claim.
Yes, Fix-it 24/7 handles complete removal and proper disposal of your old furnace as part of our installation service. We ensure all components are disposed of in accordance with local environmental regulations, and we'll leave your installation area clean and tidy.
Many gas furnaces last roughly 15 to 20 years, though the range is wide. Sizing, installation quality and how well the furnace is cleaned and maintained make a bigger difference than the brand. Furnaces that run long hours through cold, dry winters see a lot of wear, and dust buildup on the blower wheel and burners adds strain. A yearly Furnace Deep Clean and Tune-Up helps a furnace reach the long end of that range, though no maintenance stops every part from eventually wearing out.
Most furnace installations can be completed in a single day, typically taking 4-8 hours depending on the complexity of your system and any necessary ductwork modifications. Our technicians work efficiently to minimize disruption to your daily routine while ensuring proper installation.
For most Northern Colorado homes, a high-efficiency condensing furnace is worth a close look because the heating season is long and the furnace runs a lot of hours. It uses less gas to make the same heat, which adds up winter after winter. It also needs plastic venting and a condensate drain, which can add installation work in some homes. Your Furnace Installation estimate will show the standard and high-efficiency options side by side so you can compare.
The right size comes from a heating load calculation, not from the square footage alone or the size of your old furnace. The calculation looks at your home's insulation, windows, layout, air leaks and local climate. An oversized furnace short cycles, wastes gas and heats unevenly, while an undersized one runs nonstop on the coldest nights. During a Furnace Installation visit, your technician works out the load and explains the size they recommend and why.
New furnaces come with manufacturer warranties that typically cover parts for 5-10 years, depending on the model and brand. Fix-it 24/7 also provides warranties on our installation workmanship. We'll explain all warranty coverage and help you register your new furnace with the manufacturer.
Fall is typically the ideal time for furnace installation, allowing you to address any heating issues before Denver's cold winter weather arrives. However, Fix-it 24/7 provides installation services year-round, including emergency replacement when your current system fails unexpectedly.
