Installing a new AC without checking line set length, refrigerant match, and cooling load is how Mertens homeowners end up with a unit that never performs to spec. We assess before we recommend equipment.
Many new installs never hit their rated efficiency, and sizing or line runs are usually why. We follow real numbers, not the easiest install.
What we don't cut corners on.
We calculate before we recommend.
Multiple efficiency options are available to fit different budgets.
You get a written labor warranty on top of manufacturer coverage.
We size and run lines to spec, since a bad run quietly kills efficiency.
From load calculation to startup commissioning.
A full assessment determines actual cooling demand, not a generic estimate.
SEER2 ratings get explained in plain terms so the decision is based on real numbers, not marketing language.
Line sets are sized and insulated to manufacturer spec, avoiding efficiency losses from a poor run.
Units get placed away from heat traps and debris for airflow and noise, not just wherever's convenient.
Charge, airflow, and temperature split all get verified after install, not just assumed correct.
Old systems get removed and disposed of properly, refrigerant recovered per EPA regulation.
What to expect on an install project.
We book an in-person cooling load assessment, since accurate sizing can't be done by phone.
A tech shows up with assessment equipment and evaluates the home for a direct evaluation.
Options are based on real data.
Installation is completed and warrantied.
Recent reviews from new system installs.
Compared quotes from four companies before deciding. This was the only one that showed me actual Manual J numbers instead of a flat price sheet.

We wanted the quietest unit available since our bedroom windows face the side yard where it sits. They steered us toward a model rated specifically for noise.
— I. Adeyinka, homeowner
Had a mini-split installed in a converted garage that never had ductwork. Clean install, didn't have to cut into any walls we cared about.
— C. Bergstrom, homeowner
Installed new rooftop units at two of our retail locations within the same week. Consistent process and pricing at both sites.

Common questions before a Ac Installation project.
An accurate size comes from an in-home load calculation, not square footage alone is the only reliable way to size correctly.
Depends on your climate and how long you'll own the home, we walk through the math.
A typical install wraps up in one day, longer for complex line runs.
Removed and disposed of with proper refrigerant recovery, to EPA standard.
Yes, both ducted and ductless options are available, chosen based on the property.
If something about how the unit was put in causes a problem down the line, that's on us to fix at no charge, on top of whatever the manufacturer covers on the equipment itself.
