Replace Furnace And Ac At Same Time Cost

It's a scenario many homeowners dread: waking up to a house that's either freezing cold or unbearably hot, depending on the season. Your furnace or air conditioner has given up the ghost. But then the question arises: Should you replace both the furnace and AC at the same time? And perhaps more importantly, how much will that cost? This article will guide you through assessing your situation and understanding the factors involved in this significant home improvement decision.

Identifying the Problem: Is it Really That Bad?

Before jumping to conclusions about needing a full replacement, let's try to diagnose the issue. Start by identifying the specific problem you're experiencing.

Furnace Troubles

Here are some common furnace problems:

No Heat: The furnace isn't producing any heat at all.
Weak Airflow: The air coming from the vents is weak or barely warm.
Strange Noises: Banging, rattling, or screeching sounds coming from the furnace.
Pilot Light Issues: The pilot light won't stay lit (for older furnaces).
Burning Smell: A persistent burning smell when the furnace is running.
Frequent Cycling: The furnace turns on and off frequently.

Air Conditioner Woes

Common AC problems include:

No Cooling: The AC isn't cooling the house.
Weak Airflow: The airflow from the vents is weak.
Warm Air: The AC is blowing warm air.
Loud Noises: Grinding, hissing, or buzzing noises from the AC unit.
Leaks: Water leaks around the indoor or outdoor unit.
Frozen Coil: Ice buildup on the outdoor unit's coils.

DIY Troubleshooting: A Step-by-Step Approach

Now, let's try some simple troubleshooting steps you can do yourself. Safety first! Always turn off the power to the furnace or AC unit before inspecting it.

Without Tools: Quick and Easy Checks

These checks don't require any tools and can often reveal simple fixes:

Check the Thermostat: Ensure the thermostat is set to "Heat" or "Cool" and the temperature is set correctly. Make sure the batteries are good! A dead thermostat is a surprisingly common culprit.
Check the Air Filter: A dirty air filter restricts airflow and can cause numerous problems. Remove the filter and hold it up to the light. If you can't see through it easily, it needs to be replaced. This is the most common DIY fix!
Check the Circuit Breaker: Locate the circuit breaker panel and make sure the breaker for the furnace or AC hasn't tripped. If it has, reset it. If it trips again immediately, there's a more serious electrical problem.
Check the Vents: Ensure all vents are open and unobstructed. Blocked vents can restrict airflow and reduce efficiency.
Outdoor Unit (AC): Visually inspect the outdoor AC unit. Remove any debris like leaves, branches, or grass clippings that may be blocking airflow.

With Basic Tools: A Little More Investigation

These checks require a few basic tools, but are still within the reach of most homeowners.

Multimeter (Voltage Check): (Caution: Electricity can be dangerous!) If you're comfortable working with electricity, you can use a multimeter to check for voltage at the furnace or AC unit. Follow the manufacturer's instructions for safe testing procedures. *If you are not comfortable with this step, skip it and call a professional.*
Vacuum Cleaner (Cleaning): Use a vacuum cleaner to carefully remove dust and debris from around the furnace or AC unit. A clean unit runs more efficiently.
Fin Comb (Straightening Fins - AC): If the fins on the outdoor AC unit are bent, you can use a fin comb to straighten them. This improves airflow and efficiency.
Screwdriver (Panel Removal): Use a screwdriver to remove access panels on the furnace or AC unit to visually inspect the internal components. Look for obvious signs of damage, such as burned wires, cracked components, or leaks. Remember to turn off the power first!

When to Call a Professional: Knowing Your Limits

It's crucial to recognize when the problem is beyond your DIY capabilities. Here are some situations that require a professional HVAC technician:

Refrigerant Leaks: Handling refrigerant requires specialized equipment and training.
Electrical Issues: Diagnosing and repairing electrical problems within the furnace or AC unit can be dangerous.
Gas Leaks: If you suspect a gas leak, evacuate the house immediately and call the gas company and a qualified HVAC technician.
Major Component Failure: Replacing components like the compressor, heat exchanger, or blower motor requires specialized knowledge and tools.
Unfamiliar Sounds or Smells: Persistent strange noises or burning smells should be investigated by a professional.
If your unit is still under warranty: Attempting repairs yourself may void the warranty.

The Big Question: Replace Both at Once?

Now, let's address the central question: Should you replace your furnace and AC at the same time? Here's a breakdown of the factors to consider:

Age of the Units

This is the most important factor. If both your furnace and AC are over 10-15 years old, it's generally a good idea to replace them both, even if only one has failed. Older units are less efficient and more prone to breakdowns. Replacing them together offers several benefits:

Improved Efficiency: New furnaces and ACs are significantly more energy-efficient than older models, saving you money on your utility bills.
Matching Systems: When you replace both units at the same time, you can ensure that they are properly matched in terms of size and efficiency. This maximizes performance and comfort.
Avoid Future Headaches: If one old unit fails, the other is likely to follow soon after. Replacing both now can prevent future breakdowns and costly repairs.
Installation Savings: Replacing both units at the same time can often result in lower installation costs, as the HVAC technician only needs to make one trip.

Condition of the Units

Even if your units are relatively young, their condition matters. If one unit has failed due to a major component failure, it may be a sign that the other unit is also nearing the end of its lifespan.

Efficiency Ratings

Older furnaces and ACs have lower efficiency ratings (AFUE for furnaces and SEER for ACs). Upgrading to newer, more efficient models can significantly reduce your energy consumption and lower your utility bills. Consider the long-term cost savings when making your decision.

Refrigerant Type

Older AC units may use R-22 refrigerant, which is being phased out due to environmental concerns. If your AC uses R-22 and needs a major repair, it may be more cost-effective to replace it with a newer unit that uses R-410A refrigerant, which is more environmentally friendly and readily available.

Your Budget

Of course, your budget is a major consideration. Replacing both units at the same time is a significant investment. However, consider the long-term cost savings from improved efficiency and reduced repair costs. You may also be able to take advantage of financing options or rebates to make the purchase more affordable.

Understanding the Cost: What to Expect

The cost of replacing both a furnace and AC can vary widely depending on several factors:

Size of Your Home: Larger homes require larger, more powerful units, which cost more.
Efficiency Ratings: Higher efficiency units cost more upfront but save you money on your utility bills over the long term.
Brand and Model: Different brands and models have different price points.
Installation Costs: Installation costs can vary depending on the complexity of the job and the location of your home.
Geographic Location: Prices can vary depending on your geographic location.

General Cost Estimates (These are rough estimates and can vary significantly):

Furnace Replacement: $3,000 - $7,000
AC Replacement: $4,000 - $8,000
Combined Furnace and AC Replacement: $7,000 - $15,000+

Factors that can increase the cost:

Ductwork Modifications: If your existing ductwork needs to be modified or replaced, this will add to the cost.
Permits and Inspections: You may need to obtain permits and inspections for the installation, which can add to the cost.
Difficult Access: If the furnace or AC unit is difficult to access, this can increase labor costs.
Smart Thermostats or Other Upgrades: Adding smart thermostats or other upgrades will increase the overall cost.

Getting Multiple Quotes

It's essential to get at least three quotes from different HVAC contractors before making a decision. This allows you to compare prices, services, and warranties. Be sure to ask each contractor for a detailed breakdown of the costs, including the cost of the equipment, installation, and any other fees.

Questions to Ask HVAC Contractors:

Here are some important questions to ask HVAC contractors when getting quotes:

What size furnace and AC unit do you recommend for my home?
What are the efficiency ratings of the units you are recommending?
What is the warranty on the equipment and labor?
Are you licensed and insured?
Do you offer financing options?
Can you provide references from previous customers?

Making the Decision: Informed and Confident

Replacing your furnace and AC is a significant decision, but by understanding the factors involved and taking a methodical approach, you can make an informed choice that will keep your home comfortable and your energy bills low for years to come. Don't be afraid to ask questions, do your research, and trust your instincts. A well-informed homeowner is an empowered homeowner. Remember, when in doubt, always consult with a qualified HVAC professional.
