Conventional ACs and furnaces don't usually require installing a new air handler. That's not the case with an electric heat pump. Its function and design generally require you to purchase an air handler with the system.
As long as you can get a new AC setup that matches the airflow the air handler can put out, you can just replace the AC and not the air handler.
The $5,000 rule is a rule of thumb in the HVAC industry to help homeowners decide whether HVAC repair or HVAC replacement makes more sense in the long run. The $5,000 rule: Multiply the age of your equipment by the estimated repair cost. If the number is more than $5,000, then you should consider replacing your unit.
An air handler costs $1,500 to $3,400 to replace, depending on the ton size, brand, and type. Air handler prices are $700 to $1,600 for the unit alone, plus $800 to $1,800 for replacement labor. Air handler fan coil units from top brands like Trane, Carrier, and Lennox cost the most.
Normally, an air conditioner uses the furnace's blower motor, so no air handler is needed.
You can expect an HVAC system to last for anywhere from 15 to 20 years, maybe even longer, said Seattle-based designer and home renovation expert Eric Goranson, host of the Around the House podcast and nationally syndicated radio show. "It really depends on how well you service and maintain that system," he said.
Usually, an air conditioner uses the furnace's blower motor, so no air handler is required. However, in environments where home heating is not required, an air conditioner may be the only HVAC equipment present. In this situation, the indoor air handler runs in conjunction with the outside unit, called the condenser.
We've already explained how a dirty air filter can cause weak air, but did you know that holes or large cracks in an air handler can also contribute to this problem? They can also contribute to reduced air quality by allowing mold and mildew to take root and grow.
Homeowners insurance covers HVAC systems when the damage is a result of a covered disaster or peril, including high winds, fallen trees, theft, hail or even a fire. So if lightning strikes your unit and damages its electrical components, your homeowners insurance policy would probably cover it.
Usually, it is a quick fix, but sometimes the failure can be caused by a much bigger problem. The most expensive part of an AC unit to replace and repair is the air compressor.
The New Regulations
Starting January 1, 2025, all new residential air conditioners and heat pumps must utilize A2L refrigerants. Older refrigerants like R-410, which are likely the refrigerant used by your current system, are being phased out.
If your aircon is older than 10 years and plagued with ongoing issues, you might want to consider replacing your air conditioner. A benefit of replacing your aircon is that you will get a more energy efficient model which would ultimately save you a lot of money on power bills.
Even if components are worn, there's a better option than replacing the entire unit: refurbishing the AHU to make it work like new. Trimark Mechanical's extensive experience in air handler refurbishment cuts costs while shaving weeks (even months) off replacements.
Air handlers move air throughout HVAC systems instead of a furnace. These appliances look very similar and typically mount in the same location as an air handler.
HVAC and home insurance
A homeowners policy may cover your HVAC in two ways: either through the dwelling coverage or the personal property coverage on your policy. Dwelling coverage may help pay to repair or replace a built-in unit since it's considered part of the home's structure.
Earthquake, flood, mold, earth movement, and “wear and tear” are some of the perils that are usually excluded. When an insurer writes your homeowners coverage, the insurer is legally obligated to offer you earthquake coverage for an additional premium.
According to HomeGuide.com, the average cost to replace the HVAC units is $5,000 to $11,000; to replace the units with ductwork runs between $7,000 and $16,000 in total.
Your typical central air conditioning connected to an air handler and using ductwork can last as long as 30 years with good luck and maintenance but will generally need to be replaced somewhere between 10 and 20 years.
Air handler replacement averages $2,300, with most homeowners paying between $1,500 and $3,400. Unit costs vary from $600 to $2,100 or more depending on size, type, brand, and other factors. Hiring an HVAC technician for installation represents about 50% of total project costs.
The U.S. Department of Energy recommends that homeowners replace their HVAC system every 10 to 15 years. Although heating and cooling systems are meant to endure heavy usage, their components will start to wear out after 10 years.
If you've been experiencing unusual noises, inadequate cooling or heating, excessive dust and poor indoor air quality, escalating energy bills, frequent repairs, aging system, insufficient airflow, or uneven temperatures in your home, it may be time to consider replacing your air handler.
Unfortunately, yes, you should replace your air handler and condenser at the same time if one or the other fails.
you can expect to spend nearly INR 1 lakh to 1.5 lakh, which is considerably less compared to installing split ACs throughout the flat. By installing a central AC, you can expect quicker and more efficient cooling for the entire house, thereby putting away the need for independent AC units in various rooms and areas.
