5 Tips for Choosing the Right Air Conditioner Replacement


Air conditioners are essential appliances that make the hottest days of summer bearable. However, prolonging the life of your old AC with extensive repairs might not be the right move. It costs you more for maintenance and cooling costs.

In many cases, an AC replacement will keep your home more comfortable while saving money on utility costs. Here are the main things to look at when choosing an AC replacement.

Make Sure to Get the Right Size

The most crucial individual element of choosing your next AC is selecting the correct size or fit for your home. Your living space has a specific cooling load, typically expressed in terms of power. That measurement is what’s going to determine the size of your AC replacement, but it’s no simple matter.

It’s easy to find a table online that will give you an approximate cooling load for the square footage of your home. But this is only one part of the puzzle. There’s so much more to consider, like the following:

  • Do you have more than one floor?
  • What type of foundation do you have?
  • Is your attic or roof insulated?
  • What is the thickness and construction of your exterior walls?
  • What are the average and high temperatures where you live?

You need a professional to apply these factors when sizing an AC replacement correctly.

If your AC is too small, you aren’t going to get enough cooling. As a result, your house will be too warm and have uneven cooling distribution. On the other hand, if the AC is too large, you’re going to be wasting money on an oversized and overpowered unit.

Evaluate Your Options Thoroughly

Replacing your current AC with a newer, more efficient model of the same size and type is probably the simplest option. But it isn’t your only option. You should consider how you could benefit from getting an AC replacement of a different type.

Many homes have central air conditioning that relies on ducts to circulate cool air. This system is great if you have it or have a home with ductwork already connected. Otherwise, it’s challenging to install in existing homes. It also presents a problem if you have expanded your home because the system might be too small.

If this is your situation, you might consider installing a mini-split air conditioner. These ductless units are incredibly efficient and offer excellent temperature control. They’re also easy to install, much easier than expanding an existing central system to account for expansions.

Choose Energy Efficient Models

One of the best reasons to get an AC replacement is the increased energy efficiency of newer models. Even if your older unit still provides adequate cooling, you could save a lot of money on cooling costs with a newer model.

Luckily, there is a standard metric for AC efficiency: The Seasonal Energy Efficiency Rating (SEER). This number ranges from 13 to 21 for ACs, with 21 being the best. Think of it as comparing a new car’s MPG to find the best choice.

With how much energy an air conditioner uses, it’s going to be a considerable portion of any utility bill. That means that even a slight improvement in efficiency will provide significant savings over time. So always choose a highly efficient AC replacement.

Determine Your Budget

When you start googling for an “AC replacement near me,” try to get a clear idea of how much you’re looking to spend. That is going to impact your options. Consider long-term and short-term budgeting together because you must consider energy savings. 

If a more expensive unit with higher efficiency, or more advanced units like mini-splits, are beyond what you can afford right now, you might consider financing. Energy savings can lead to savings in the long run, so your AC replacement is a type of investment.

Take Maintenance Into Consideration

Every type of air conditioning system requires some maintenance to last longer and provide optimal cooling. When making your decision, consider how significant the maintenance commitment is going to be.

Choose a model from a reliable brand with a reputation for quality AC units. This will ensure that your AC replacement won’t require excessive repairs. Annual AC tune-ups can lower your maintenance costs by catching any problems before worsening and providing optimal energy efficiency.

I cannot say enough about this company!!! Their only concern is that you are up and running again with no worries. I’ve had Kyle the plumber, and Josh their electrician out here and both are polite, well trained and you can tell they truly care about getting you back in service. Great service, well trained caring staff! I will never go anywhere else!

Nick Boudreux

Had a well pump that was shorting out and pretty much had no water. Adrian from this company not only got out next day but was great to work with. He was very friendly and knowledgeable I would definitely recommend this company to anyone that needs work done! Thanks again guys!

T. Minasian

These are the after photos of the Rinnai tankless water heater installation and vent to the outside. It was important to me that the crew was able to use the existing vent hole to the outside to run both the intake vent pipe and the outside vent pipe. It made the job very clean and did not change the appearance of the outside wall. A shout out to Mike E, Caleb, Josh & Corey

K. Bernardo

We’re first time home owners and needed help with some plumbing and adding a filter system. They were able to get a technician scheduled to our house within a day or so of me contacting them. Mike was super helpful and was able to complete all the jobs in a timely manner, and also cleaned up the areas he was working in. Overall a great experience and would definitely use them for future jobs.

S. Baraket

Never used Paul The plumber company before but I’m glad I did. Very courteous, professional and pleasant from the answering service (Diane) to employees (Jeremy). They diagnosed the problem and fixed it in no time. Very happy and satisfied with their service. Definitely will use again. Thank you

W. Chepren

I made an appointment on line the morning of July 31 and two trucks showed up at 1:00 pm right on time that same afternoon. Both guys were friendly and very knowledgeable. They quickly found the source of the wet patch on my ceiling which wasn’t the plumbing but a problem with the shower curtain. This is the second time I have called Paul. Both times I got outstanding service and will always call on Paul the Plumber for any plumbing problems in the future. Very reasonable cost for the visit.

S. DesMarais

Josh was amazing. He was able to install my ring doorbells with no issues. He also did a great check of my homes smoke detectors and a few electrical plugs. He was thorough, Knowledgeable, and easy to work with. I would definitely use them again.

V. Vincze

We had an issue with our water…too hard, calcium deposits, and very little pressure in our master bathroom shower only. The techs (Mike E. & Tyler S.) arrived right on time. They were friendly and very personable. After installing our whole house filtration system and successfully finding the issue with our master bathroom, they left the work areas in pristine condition. They were meticulous in their work, and I highly recommend them for any plumbing needs!

J. Shea

John was wonderful. He found the problem right away and fixed it. He checked other outlets just to make sure I would be safe. He explained different programs the company offers also. I’m very happy.

K. MacCallum

First time customer, and am very pleased with the whole experience. The highlight was definitely with the technicians assigned to the job and their work – Tyree and Corey were clean, polite, well-informed, and very helpful with some of the questions I had along the way. Their work appears to be top-notch, and they made sure no mess was left behind. Will definitely be calling and requesting these two again on any future needs.

D. Lefort

Arrived as scheduled to fix a leak from the shower valve. Tried to fix old 30 or 40 year old unit but had to replace with a new one. Quality work, parts and cleaned up when they were done. Would definitely use again.

Michele

I’ve used Paul the Plumber twice now for electrical issues and they have been wonderful each time. They are fast, polite, knowledgeable, and very fairly priced. They explain everything well and answer my questions thoroughly and I feel safer now knowing what was causing my electrical issues and having it fixed! I will be using Paul the Plumber for all my household needs going forward

Thanks to Mike Vallee from Paul the Plumber for responding to this new customer’s call so quickly. He was courteous, thorough, explained the repair he was doing and left the work area spotless. I highly recommend Paul the Plumber (and Mike!) to anyone looking for a reliable plumbing company.

D. Weaver

What a fantastic business. Helped us work with our water district in resolving meter replacement issues. They also fixed a pipe leak that had developed over time. Caleb was wonderful and answered our questions as well as working with the water district engineer on the meter issues. So easy to work with.

H. MacPherson

I would recommend Paul the Plumber 100%. They offered same/next day service. They were friendly, professional and quick – from the office staff to the technicians. Overall an amazing experience from start to finish.

J. Wojo

DJ from PTP was incredibly helpful and knowledgeable. My shower was not draining and it became a bigger project than I thought it would and they came out quickly and were able to fix my problem. Then when my water heater had a slow leak they came back out quickly to attend to it and fix my problem. I really appreciate their hard work. Thank you so much!! Would definitely recommend them.
