Sizing Comes First: Getting AC Installation Right in Lindon
An air conditioner that is too large for a home short-cycles, turning on and off rapidly without ever properly removing humidity. An air conditioner that is too small runs constantly and still cannot keep up on the hottest afternoons. Both mistakes cost money every month and shorten the life of the equipment. This is why any AC installation we perform in Lindon starts with a load calculation rather than a guess based on square footage alone.
At Gillette Services - Plumbing, Heating and Air Conditioning, we measure what actually affects cooling demand in your specific house. That includes window placement and orientation, insulation levels, ceiling height, the number of occupants, and how much sun each room takes during the day. A home on a shaded lot with newer windows needs a different system than a comparable home with large west-facing glass. Getting this step correct is the single most important factor in how well your new central air installation will perform for the next fifteen years.
What Homeowners Ask Before Replacing a System
Most people do not think about their air conditioner until it stops working. When it does, the questions come quickly, and they deserve straight answers. Below are the concerns we hear most often, along with how we approach each one.
- Should I repair or replace? If a system is more than 12 to 15 years old, uses discontinued refrigerant, or needs a repair that costs a large fraction of a new unit, replacement usually makes more sense over time.
- How long does installation take? A straightforward replacement of an existing central air system is often completed in a single day. Projects involving new ductwork or electrical upgrades take longer.
- Will a bigger unit cool better? No. Correct sizing beats oversizing every time. An oversized unit leaves your home cold but clammy because it never runs long enough to pull moisture from the air.
- What efficiency rating do I need? A higher SEER2 rating lowers your operating cost, but the right number depends on how much you run the system and how long you plan to stay in the home.
We walk through each of these with you before any work begins. As an air conditioning company that is locally owned and family-operated, we would rather spend the extra time explaining options than sell you equipment that does not fit your needs. That approach reflects who we are as “Your Homegrown Service Pros.”
Our Installation Process Step by Step
A clean installation is what separates a system that lasts from one that struggles. Cutting corners on the connections, the electrical work, or the refrigerant charge creates problems that show up months later. We follow a consistent sequence on every air conditioner installation so nothing is skipped.
- Assessment and load calculation: We measure your home and confirm the correct system capacity before recommending equipment.
- Removal of the old unit: We recover old refrigerant according to regulations and remove the existing equipment without damaging your property.
- Setting and connecting the new system: We level the outdoor condenser, install the indoor coil, and make all line-set, electrical, and condensate connections to code.
- Vacuum and charge: We pull a deep vacuum to remove moisture and air from the lines, then charge the system to the manufacturer’s exact specification.
- Testing and walkthrough: We verify temperature split, airflow, and safety controls, then show you how to operate and maintain the new system.
Every one of these steps matters. A missed vacuum step, for example, leaves moisture in the refrigerant lines that turns acidic and eats away at the compressor. Details like this are why we take responsibility for the full result rather than rushing to the next job.
Technical Details That Affect Long-Term Performance
Refrigerant charge tolerance is tight. Even a small overcharge or undercharge reduces efficiency and stresses the compressor. We measure superheat and subcooling during installation to confirm the charge is exactly where the manufacturer wants it. We also check the temperature difference between the return and supply air, which should typically fall within a specific range that confirms the system is removing heat as designed.
Ductwork is the other half of the equation. A perfect air conditioner connected to leaky or undersized ducts will never deliver its rated performance. During any central air installation, we inspect the existing duct system for leaks, restrictions, and poor design. When needed, we recommend sealing or modifications so the conditioned air actually reaches the rooms you live in.
