Frequently asked

Answers from the crew, not a chatbot.

The questions St. Louis homeowners ask us most. If yours isn't here, call us — we'd rather talk it through than guess what you need.

Pricing & Quotes

Most common AC repairs in St. Louis run between $180 and $650 depending on the part — a capacitor or contactor is on the low end, a compressor or coil replacement is higher. We always give you a flat, up-front quote before we start any work, so you know the exact price before we lift a wrench.

Yes, our standard diagnostic visit is $89, and that fee is waived for Comfort Club members and for any customer who goes ahead with the repair. We don't bill by the hour — the diagnostic covers the trip, the full 20-point inspection, and a written quote for any work needed.

A complete new high-efficiency system in the St. Louis market typically runs from $4,900 to $9,500 depending on equipment tier, your home's square footage, and any ductwork or electrical upgrades needed. We size every install with a real Manual J load calculation and offer financing on approved credit.

Emergency Service

Yes — our emergency line rings a technician, not a call center, twenty-four hours a day, seven days a week. Most emergency calls inside the St. Louis city limits are reached in under 45 minutes, and Comfort Club members never pay an after-hours surcharge.

First, check your thermostat batteries and your breaker, and make sure the furnace switch near the unit is on — that resolves about one in five no-heat calls. If those are fine, call us right away at (314) 328-4371 so we can get a tech dispatched before the house gets dangerously cold.

Comfort Club members pay no after-hours surcharge at all, ever. For non-members, emergency after-hours calls carry a modest premium that is quoted up front before we roll the truck — never a surprise on the invoice.

Maintenance & Lifespan

Twice a year is the right cadence for our climate — a spring cooling tune-up before the humid St. Louis summer and a fall heating check before the cold snaps hit. Our Comfort Club bundles both visits with priority dispatch and a discount on any repairs we find.

In the St. Louis area, a well-maintained air conditioner typically lasts 12 to 17 years and a furnace 15 to 20 years. Humidity and heavy summer use shorten A/C life, which is exactly why the twice-yearly tune-ups matter so much here.

As a rule of thumb, if a repair costs more than half the price of a new system or your unit is past the 10-to-12-year mark, replacement usually makes more sense. We'll always tell you honestly when your current system has good years left — we'd rather earn your trust than sell you a unit you don't need.

Service Area & Scheduling

We serve a 45-mile radius across the St. Louis metro, including St. Louis city, Florissant, Chesterfield, St. Charles, Kirkwood, and the surrounding communities. If you're not sure whether you're in our area, just call — if we can't reach you fast, we'll tell you straight up.

Most calls inside the metro are reached in under 45 minutes during business hours, and Comfort Club members get priority same-day dispatch even on our busiest days. For emergencies, we aim to have a tech rolling within the hour, day or night.

Yes, Dee's Heating & Cooling LLC is fully licensed and insured in Missouri, and our technicians are NATE-certified and factory-trained on the major brands we service. You can verify our license status and insurance any time — just ask.
