The 5 Steps of AC Replacement

A Step-by-Step Guide to Your AC Replacement

Air conditioners are rather hardy mechanical systems that last 15 to 20 years, even longer if properly maintained. For this reason, many homeowners have never experienced the need to replace a heating and cooling system and do not know what to expect. Since unfamiliar experiences make us a little nervous, here is an AC replacement replication to let homeowners know what to expect.

First, it is extremely important to remember that systems last 15 to 20 years. Not knowing, or worse, ignoring these numbers, can lead to a lot of unnecessary discomfort. Failing to plan for a replacement can lead to the worst-case scenario for replacement—a catastrophic failure leading to an emergency replacement. Remembering these numbers can help a homeowner plan for a replacement. Most of the following steps can be planned before an air conditioner fails, avoiding the discomfort and inconvenience of doing without AC during the hottest days of summer.

From Breakdown to Brand New: Understanding The Replacement Process

So, what can you expect with an air conditioner replacement?

1. A major problem develops with the system. Many people will put up with paying higher energy bills, poor performance, or odd smells, but when the system ceases to cool and there is no repair available, something must be done. This type of failure often happens during the worst heatwave of the summer, since the temps above 100 degrees puts tremendous stress on a weakened system. Something gives, and the entire system will not function. Consulting with a technician may take a while, but the final decision might come as a shock, and an inconvenient shock to say the least.
2. The technician will gather some information and do a Manual J Load calculation to determine the size of the heating and cooling components needed to heat and cool the home year-round.
3. A bit of shopping ensues, determining the efficiency of the components (SEER for air conditioning, AFUE for heating components). Can your home take advantage of a heat pump system? A nominal price point with significant energy cost savings. Brands and fuel type for heating (natural gas or electricity), and any accessories, will need to be decided upon.
4. Are all the components in stock, or will some need to be shipped to the contractor’s location?
5. There is bound to be a little negotiation on the schedule. When can installation technicians and a family member be available for a day or two together?
6. Removal and installation usually take one day, two days for large or unusual systems. The old refrigerant will be removed from the system. The components will be disconnected from electricity, gas, and drains. The new components will be seated, installed, and reconnected to the appropriate networks. The new system will be recharged with the newest refrigerant available. The new system will be brought online and tested.
7. The installation technician will need access to an outside location to replace the condenser, inside the closet, attic, or crawl space to access the air handler, access to the thermostat, and finally, to various zones of the home to test performance/temperature changes.
8. The old components will be removed from the premises.

The steps necessary for a planned replacement are virtually the same. However, they can be planned in advance by a homeowner. This takes most of the questions, discomfort, and inconvenience out of the experience, making the process more pleasant.

AC replacement doesn’t have to be a stressful, last-minute emergency, especially not during a sweltering Houston summer. By understanding the typical 15-to-20-year lifespan of your unit and familiarizing yourself with the replacement process, you can proactively plan. This foresight allows you to make informed decisions about sizing, efficiency, and scheduling, avoiding the discomfort and higher costs often associated with sudden breakdowns. Taking these steps ensures a smoother transition to a new, efficient AC system, keeping your home cool and comfortable for years to come.
