General Questions
We serve all of St. Louis County and St. Charles County (including St. Charles City). We also service St. Louis City, but we don’t actively target it for marketing. If you’re not sure you’re in our area, give us a call and we’ll confirm.
Yes—our phones are answered 24/7 and you’ll always get a live person. When it’s a no-heat or no-cool situation, we do our best to book same-day repair appointments when availability allows.
We diagnose, repair, and install most major heating and cooling systems, including:
- Gas and electric furnaces
- Air conditioners
- Heat pumps
- Boilers
- Commercial rooftop units
Note: We do not work on geothermal systems, and we no longer provide ductless/mini-split service.
We answer calls right away and work hard to keep scheduling simple. For repairs, we aim for same-day appointments whenever possible. If we’re booked up, we’ll give you the soonest options and a clear arrival window.
Yes. After we diagnose the issue, we’ll explain what we found and give you a firm repair price before any work begins. No surprise hourly billing.
Our diagnostic fee is $89, which covers the trip to your home and the time it takes to diagnose the problem. Once we know what’s going on, we’ll quote the repair up front. (Pricing can change—call to confirm current rates.)
Yes. We stand behind our work with strong guarantees, including a service warranty and a service guarantee (if you’re not happy with our service, you don’t pay). We also offer installation guarantees for qualifying residential installs.
We provide free estimates on new equipment installations, and financing is available through Hearth.

Air Conditioning Repair & Service
Common causes include a dirty air filter, thermostat settings, a tripped breaker, low refrigerant, or a failed component like a capacitor. We’ll test the system and give you a clear, up-front repair price.
Freeze-ups are usually tied to airflow issues (dirty filter, blocked return, dirty coil) or refrigerant problems. Turn the system off to let it thaw and call us—running it frozen can cause more damage.
Check the thermostat mode and batteries, the furnace/air-handler switch, and your breakers. If those look good, it’s time for a diagnostic—many “no start” issues come down to electrical parts or safety controls.
Most diagnosis visits take about 60–90 minutes, depending on access and symptoms. If a part is needed, we’ll walk you through the options and the expected timeline.
Yes. We service most major brands and can help you decide the best path based on system condition and parts availability.
If the system is older, uses outdated refrigerant, has a major component failure, or you’ve had repeated repairs, replacement may be the better long-term value. We’ll lay out options so you can choose what fits your home and budget.
Yes. We install new equipment for homes and businesses, including system replacements and new construction projects. We also offer free estimates on new equipment installations.
Heating Repair & Service
Common issues include thermostat problems, a tripped safety switch, ignition failures, a dirty flame sensor, or control board trouble. We’ll test the system safely and pinpoint the actual cause.
This can be normal for a short time at startup, but ongoing cool air can point to burner/ignition issues, airflow problems, or a thermostat setting like “fan on.” We’ll diagnose it and explain what’s happening.
Short cycling is often caused by overheating due to restricted airflow (dirty filter, closed vents), a faulty flame sensor, or a sizing/venting issue. A diagnostic visit will identify the root problem.
We recommend a professional tune-up once per year, ideally before winter. It helps with safety, reliability, and efficiency. Ask about current seasonal tune-up pricing.
Yes. We diagnose, repair, and install heat pumps and boilers, along with gas and electric furnaces.
The heat exchanger separates combustion gases from the air you breathe. Cracks can create serious safety risks. We’re certified heat exchanger experts and take safety checks seriously on every heating call.
Yes. We install new heating systems and provide free estimates on new equipment installations. We’ll help you choose equipment that fits your home, comfort goals, and budget.
Indoor Air Quality
We offer indoor air quality solutions like air cleaners, air purifiers, energy recovery units, and airflow improvements—plus humidity control and duct cleaning when needed.
Yes. We install and service whole-home humidifiers and dehumidifiers (including Aprilaire products) to help your home feel more comfortable year-round.
If the filter looks dirty, airflow feels weak, or dust builds up quickly, it’s time to replace it. Many homes need a change every 1–3 months, but it depends on pets, allergies, and filter type.
Yes. Duct cleaning can help in situations like heavy dust buildup, recent remodeling, or airflow issues tied to dirty ductwork. We’ll tell you honestly if it’s likely to help based on your home and symptoms.
Air cleaners typically focus on capturing particles like dust and dander. Air purifiers may add additional technology to help reduce smaller particles and certain airborne contaminants. We’ll recommend what makes sense for your goals.
Energy recovery units help bring in fresh air while managing temperature and humidity, which can be useful in tighter homes. If you’ve got stale air, odors, or moisture issues, we can review whether this is a good option.
They often can. Better filtration, balanced airflow, and proper humidity control can reduce dust, help with allergens, and cut down on musty odors. We’ll help you pick the right upgrades without overselling.
Maintenance & Plans
Our agreements include two maintenance visits each year to keep your system running safer and more efficiently—one geared toward heating season and one toward cooling season.
Members receive discounts on repairs:
- Silver: 10% off
- Gold: 20% off

For most homes, we recommend maintenance twice per year—before summer cooling and before winter heating. It helps catch small issues early and keeps performance consistent.
Yes. We provide residential and commercial maintenance, including service and replacement of commercial HVAC equipment and rooftop units.
Yes. Regular service reduces surprise failures by spotting wear, cleaning critical components, and confirming safe operation. It’s also a good way to keep airflow and efficiency on track.
We run seasonal promotions from time to time (for example, a recent furnace precision tune-up special was $79). Call to confirm current availability and pricing.
- Change filters on schedule
- Keep supply and return vents clear
