AC unit change-out

Signs that indicate the need for an AC unit change-out

If you are not sure about an air conditioning unit replacement, here are some signs that could suggest that it is time to do it.

The unit makes an uneven cooling:

If when you turn on your HVAC system, you notice that there is only cooling in some areas of your building, but other rooms are warmer, this indicates a malfunction.

You have an old unit:

If you have between 10 or 15 years with the same AC unit, this could be time to make the change, as over time, HVAC systems become less efficient and, even worse, suffer constant breakdowns, increasing repair costs.

Your electric bill increased:

If the unit is not working correctly, it can improve the kW consumption per month in the building, which makes it less energy efficient, and implies a higher cost in the long run.

You hear strange noises:

One of the signs that least notice the owners are the noises and even strange smells when they have their AC units on, and these can be severe problems, which could alert you about a faulty motor or electrical failure.

Your AC is damaged frequently:

If your air conditioning system demands continuous repairs, this is a sign that its life is ending and, at any time, will stop working.

Preparing for an AC unit change-out

Understanding that a new HVAC system installation is a multi-phase process can help make the replacement experience easier and more comfortable and ensure an efficient job:
Let’s take them one by one!

Select a licensed HVAC contractor:

More is needed that the company has a good reputation; you need to have the skills and qualified technical expertise to perform a professional job with all the safety guarantees.

The unit makes an uneven cooling:

If when you turn on your HVAC system, you notice that there is only cooling in some areas of your building, but other rooms are warmer, this indicates a malfunction.

Evaluate the size of your unit

The contractor should help you select the best AC unit option considering the size of your home or building. In addition, he should consider factors such as the type of insulation, specific preferences according to the purpose of your building, etc.

Evaluate your existing unit:

Before proceeding with the replacement, the contractor must examine your HVAC, ductwork, wiring, and other aspects to see its condition and what needs to be removed, and also to see what areas are vulnerable in your property.

Establishing a budget:

A professional contractor will tell you the cost of the new unit, materials, ductwork, wiring, and installation cost and stick to it after assessing the area.

I recently had an AC unit replaced as well as all the duct work replaced. From the very first moment I made contact with Advanced Air to the final stages Advanced Air continued to impress. Th AC unit was a one day service but the duct work was a much larger job and took 4 days to complete as scheduled. The crew was always on time, very polite and professional. I would Highly recommend Advanced Air. I am a customer for life : )Jim H

I had such a great experience with Advanced Air Systems!!!! Scheduling was quick and easy, and they showed up right on time. Communication throughout the process was excellent from the friendly, helpful office staff to the Service Tech Christopher that came out to the house!Christopher was really fantastic—he not only diagnosed and fixed my AC issue, he took the extra time to clearly explain what went wrong and what I can do to prevent it in the future. That level of care and professionalism really stood out.The pricing was very reasonable for the service provided, and overall I couldn’t be happier. I highly recommend using Advanced Air Systems!

I have used other HVAC companies in the past and discovered Advanced Air Systems as a recommendation. I had used another HVAC company and after multiple visits and not fixing the problem and paying a lot of money someone recommended Advanced Air. Now I will only use Advanced air from now forward. Don't look any further and know they're a great company
