HVAC Maintenance and Tune Ups in Osage Beach

Most of the emergency calls we get could have been prevented months earlier, for a fraction of what the emergency ended up costing. Maintenance is the least exciting thing we do. It's also the thing that saves people the most money.

The year

What your system needs, and when

Heating and cooling work runs on a calendar whether you keep to it or not. Here's the year as we schedule it in Mid-Missouri.

March to May
Get cooling ready
AC tune up and refrigerant check
Coil clean and condensate drain clear
Open up vacation properties for the season
The quietest time to book and the cheapest time to find a problem.
June to August
Keep it running
Filter changes every one to three months
Clear vegetation back from the outdoor unit
Midseason checks on rentals between guests
Peak season. Repairs get booked out and everybody calls the same week.
September to November
Get heat ready
Furnace tune up and heat exchanger inspection
Igniter, flame sensor and burner service
Carbon monoxide detector check
The single most valuable appointment of the year. Book it in October.
December to February
Protect the house
Watch for short cycling and rising bills
Keep vents clear and doors open to unused rooms
Check empty properties before a hard freeze
Emergency season. This is when the October appointment pays for itself.
What a tune up covers

Inside a full tune up

A proper tune up is a systems check. On a cooling visit that means refrigerant levels, coil condition, condensate drainage, electrical connections, capacitor health and airflow across the system. On a heating visit it's burners, igniter, flame sensor, gas pressure, and a heat exchanger inspection for cracks.

The point is finding the part that's about to fail while it's still a scheduled appointment rather than a 2am phone call. It also keeps most manufacturer warranties valid, which people discover too late when a compressor fails and the claim gets denied for lack of documented service.

For rental and vacation properties we'll work around guest turnovers and let you know what we found without you driving out.

No mystery

Here's the whole checklist

Plenty of companies sell a tune up without telling you what's included. That's how tune ups got a reputation as a way to get in your door. Ours is printed below in full. Compare it against anyone else's.

Cooling visit
Spring, before the first stretch of real heat
Refrigerant pressures read and compared against spec
Capacitor tested under load, not just looked at
Contactor inspected for pitting and burning
Condenser coil cleaned of cottonwood, grass and lake dust
Evaporator coil checked for restriction
Condensate drain cleared and the pan checked
Blower wheel and motor amp draw checked
Temperature split measured across the coil
Electrical connections tightened
Thermostat calibration confirmed
Filter changed or sized correctly if it's wrong
Heating visit
Fall, before the first hard freeze
Heat exchanger inspected properly for cracks
Burners cleaned and flame pattern checked
Flame sensor cleaned, the single most common no heat cause
Ignitor tested and resistance checked
Gas or propane pressure verified
Venting and flue checked for blockage and draft
Carbon monoxide checked at the appliance
Safety limits and pressure switches tested
Heat pump auxiliary strips tested if you have them
Blower and airflow checked
Thermostat heat cycle confirmed end to end
If we find something wrong, you hear what it is, what it costs and what happens if you leave it, before any work starts.

So is maintenance worth paying for?

We're not going to tell you a tune up pays for itself every single year. Sometimes we come out, everything checks fine, and you paid for peace of mind. That's a real outcome and we won't pretend otherwise.

What we will say is that the failures we get called out for in July and January are overwhelmingly the ones that were visible in April and October.

The real one
Catching the cheap part before it takes something expensive with it
A weak capacitor costs very little to replace on a scheduled visit. The same capacitor failing under load in August can overheat a compressor, and that's one of the most expensive components in the system.
The one you feel
Not being on the emergency list
On a holiday weekend or the first hard freeze, everybody calls at once. Being the house that doesn't need to call is worth more than the visit costs.
The safety one
The heat exchanger inspection
A cracked heat exchanger is the one HVAC problem that's dangerous rather than just expensive, and it's silent.
The quiet one
Keeping the warranty intact
Most manufacturer warranties require documented annual maintenance. People find that out at the worst possible moment, which is when they're trying to make a claim.

Maintenance questions

Book a visit: (573) 693-8863
How often should this be done?
Twice a year. Once before cooling season and once before heating season. If you have a heat pump it matters more, because that's the same equipment running all twelve months instead of half of them.
My system is new. Do I still need it?
Yes, mostly for the warranty. Most manufacturers require documented annual maintenance to keep coverage valid.
Do you service rentals and vacation properties?
A lot of what we do around the Lake is exactly this. Seasonal properties have their own failure pattern, so we time visits around opening and closing rather than the calendar.
Do I need to be there?
It helps, because we'd rather show you what we found than describe it over the phone. But if you're managing the property from out of town, we can work with an access arrangement and send you the findings in writing.
How long does a visit take?
About an hour for one system, done properly.
What if you find a problem?
You hear what it is, what it costs and what happens if you wait. Then you decide.
