Why Full Time Uses AirQuest Equipment

AirQuest isn't the brand name you see on every billboard, and that's part of why we chose it. The equipment is built by Carrier, performs reliably in Minnesota's heat and humidity, and comes at a price point that doesn't require you to overpay for a logo. As an AirQuest Elite Dealer, Full Time Heating and Cooling qualifies our customers for extended No Hassle Replacement coverage that goes two years beyond the standard manufacturer warranty on qualifying systems. We're not going to tell you AirQuest is the fanciest option on the market. We'll tell you it's a dependable system at a fair price, and that the warranty backing it is real. Check out our cooling services page if you want the full picture on what we offer for AC.

What the Installation Process Actually Looks Like

Here's how a typical AC installation goes with Full Time. First, we assess your existing system, ductwork condition, and home size before we ever order equipment. If your duct system has a leak problem or a static pressure issue, a new condenser won't fix that, and we'll tell you upfront instead of letting you figure it out after the fact. Once equipment is selected, the same two-person crew handles the full installation. That means the refrigerant line set, coil installation on your air handler or furnace, electrical connections, lineset insulation, pad and condenser placement, and a full system test before anyone leaves your property. A thermostat upgrade is worth considering at the same time, since a properly matched smart thermostat can meaningfully improve efficiency and comfort. Jason stops by at the end of every installation to inspect the work personally. That's not a talking point, it's how every job closes.

What Drives the Cost of a Central AC Installation

Four factors move the price more than anything else. First, equipment size. A 2-ton system for a 1,000-square-foot rambler costs less than a 4-ton system for a two-story with a finished basement. Second, ductwork condition. If your existing ducts are leaking, undersized, or poorly routed, that work needs to happen before or during the install. Third, efficiency rating. Higher SEER2 equipment costs more upfront and saves money over time, and we can walk you through the math on payback period. Fourth, refrigerant line length and routing. A condenser placed 40 feet from the air handler costs more to connect than one sitting directly adjacent. We'll cover what's driving cost on your specific home before you commit to anything.

When Repair Still Makes Sense Before You Replace

Not every failing AC system needs to be replaced. Some do. Some don't. If your system is under ten years old and the compressor hasn't failed, a repair is almost always worth pricing out first. Age and refrigerant type matter a lot. Systems running on R-22 refrigerant, which hasn't been manufactured since 2020, are expensive to service and getting more so every year. We'll tell you honestly which side of that line your system sits on. We don't pay our technicians to recommend replacement, so you'll get a straight answer either way. If a repair is the right call, we'll say so. If you'd like to understand your AC replacement options in more detail, that page walks through when replacement makes more financial sense.

Things That Make a Real Difference on AC Performance

Details below
The details that separate a good installation from one you'll regret in three years.

Proper Equipment Sizing

An oversized AC unit short-cycles, meaning it cools fast and shuts off before it pulls humidity out of the air. You end up cold and clammy. An undersized unit runs constantly and can't keep up on 90-degree days. Sizing is calculated from your home's square footage, insulation, window area, and orientation, not guesswork.

Matched System Components

The condenser and the evaporator coil need to be matched for the same tonnage and refrigerant type. Mismatched components reduce efficiency, stress the compressor, and can void warranty coverage. Full Time specs matched systems every time, not whatever coil happens to be in stock.

Refrigerant Charge Verification

Low refrigerant at startup is one of the most common installation errors and one of the least visible until summer peaks. We verify charge by weight and pressure on every new installation before the system runs.

Indoor Air Quality Pairing

A new AC installation is the right time to look at your air filtration setup. A properly spec'd filter or purification system works with your new equipment instead of against it. Worth a five-minute conversation before the crew leaves.

FAQ Common questions

Frequently Asked Questions

Answers below
What is the average cost to install an AC unit? +
It depends on the system and the home. High-efficiency systems, larger homes, or installs requiring significant ductwork modification cost more. Equipment is only part of the total. The labor, refrigerant, line set, electrical work, and permit fees are what most estimates underquote. Every job is different, contact Full Time Heating and Cooling for an accurate estimate.
How much will it cost to install AC? +
What moves the number on a central AC installation is equipment size, efficiency rating, ductwork condition, and how far the refrigerant line set needs to run. We give you a specific number after seeing your home, not before. Every job is different, contact Full Time Heating and Cooling for an accurate estimate.
How much does it cost to install an air conditioner? +
A complete central air conditioner installation in the Twin Cities metro covers equipment, labor, refrigerant, electrical, and permits. Ductless mini split systems for single rooms or additions are a different scope, priced by zone count. Homes without existing ductwork needing a full central air retrofit run significantly higher. Every job is different, contact Full Time Heating and Cooling for an accurate estimate.
How long does a central AC installation take? +
Most residential central AC installations take four to eight hours with a two-person crew. That covers condenser placement, coil installation on an existing furnace or air handler, line set connection, electrical disconnect, refrigerant charge verification, and full system startup testing. Homes needing ductwork modification or electrical panel work take longer. We don't hand off to a different crew mid-job.
What SEER2 rating should I look for in a new AC system? +
The federal minimum for the North-Central region is 14.3 SEER2. Most homeowners planning to stay in their home for a decade or longer see real payback from stepping up to 16 or 18 SEER2. We can run the numbers on payback period based on your actual energy bills. The right answer depends on your home, your usage, and how long you plan to stay.
Does a new AC installation require a permit in Minnesota? +
Yes. Most Minnesota municipalities require a mechanical permit for new AC installations, and some require a separate electrical permit for the disconnect and circuit work. Full Time handles the permit process. Skipping permits isn't something we do, both because it's a code violation and because it creates real problems when you sell the home and the inspection turns up unpermitted HVAC work.
