Before the Big Day: Preparing for Your New Furnace

This section covers the essential steps and decisions homeowners must make before the installation team arrives, ensuring a smooth and successful upgrade.

Telltale Signs Your Furnace Needs Replacing

Knowing when to replace your furnace can save you from an emergency breakdown and a major headache. There are several clear indicators that your heating system is nearing the end of its life.

Age is the biggest clue. Most natural gas furnaces last 15 to 20 years, while electric units can last up to 30 years. If your system is in or past this age range, it's time to start planning for a replacement.

Beyond age, watch for these warning signs:

  • Frequent repair calls: If you're constantly calling an HVAC technician, those bills add up. It's often more economical to invest in a complete furnace installation than to continue with costly repairs.
  • Rising energy bills: An aging furnace works harder to maintain temperatures, consuming more energy. This is one of The Top Signs Your Furnace Needs Maintenance.
  • Uneven heating: If some rooms are hot while others are cold, your furnace may be losing its ability to distribute heat effectively.
  • Strange noises: Banging, rattling, or screeching sounds often signal serious mechanical issues that need immediate attention, as detailed in our guide on Heating System Problems to Look Out For This Winter.
  • Visual clues: Soot around vents or rust on the unit can indicate dangerous combustion problems. For gas furnaces, the flame should be blue; a yellow or flickering flame could mean a carbon monoxide risk.

Recognizing these signs early gives you time to plan and budget for a replacement before you're left in the cold.

Choosing Your New Furnace: Types, Efficiency, and Sizing

Selecting the right furnace is a major decision that will impact your comfort and energy bills for years. Here's a breakdown of your options for a complete furnace installation.

Natural gas furnaces are a popular choice, offering lower operating costs and efficiency ratings (AFUE) between 80% and 98%. They typically last 15-20 years.

Electric furnaces can reach 100% efficiency, but higher electricity costs can make them more expensive to run. They have a longer lifespan of up to 30 years and are ideal for homes without gas access.

Heat pumps are excellent for our mild San Diego County climate, providing both heating and cooling in one efficient system. They generally last 10-15 years.

Furnace TypeEfficiency Rating (Typical)Operating Cost (General)Lifespan (Average)Best Suited For
Natural Gas80-98% AFUEOften lower15-20 yearsHomes with natural gas access; Colder climates
ElectricUp to 100% AFUEOften higherUp to 30 yearsHomes without gas access; Milder climates
Heat PumpHigh SEER/HSPFEfficient, but can need supplemental heat in extreme cold10-15 years (similar to AC)Milder climates, where both heating and cooling are needed from one unit

Understanding efficiency ratings is key. A 95% AFUE furnace converts nearly all its fuel to heat, while an older 80% unit wastes 20% of it. High-efficiency models cost more upfront but can significantly reduce your monthly bills. This helpful furnace buying guide offers more insights.

Proper sizing is critical. An undersized furnace runs constantly and wears out fast, while an oversized unit short-cycles, wasting energy. A professional BTU calculation considers your home's size, age, insulation quality, window efficiency, and local climate conditions. The state of your ductwork is also a major factor.

We perform a thorough in-home assessment for every complete furnace installation to ensure your new system is perfectly matched to your home's needs, as part of our HVAC Installation Services in Escondido, CA.

Before the Big Day: Preparing for Your New Furnace

This section covers the essential steps and decisions homeowners must make before the installation team arrives, ensuring a smooth and successful upgrade.

Telltale Signs Your Furnace Needs Replacing

Knowing when to replace your furnace can save you from an emergency breakdown and a major headache. There are several clear indicators that your heating system is nearing the end of its life.

Age is the biggest clue. Most natural gas furnaces last 15 to 20 years, while electric units can last up to 30 years. If your system is in or past this age range, it's time to start planning for a replacement.

Beyond age, watch for these warning signs:

  • Frequent repair calls: If you're constantly calling an HVAC technician, those bills add up. It's often more economical to invest in a complete furnace installation than to continue with costly repairs.
  • Rising energy bills: An aging furnace works harder to maintain temperatures, consuming more energy. This is one of The Top Signs Your Furnace Needs Maintenance.
  • Uneven heating: If some rooms are hot while others are cold, your furnace may be losing its ability to distribute heat effectively.
  • Strange noises: Banging, rattling, or screeching sounds often signal serious mechanical issues that need immediate attention, as detailed in our guide on Heating System Problems to Look Out For This Winter.
  • Visual clues: Soot around vents or rust on the unit can indicate dangerous combustion problems. For gas furnaces, the flame should be blue; a yellow or flickering flame could mean a carbon monoxide risk.

Recognizing these signs early gives you time to plan and budget for a replacement before you're left in the cold.

Choosing Your New Furnace: Types, Efficiency, and Sizing

Selecting the right furnace is a major decision that will impact your comfort and energy bills for years. Here's a breakdown of your options for a complete furnace installation.

Natural gas furnaces are a popular choice, offering lower operating costs and efficiency ratings (AFUE) between 80% and 98%. They typically last 15-20 years.

Electric furnaces can reach 100% efficiency, but higher electricity costs can make them more expensive to run. They have a longer lifespan of up to 30 years and are ideal for homes without gas access.

Heat pumps are excellent for our mild San Diego County climate, providing both heating and cooling in one efficient system. They generally last 10-15 years.

Furnace TypeEfficiency Rating (Typical)Operating Cost (General)Lifespan (Average)Best Suited For
Natural Gas80-98% AFUEOften lower15-20 yearsHomes with natural gas access; Colder climates
ElectricUp to 100% AFUEOften higherUp to 30 yearsHomes without gas access; Milder climates
Heat PumpHigh SEER/HSPFEfficient, but can need supplemental heat in extreme cold10-15 years (similar to AC)Milder climates, where both heating and cooling are needed from one unit

Understanding efficiency ratings is key. A 95% AFUE furnace converts nearly all its fuel to heat, while an older 80% unit wastes 20% of it. High-efficiency models cost more upfront but can significantly reduce your monthly bills. This helpful furnace buying guide offers more insights.

Proper sizing is critical. An undersized furnace runs constantly and wears out fast, while an oversized unit short-cycles, wasting energy. A professional BTU calculation considers your home's size, age, insulation quality, window efficiency, and local climate conditions. The state of your ductwork is also a major factor.

We perform a thorough in-home assessment for every complete furnace installation to ensure your new system is perfectly matched to your home's needs, as part of our HVAC Installation Services in Escondido, CA.

Preparing Your Home for the Installation Appointment

Once you've scheduled your complete furnace installation, a few simple preparations will help our technicians work safely and efficiently.

Create a clear workspace. Our team needs room to work. Please clear at least three feet of space around your existing furnace, moving any boxes, equipment, or other stored items.

Secure your pets for their safety and to allow our team to focus on the technical work. It's also helpful to inform household members about the installation to manage expectations regarding noise or temporary utility interruptions.

Ensure a clear access path from our truck to the furnace location. We need to carry out the old unit and bring in the new one, so hallways and stairs should be unobstructed.

Our technicians will need access to utility connections, including the main gas shut-off valve, electrical panel, and water shut-off. Please ensure these are easily accessible.

We inspect ductwork during our initial consultation. If we find any issues that could impact your new furnace's performance, we will discuss repair or replacement options with you.

The cost of a complete furnace installation varies, as every home is unique. Key factors influencing the price include:

  • Furnace type: Gas, electric, and heat pump systems have different price points.
  • Efficiency ratings: Higher AFUE ratings cost more upfront but provide greater long-term energy savings.
  • Size and requirements: Your home's size and heating needs determine the required BTU capacity.
  • Brand and features: Options like variable-speed blowers affect the final price.
  • Labor complexity: The need for ductwork modifications, electrical upgrades, or new venting adds to the project scope.

We provide free, no-obligation quotes after a thorough in-home assessment to give you accurate pricing based on your specific needs, with no hidden surprises.

Is it cheaper to replace my furnace and air conditioner together?

In most cases, yes, replacing both units at the same time often saves money. The primary reason is shared labor costs, as many installation steps for the furnace and air conditioner overlap. This eliminates duplicated effort and reduces the overall cost.

Another major benefit is system compatibility. Modern HVAC systems are designed to work as matched pairs. A new high-efficiency furnace and air conditioner working together will operate at peak performance, delivering better comfort and lower energy bills than mismatched equipment. This also offers the convenience of a single installation project and a unified warranty period.

Why Complete Furnace Installation Matters for Your Home

A complete furnace installation means replacing your entire heating system with a new, energy-efficient unit that is professionally sized and installed for optimal performance and safety.

Key Components of Complete Furnace Installation:

  • Assessment & Sizing: Professional load calculation to determine correct BTU requirements.
  • Safe Removal: Proper disconnection and disposal of old equipment.
  • New Unit Installation: Setting the unit, connecting gas lines, electrical, and ductwork.
  • System Testing: Leak checks, airflow verification, and safety control testing.
  • Thermostat Integration: Connecting and calibrating temperature controls.

Homeowners typically need this upgrade when a furnace is 15-20 years old or breaks down frequently. A new installation takes 4-10 hours and can dramatically improve home comfort and energy efficiency. Modern gas furnaces can reach 95% efficiency or higher, a significant improvement over older 80% units, meaning more of your energy dollars heat your home.

Professional installation is crucial for safe operation, maintaining manufacturer warranty coverage, and ensuring consistent heat while meeting all local building codes. The investment pays dividends through lower energy bills, improved comfort, and reliable heating for years to come.

Before the Big Day: Preparing for Your New Furnace

This section covers the essential steps and decisions homeowners must make before the installation team arrives, ensuring a smooth and successful upgrade.

Telltale Signs Your Furnace Needs Replacing

Knowing when to replace your furnace can save you from an emergency breakdown and a major headache. There are several clear indicators that your heating system is nearing the end of its life.

Age is the biggest clue. Most natural gas furnaces last 15 to 20 years, while electric units can last up to 30 years. If your system is in or past this age range, it's time to start planning for a replacement.

Beyond age, watch for these warning signs:

  • Frequent repair calls: If you're constantly calling an HVAC technician, those bills add up. It's often more economical to invest in a complete furnace installation than to continue with costly repairs.
  • Rising energy bills: An aging furnace works harder to maintain temperatures, consuming more energy. This is one of The Top Signs Your Furnace Needs Maintenance.
  • Uneven heating: If some rooms are hot while others are cold, your furnace may be losing its ability to distribute heat effectively.
  • Strange noises: Banging, rattling, or screeching sounds often signal serious mechanical issues that need immediate attention, as detailed in our guide on Heating System Problems to Look Out For This Winter.
  • Visual clues: Soot around vents or rust on the unit can indicate dangerous combustion problems. For gas furnaces, the flame should be blue; a yellow or flickering flame could mean a carbon monoxide risk.

Recognizing these signs early gives you time to plan and budget for a replacement before you're left in the cold.

Choosing Your New Furnace: Types, Efficiency, and Sizing

Selecting the right furnace is a major decision that will impact your comfort and energy bills for years. Here's a breakdown of your options for a complete furnace installation.

Natural gas furnaces are a popular choice, offering lower operating costs and efficiency ratings (AFUE) between 80% and 98%. They typically last 15-20 years.

Electric furnaces can reach 100% efficiency, but higher electricity costs can make them more expensive to run. They have a longer lifespan of up to 30 years and are ideal for homes without gas access.

Heat pumps are excellent for our mild San Diego County climate, providing both heating and cooling in one efficient system. They generally last 10-15 years.

Furnace TypeEfficiency Rating (Typical)Operating Cost (General)Lifespan (Average)Best Suited For
Natural Gas80-98% AFUEOften lower15-20 yearsHomes with natural gas access; Colder climates
ElectricUp to 100% AFUEOften higherUp to 30 yearsHomes without gas access; Milder climates
Heat PumpHigh SEER/HSPFEfficient, but can need supplemental heat in extreme cold10-15 years (similar to AC)Milder climates, where both heating and cooling are needed from one unit

Understanding efficiency ratings is key. A 95% AFUE furnace converts nearly all its fuel to heat, while an older 80% unit wastes 20% of it. High-efficiency models cost more upfront but can significantly reduce your monthly bills. This helpful furnace buying guide offers more insights.

Proper sizing is critical. An undersized furnace runs constantly and wears out fast, while an oversized unit short-cycles, wasting energy. A professional BTU calculation considers your home's size, age, insulation quality, window efficiency, and local climate conditions. The state of your ductwork is also a major factor.

We perform a thorough in-home assessment for every complete furnace installation to ensure your new system is perfectly matched to your home's needs, as part of our HVAC Installation Services in Escondido, CA.

Preparing Your Home for the Installation Appointment

Once you've scheduled your complete furnace installation, a few simple preparations will help our technicians work safely and efficiently.

Create a clear workspace. Our team needs room to work. Please clear at least three feet of space around your existing furnace, moving any boxes, equipment, or other stored items.

Secure your pets for their safety and to allow our team to focus on the technical work. It's also helpful to inform household members about the installation to manage expectations regarding noise or temporary utility interruptions.

Ensure a clear access path from our truck to the furnace location. We need to carry out the old unit and bring in the new one, so hallways and stairs should be unobstructed.

Our technicians will need access to utility connections, including the main gas shut-off valve, electrical panel, and water shut-off. Please ensure these are easily accessible.

We inspect ductwork during our initial consultation. If we find any issues that could impact your new furnace's performance, we will discuss repair or replacement options with you.

The Complete Furnace Installation Process: A Professional's Walkthrough

When you choose Aelott Air Conditioning for your complete furnace installation, you're getting six decades of expertise. Here’s what to expect during our professional installation process.

Step 1: Consultation and Safe Removal of the Old Unit

Your complete furnace installation begins with an in-home assessment from one of our Energy Management Consultants. We perform a detailed load calculation to determine the precise BTU requirements for your home, considering factors like insulation, window quality, and your family's comfort preferences. We'll discuss system selection options and your budget in plain English.

On installation day, our certified technicians begin by shutting off gas and electricity to the old furnace, following strict safety protocols. We then carefully disconnect ductwork, gas lines, electrical connections, and exhaust venting.

We ensure the environmentally safe disposal of your old furnace, including proper recycling and handling of any hazardous materials. It's the right thing to do for our community.

Step 2: New Furnace Placement and Connections

Setting the new unit is a precise task. We ensure level placement, sometimes angling it slightly for proper condensate drainage, to prevent future issues.

Connecting ductwork requires creating tight seals at every joint to prevent air leaks that reduce efficiency and comfort. For gas furnaces, licensed professionals handle the gas line connection, testing every joint to detect even the smallest leaks.

Electrical wiring is done according to manufacturer specifications and local codes to ensure safe, reliable performance. For modern high-efficiency furnaces, condensate drain installation is essential to channel water safely away from the unit.

Proper venting (intake/exhaust), typically with new PVC piping, is critical for safety and efficiency. We ensure all sealing joints are perfect throughout the system.

You can learn more about the protocols we follow on our page about Key safety considerations for a complete furnace installation.

Step 3: Thermostat Integration and System Testing

The final phase brings everything together. Connecting the thermostat ensures proper communication between your controls and the new furnace. If you're upgrading to a smart thermostat, we'll handle the setup and show you how to use it.

During system startup, we carefully monitor the ignition sequence, blower operation, and overall performance. We then perform another round of checking for gas leaks with sensitive detection equipment.

Verifying airflow and checking the temperature rise (the difference between intake and output air temperature) tells us if the system is performing to manufacturer specifications. We conduct safety control tests on all protective features, like limit switches and flame sensors, to ensure they are working perfectly.

Finally, we calibrate the system by fine-tuning settings for optimal performance in your home. We'll walk you through your new system's operation, answer your questions, and provide all warranty documentation before we leave.

This meticulous process ensures your new complete furnace installation delivers the comfort and reliability you deserve. Learn how to get the most from your new system with our guide on How to Run Your Furnace Efficiently.

After the Installation: Maximizing Your Investment

Your new complete furnace installation is finished, but getting the most from your investment requires some ongoing care. These simple steps will ensure your system runs efficiently for years.

Essential Maintenance for a Long-Lasting Furnace

Your new furnace will perform best with regular attention. These simple tasks can extend its life and keep energy bills low.

  • Regular filter changes: This is the most important task you can perform. A dirty filter restricts airflow, forcing the system to work harder. Check your filter monthly and replace it every 1-3 months, or more often if you have pets or allergies.
  • Keep vents clear: Ensure furniture, rugs, or curtains are not blocking supply and return vents to allow for even heat distribution.
  • Annual professional tune-ups: Schedule a professional inspection each fall. Our technicians clean internal components, check connections, inspect gas lines, and test safety controls. This preventative maintenance catches small issues before they become expensive problems and is often required to maintain your warranty. During the visit, we'll also inspect your blower and check your ignition system for safe, reliable operation.

Understanding Warranties and Government Incentives

Your new furnace comes with valuable protections and potential savings. Manufacturer warranties typically cover parts for 5-10 years, but you must register your product with the manufacturer shortly after installation to activate full coverage. We will help you with this process.

At Aelott Air Conditioning, we also provide a labor warranty and a 100% satisfaction guarantee, so you can have complete confidence in your complete furnace installation.

Government rebates and incentives from federal, state, and local programs can significantly reduce your upfront cost. A great place to start is the Information on energy efficiency rebates website. Our team can also help identify local rebates in San Diego County. For more information, visit our page on Heating Installation Services in Escondido, CA.

The Benefits of a Professional vs. DIY Installation

While DIY projects can be appealing, furnace installation is a job best left to professionals. The risks of DIY work are serious and far outweigh any potential savings.

Safety is the biggest concern. Furnaces involve natural gas, high-voltage electricity, and carbon monoxide. A single mistake can lead to gas leaks, fires, or deadly carbon monoxide exposure. The risks of DIY furnace replacement are significant.

Professionals ensure code compliance and proper permitting, which is essential for safety and for future home sales or insurance claims. Furthermore, nearly all manufacturers require professional installation to keep warranties valid.

Professionals also guarantee proper sizing and performance. We perform detailed load calculations to ensure your system is not too big or too small, which prevents energy waste and ensures even comfort. The long-term cost savings from better efficiency, fewer breakdowns, and a longer system lifespan make professional installation a wise investment.
