AC Repair in Shawnee, KS

You rely on your HVAC unit to keep you cool during the summer, but it may not meet your expectations if it’s an older model. Replacing the unit is a big decision, especially considering it costs several thousand dollars. Learning more about when and if you should allows you to make informed decisions in the best interest of your home, comfort, and wallet.

What Is the Lifespan of an HVAC Unit?

An HVAC unit usually lasts 15 to 25 years. It’s a wide range, but its lifespan depends on several factors, especially the quality of the initial installation and how well the unit is maintained. Making good decisions from the beginning allows it to last as long as possible.

How Much Is It to Replace an HVAC Unit Before Summer?

The cost of replacing an HVAC unit can vary. There’s the price of the unit itself and the expense of labor. Getting an upfront estimate lets you know how much you would spend so that you can prepare accordingly.

Is Replacing It More Cost-Effective Than Repairing It?

That depends. Homeowners don’t need to replace an HVAC unit whenever something goes wrong with it. Repairs are a normal part of maintenance throughout its lifespan. However, components wear down over the years to where repairs will cease being effective, so you’ll eventually have to replace the unit.

The cost of repairs may get to the point where it no longer makes financial sense to continue doing them, and a replacement would be the more cost-efficient option. You pay more upfront but enjoy long-term reliability and likely a lack of repairs for years.

Should I Replace an HVAC Unit if It Still Works?

Just because an HVAC unit still turns on and blows cool air doesn’t mean it’s working correctly. Uneven cooling and diminished airflow are examples of that. We can evaluate your unit and determine if it’s working the way it’s supposed to and providing you with the summer cooling you need.

How Soon Before Summer Should I Replace My HVAC Unit?

Calling us at the end of winter or during spring is ideal. The closer it gets to summer, the harder it may be (although not impossible) to get the best appointment for your schedule. Many homeowners try to make appointments during the same time. We suggest calling us as soon as possible so we can assess your current setup, order the correct materials, and install them at your home before the summer temperatures start heating up.

Will an Older HVAC Unit Cool My Home as Well as a New One?

Older units don’t cool as efficiently as they once did; they lose their abilities as they age. A modern HVAC system is designed for maximum efficiency and provides more reliable cooling than your current old unit. With a new unit, you can have peace of mind that it will work as it should.

How Does a Failing HVAC Unit Impact My Summer Utility Bills?

Many homeowners will spot signs of a problem on their utility bills before noticing an issue with their unit. Your utility costs will increase even if your cooling usage hasn’t. Keep a close eye on your monthly bills and compare the charges month to month to see if you notice any changes.

Should I Replace My HVAC Unit if I’m Selling My Home During Summer?

Some homeowners view replacing the unit as an unnecessary expense, that there’s no point if they won’t even be living in the home much longer to reap its benefits. It’s not necessary to replace it if you’re selling your home, but you should consider it, especially if your unit is double digits in age.

Prospective homebuyers can perceive it as a fantastic advantage, a much-appreciated perk to be able to move in and immediately start cooling their home without stressing about if it will give out in the middle of a hot day. They don’t want to worry about the AC replacement process themselves and may be willing to pay extra for the convenience of it already being done for them. It can also signify that the rest of the home is well-maintained.

Should I Replace the HVAC Unit if I Just Bought a New Home in Summer?

If the unit is new or like-new, as in it’s 5 years old or younger, you usually don’t have to replace the HVAC unit. You may want to consider it if it’s between 5 and 9 years old, but it could go either way. Our HVAC technicians can evaluate its condition and provide a personal recommendation of whether it’s good as-is or if you should replace it.

If you’re moving into a new home and the unit is 10+ years old, it’s generally a good idea to contact us to replace it or negotiate it into the terms of the home’s sale. Older units generally need more repairs than younger units, so it may be better to spend that money on a new unit and have the peace of mind that it will cool your home properly.

What Are Common Signs My HVAC Is Failing in Summer?

Your HVAC unit will exhibit one or more signs that it may need replacing. Frequent repairs are a huge sign that it’s at the end of its life and will likely continue to be a money drain rather than contribute to sufficient cooling. You may also notice foul odors or worrisome sounds, like banging.

Additionally, your home might feel uncomfortably warm and/or humid, your unit may have poor or no airflow, and your utility bills may get more expensive than ever. We can inspect your unit and recommend a complete replacement for serious problems or thorough AC repairs if the issues are relatively minor.

How Do I Prevent Having to Replace a New Unit Sooner Rather Than Later?

Taking care of your HVAC system is the best way to ensure your unit keeps you cool for many more years. Self-inspections, maintenance, and professional inspections are the best ways to do that.

Do frequent self-inspections and closely observe the unit’s sounds, smells, and appearance. Listen if it’s making any odd noises or if there are any strange odors, like a burning smell. You should also look for physical damage, such as cracks on the exterior. Additionally, pay attention to the airflow and how cool your home feels. If both are inadequate, call us immediately, as there’s likely a problem. Don’t forget to change the filter every one to three months.

Professional inspections are also crucial. It’s ideal to call Air Care Heating & Cooling in spring so that we can make sure your unit will work as expected throughout summer; then, reach out again in fall so that we can prepare it for winter.
