We Install Furnaces for Long-Term Performance.
Furnace installation and replacement done right. MightyServ installs safe, properly sized systems designed for consistent, reliable heat and long-term performance.
Southern California is perceived to be warm and sunny all year long. While we’re fortunate to enjoy minimal precipitation and nice temperatures, the weather can dip into the 30s or 40s on a cold winter day. On those chilly days, we notice that most homeowners look to their heater to keep their home a cozy 70 degrees. A reliable heater makes all the difference in your comfort over the winter. That’s why we here at MightyServ provide high-quality furnace installation services.
What to Expect From A MightyServ Furnace Installation
The quality of your furnace installation directly impacts comfort, efficiency, and how well your system performs over time. Our process is designed to get every detail right from the start so you can feel confident in your investment.
✓ Careful home evaluation. Every installation begins with a thorough assessment of your home. We review square footage, insulation, airflow, and existing ductwork to determine the proper furnace size and performance level. Correct sizing helps prevent uneven heating, efficiency loss, and unnecessary strain on the system.
✓ System recommendations you can trust. After the evaluation, we help you select a furnace that aligns with your comfort needs, efficiency goals, and budget. Our focus is on long-term reliability — not recommending equipment you don’t need.
✓ Professional installation. Our technicians install your furnace according to local codes and manufacturer specifications, paying close attention to safety, airflow, and overall system performance. Precision during installation helps protect your investment and supports dependable operation.
✓ Performance testing and final checks. Before the job is complete, we fully test the system, calibrate key components, and confirm everything is working properly. We also walk you through your new equipment so you know what to expect from day one.
✓ Built for long-term reliability. A properly installed furnace should deliver consistent comfort for years. Our structured approach minimizes the risk of future issues and helps ensure your system performs the way it was designed to.

Some L.A. homes operate heat pumps or ductless systems. But, since gas is often cheaper than electricity, many Los Angeles homes use furnaces. If your home runs on a furnace, here are some things to think about.
How Do You Know When It’s Time to Replace Your Furnace:
- DOES YOUR CURRENT FURNACE WORK THE WAY IT SHOULD?
Ultimately, your furnace should make you comfortable in a reliable way. If your furnace emits odors, makes loud noises, heats your home unevenly, or requires extra effort to operate, we can help. Repairs may solve your problem. But, you may need to replace your system. Our qualified technicians can discern between the two. - HOW OLD IS YOUR FURNACE?
If your furnace is under 10 years old, it’s very likely better to repair it. A well-maintained and newly repaired furnace of this age should live 8-10 more years and by then, newer technologies will have emerged. If your furnace is 11-20 years old, it could be a candidate for replacement. - WHEN DID YOU LAST HAVE YOUR FURNACE PROFESSIONALLY SERVICED?
If your furnace hasn’t been given consistent attention and maintenance, start there first. One of our technicians will come out to your home, assess the health of the machine, and make further recommendations. Many minor issues are fixable and once you get on a consistent maintenance plan, it’s easier to avoid big repair costs.If you have your furnace serviced yearly and you’re still in need of repairs, it might be time to consider how repair costs are adding up. Repairs can cost 50% of the cost of a new system or more. At some point, a new furnace installation will pay for itself in reduced repairs and headaches alone.
- ARE YOUR HEATING BILLS INCREASING IN AN UNUSUAL WAY?
The efficiency of a furnace is measured by its AFUE percentage. AFUE stands for Annual Fuel Utilization Efficiency. Older systems could have energy efficiency (AFUE) ratings as low as 78%. A rating of 80-85% is a standard for the industry and some systems today are as high as 97%. If your system has a low AFUErating, it may be worth replacing. Your new system could start saving you money immediately after installation.
These considerations will help you determine whether it’s time to replace your system. If you’re ready to replace your furnace, we can help!
FAQs
How long does furnace installation take?
Most furnace installations can be completed in a single day. More complex projects — such as ductwork modifications or system upgrades — may take longer, but we’ll explain the timeline before work begins.
What size furnace does my home need?
Proper sizing is critical. A furnace that’s too large or too small can reduce efficiency and shorten system lifespan. We evaluate your home’s square footage, insulation, airflow, and layout to recommend the right system.
How do I know if it’s time to replace my furnace?
If your furnace is 10 years old, needs frequent repairs, struggles to heat evenly, or causes rising energy bills, replacement is often the smarter long-term investment. A new system can improve comfort, efficiency, and reliability.
Will a new furnace lower my energy bills?
In many cases, yes. Modern high-efficiency furnaces use less energy to produce consistent heat, which can help reduce monthly utility costs while improving overall comfort.
Should I repair my furnace or replace it?
If repair costs are adding up or your system is nearing the end of its service life, replacement may provide better long-term value. We walk you through both options so you can make a confident decision.
Do you install high-efficiency furnaces?
Yes. We install high-efficiency systems designed for dependable heating, improved airflow, and long-term performance.
Can you replace my furnace before it completely fails?
Absolutely — and many homeowners choose to do so. Proactive replacement helps you avoid unexpected breakdowns, emergency installation, and periods without heat.
