Question 1

Do you install LG furnaces, AC, and heat pumps in the Twin Cities?

Accepted Answer

Yes. Central MN Heating & Cooling is a licensed installer of LG residential furnaces, central air conditioners, and cold-climate heat pumps across the Twin Cities metro and Central Minnesota. Every install includes a Manual J load calculation so the equipment is sized correctly for your home — not just swapped tonnage-for-tonnage.

Question 2

How long does a LG furnace or AC installation take?

Accepted Answer

A straight furnace or AC swap on LG equipment typically takes 6–8 hours in one day. A full system change-out (furnace, AC, coil, and line set) usually runs 1–2 days. We protect floors, haul away the old equipment, and leave the mechanical room cleaner than we found it.

Question 3

What does a LG furnace replacement cost installed?

Accepted Answer

Most LG furnace replacements in the Twin Cities land between $4,500 and $9,500 installed, depending on AFUE rating, BTU size, venting, and whether modifications to gas, electrical, or ductwork are needed. LG AC replacements typically run $5,500–$11,000 installed. We always provide a written, line-itemed quote before any work begins.

Question 4

Does LG qualify for Xcel Energy and CenterPoint rebates?

Accepted Answer

Yes — most high-efficiency LG furnaces (95%+ AFUE with ECM blowers), SEER2-rated ACs, and cold-climate heat pumps qualify for current Xcel Energy and CenterPoint rebate programs, plus federal 25C tax credits up to $2,000 on qualifying heat pumps. We file the rebate paperwork for you at install.

Question 5

What's included in the warranty on a new LG install?

Accepted Answer

LG offers a 10-year parts limited warranty on registered residential equipment (registration must happen within 60–90 days of install — we handle it). On top of that, Central MN Heating & Cooling adds a 2-year labor warranty on every install, so you're not paying a tech to swap a part that's still under factory coverage.

Question 6

Do you repair LG equipment we already own — even if you didn't install it?

Accepted Answer

Yes. We repair and tune up every major brand including LG, regardless of who installed it. Our trucks carry common LG ignitors, flame sensors, inducer motors, capacitors, contactors, and ECM modules so most repairs are completed in a single visit.

Question 7

My LG furnace won't ignite or keeps short-cycling. What's wrong?

Accepted Answer

The most common LG no-heat calls we see are a dirty flame sensor, a cracked hot-surface ignitor, a clogged condensate trap (on 90%+ units), a failing pressure switch, or a plugged filter restricting airflow. Short-cycling is usually a flame-sensor or limit-switch issue. We diagnose, quote the repair, and waive the diagnostic fee when you approve the work.

Question 8

My LG AC is running but not cooling. Is it the refrigerant?

Accepted Answer

Not always. Before we add refrigerant, we check airflow (filter, blower, evaporator coil), the outdoor capacitor and contactor, and verify the indoor coil isn't iced over. If the system is actually low on refrigerant, that's a leak — adding refrigerant without finding the leak is throwing money at the problem. We pressure-test and quote the leak repair properly.

Question 9

How often should a LG system be tuned up?

Accepted Answer

Once a year for each side — furnace in fall, AC in spring. An annual LG tune-up keeps the factory warranty valid, catches small issues (weak capacitors, dirty flame sensors, low refrigerant charge) before they become no-heat or no-cool calls, and typically pays for itself in efficiency.

Question 10

How long does a LG furnace last in Minnesota?

Accepted Answer

Properly sized and maintained, a LG gas furnace lasts 18–22 years in Minnesota homes, and a LG central AC typically runs 12–17 years. Cold-climate heat pumps usually go 12–15 years. Annual tune-ups and a clean filter every 1–3 months meaningfully extend service life.

Question 11

When should I repair my LG system vs. replace it?

Accepted Answer

Our rule of thumb: if the unit is past 75% of its expected life AND the repair is more than 30% of replacement cost, replacement usually wins on total cost of ownership. We'll show you both numbers in writing — repair quote and replacement quote — so you can decide without pressure.

Question 12

Do you offer financing on a LG install or major repair?

Accepted Answer

Yes. We offer 0% promotional financing on qualifying LG installs and longer-term low-APR options on major repairs, with quick approvals so we can keep your home heated or cooled while paperwork is finalized.

Question 13

Do you offer emergency repair for LG no-heat or no-cool calls?

Accepted Answer

Yes — we run same-day and after-hours service across the Twin Cities. If your LG furnace is down in a Minnesota cold snap or your AC has failed in a heat advisory, call 651-395-3422 and we'll dispatch the next available tech.
