What’s Actually Included in an HVAC Tune-Up in Commerce City?

An HVAC tune-up in Commerce City includes a full inspection, cleaning, and performance test of both your furnace and AC. For example, each seasonal visit runs about $75 to $150 individually. Meanwhile, the 360 HVAC Maintenance Plan bundles both tune-ups plus 24/7 emergency service and priority scheduling for a flat $189 a year.

Learning how to prepare your AC for summer is the single best thing Denver homeowners can do before the first heat waveAn HVAC tune-up in Commerce City is a full inspection, cleaning, and performance test of your heating and cooling system, run twice a year to catch small problems before they turn into big ones. In short, most homeowners want to know what really happens on that visit before they book one. Below, this guide walks through the exact checklist by system, how long it takes, what it should cost, and how the 360 HVAC Maintenance Plan folds two full tune-ups plus a lot more into one flat $189 per year.

At 360 HVAC Pro, our technicians run a real hands-on tune-up on every visit. Specifically, that means we clean, test, and inspect every safety-critical component. Then we hand you a written summary of what we checked and found. Because we work without commission quotas or upsell pressure, the goal of a tune-up visit is to keep your system healthy, not to walk out with a list of things to sell you.

What’s Actually Included in an HVAC Tune-Up in Commerce City?

A real HVAC tune-up in Commerce City covers three things every visit: a full inspection of both your heating and cooling systems, a hands-on cleaning of the parts that get dirty and cause failures, and a performance test to confirm the system runs safely and at rated efficiency. In addition, every visit includes a safety check for carbon monoxide risk and a written summary of the results.

Because HVAC is really two systems in one, the checklist splits by season. Specifically, your AC gets a spring tune-up before cooling season, and your furnace gets a fall tune-up before heating season. Below is the exact checklist a licensed tech should be running on each side.

The Cooling Side: What Techs Check on Your AC

A spring AC tune-up in Commerce City runs through the cooling system top to bottom. Specifically, here’s what a real tech covers:

Air filter check and replacement. A dirty filter is the top cause of preventable AC breakdowns.
Refrigerant level and pressure check. Confirms the charge matches manufacturer specs.
Evaporator coil inspection and cleaning. Dust and pollen coat the coil in Commerce City’s dry, dusty air.
Condenser coil inspection and cleaning. The outdoor unit fills with cottonwood fluff, leaves, and grit.
Condensate drain line clearing. A clogged drain triggers safety shutoffs and can damage the air handler.
Airflow testing. We measure this at both supply and return to catch duct issues early.
Electrical connection tightening. Vibration loosens terminals over time, which causes intermittent failures.
Capacitor testing. A weak capacitor is one of the most common summer failures.
Blower motor inspection and lubrication. Extends motor life and reduces energy draw.
Thermostat calibration. Confirms your set temperature matches actual room temperature.
Full cooling cycle test. Watches the system through a complete run to catch anything the static checks miss.

You can see the full Commerce City AC maintenance service page for more detail on the cooling side. Fortunately, running through this checklist twice a year catches most issues before they become breakdowns on a 95-degree day.

The Heating Side: What Techs Check on Your Furnace

A fall furnace tune-up covers different territory because furnace failures are safety issues, not just comfort issues. Specifically, here’s what a real tech runs on the heating side:

Heat exchanger inspection. A cracked heat exchanger leaks carbon monoxide into your home. This is the single most important safety check on any furnace visit.
Burner cleaning and adjustment. Carbon and dust foul the burners over time, which hurts efficiency and combustion quality.
Ignitor and flame sensor testing. These are the two most common furnace failures. Catching a weak ignitor or dirty sensor at a tune-up prevents a no-heat call in January.
Gas pressure verification. Especially critical at Commerce City’s altitude, where thinner air changes how gas burns.
Flue and venting inspection. Confirms combustion gases exit the home safely.
Combustion analysis. Measures carbon monoxide levels in the flue to catch dangerous combustion before it hurts anyone.
Air filter replacement. Same story as the AC side: a dirty filter starves the system of airflow.
Blower motor inspection and lubrication. The same blower runs both heating and cooling, so this doubles up.
Electrical connections and safety switches. We verify these on every visit.
Thermostat calibration. Confirms accurate temperature control.
Full heat cycle test. Watches ignition, run, and shutdown from start to finish.

For more on the heating side, see our Commerce City furnace maintenance service page. In addition, because Commerce City sits at roughly 5,150 feet, your tech should be adjusting combustion for altitude on every visit. Unfortunately, techs who skip that step leave the furnace running rough, which shortens component life and drives higher repair costs down the line.

How Long Does an HVAC Tune-Up Take?

A real HVAC tune-up in Commerce City takes about 60 to 90 minutes per system. In other words, a full furnace or AC visit needs at least an hour of hands-on work to run the complete checklist. If you’re getting both systems tuned on the same visit, plan for two to three hours total.

However, be wary of any HVAC company promising to knock a “full tune-up” out in 20 or 30 minutes. In practice, that’s not a tune-up. Instead, it’s a quick visual walk-around that lets a technician find things to sell you. The actual work of cleaning coils, testing combustion, and measuring performance takes real time.

How Often Should You Get an HVAC Tune-Up?

You should get an HVAC tune-up twice a year in Commerce City: your AC in the spring before cooling season, and your furnace in the fall before heating season. Specifically, spring is the right time to catch AC issues before the first 90-degree day. Similarly, fall is the right time to catch furnace issues before the first hard freeze.

Twice a year matters more in Colorado than in most of the country. In fact, Commerce City’s altitude, dry air, and extreme temperature swings put more stress on HVAC equipment than mild coastal climates do. As a result, systems here wear faster and need more consistent maintenance to hit their expected lifespan.

Furthermore, most manufacturer warranties require documented annual maintenance to stay in force. Because of this, skipping tune-ups can void the warranty on your equipment right when you need it most. A written summary from every visit proves the warranty stays valid, which is one of the quieter benefits of a real service plan.

How Much Should an HVAC Tune-Up Cost in Commerce City?

An HVAC tune-up in Commerce City typically runs $75 to $150 per system for a real, thorough visit. In practice, that’s the honest going rate for the 60 to 90 minutes of hands-on work a proper tune-up requires. As a result, tuning both your furnace and AC out of pocket runs about $150 to $300 a year.

Additionally, most companies charge a trip or diagnostic fee on top of the tune-up, usually $75 to $150 per visit. However, most maintenance plan members skip that fee entirely.

Why the Cheap $49 Tune-Up Often Isn’t Worth It

You’ve probably seen ads for a $49 “HVAC tune-up special.” In most cases, those aren’t real tune-ups. Instead, they’re loss-leader visits that get a technician in the door so they can find things to sell you. As a result, what looks like a bargain on the front end often ends with a several-hundred-dollar upsell on the back end.

Here’s the honest math on why. In practice, a full 60 to 90-minute tune-up costs the company $75 to $125 in labor alone before parts, cleaning supplies, or truck costs. Therefore, a $49 ad price means the company is losing money on the visit. Unfortunately, they’re not doing it out of the goodness of their hearts. Rather, they’re expecting to make it back by finding a problem you didn’t know you had.

In contrast, a real HVAC tune-up is genuinely worth it every time. Consequently, a real tune-up prevents an expensive breakdown on the coldest night of the year, keeps your energy bills lower, extends equipment life, and holds your manufacturer warranty valid. On the other hand, a $49 walk-around does none of that. In short, a real tune-up is worth every dollar. Meanwhile, a loss-leader tune-up usually costs you more in the end.

The 360 HVAC Maintenance Plan: $189 a Year, No Surprises

The 360 HVAC Maintenance Plan covers everything a Commerce City homeowner needs to keep an HVAC system healthy, for a flat $189 a year. Specifically, here’s what’s included in the plan:

Two seasonal tune-ups. AC in the spring, furnace in the fall, both with the full checklist above.
Full safety inspection on every visit. Combustion checks, heat exchanger inspection, and carbon monoxide testing.
Written summary after every visit. A clear record of what we checked and found, which doubles as your warranty documentation.
Priority scheduling. Members go to the front of the line when everyone else is calling at once.
Member discount on repairs. You get a discount on any repair you need. In fact, one discounted repair can pay for the plan by itself.
24/7 emergency service. Included with the plan. Furnace out at midnight or AC dead in a heat wave? We answer.
Annual reminders. We track when your tune-ups are due and reach out. Nothing slips through the cracks.
No lock-in contracts or auto-renewal traps. Straightforward annual plan. We earn your renewal by being worth it.

The math on the plan is straightforward. In fact, two seasonal tune-ups alone cost about $150 to $300 out of pocket. Therefore, at $189, the plan effectively bundles the priority scheduling, repair discounts, and 24/7 emergency service for free. Furthermore, according to the ENERGY STAR HVAC maintenance checklist ↗, regular tune-ups are the single most cost-effective step homeowners can take to hold down long-term operating costs.

Above all, this is a real service plan from a local Commerce City owner. Because our technicians work without commission quotas, every tune-up visit is genuine hands-on maintenance. You get a real technician at your door, not a commissioned salesperson pitching a replacement you don’t need.
