Preventive HVAC Maintenance in North Little Rock, AR

What Happens to an Unmaintained HVAC System in the Arkansas Climate

Central Arkansas subjects HVAC equipment to conditions that most of the country doesn’t experience. Your air conditioner may run at near-full capacity for four to five months straight. Humidity levels that routinely exceed 70% create ideal conditions for mold and mildew growth in drain lines and coil surfaces. Summer pollen loads your filter faster than any other region in the country.

Meanwhile, the furnace or heat pump that sat idle all summer may have developed a cracked heat exchanger, a failed capacitor, corroded electrical contacts, or a clogged burner assembly, none of which you’ll know about until the first cold night of October.

What a missed maintenance cycle costs in real terms:

• Capacitor failure (commonly caught in maintenance): $85–$200 repair
• Frozen coil from dirty evaporator (preventable with coil cleaning): $150–$400 repair + possible lost refrigerant
• Condensate line blockage (cleared in every maintenance visit): $75–$250 service call
• Compressor failure from prolonged high-strain operation: $1,200–$2,800
• Heat exchanger crack (caught in fall inspection = inexpensive repair; missed = potential CO risk): $800–$1,600

Bi-annual maintenance from Infinity Services: $89–$149 per visit.

The math is not close

What Our Maintenance Visit Actually Covers

We do not offer a 15-minute “inspection” that checks visible parts and finds nothing. A maintenance visit from Infinity Services is a full technical evaluation of your system, the parts you can see and the parts that determine whether it keeps running.

Cooling System — Spring Maintenance Visit

• Clean evaporator and condenser coils (dirty coils reduce efficiency by 20–40%)
• Check refrigerant pressure and inspect for leaks
• Test starting and run capacitors
• Inspect and test contactors and electrical connections
• Clear condensate drain line and check the pan for algae growth
• Inspect and lubricate blower motor and fan components
• Test thermostat accuracy and calibration
• Replace air filter
• Record operating measurements: suction and discharge pressure, delta-T, amp draws

Heating System — Fall Maintenance Visit

• Inspect heat exchanger for stress cracks — a cracked exchanger is a carbon monoxide risk
• Test and clean burners, verify ignition sequence (gas furnace)
• Check reversing valve and defrost cycle (heat pump)
• Test flame sensor and pressure switches
• Inspect flue pipe and venting for blockage, rust, or separation
• Check electrical components and tighten connections
• Test thermostat in heat mode
• Replace air filter

Written Condition Report — Included Every Visit Every maintenance visit ends with a written summary: what we found, what we cleaned or adjusted, and anything worth monitoring. You’ll have a paper record of your system’s condition, useful for warranty claims, home sale disclosures, and tracking how the system changes year over year.

Spring vs. Fall — Why Both Visits Actually Matter

Some companies offer an annual maintenance plan and make it sound like one visit covers everything. It doesn’t.

The spring visit prepares your cooling system to handle an Arkansas summer. We find issues before the season loads the system, not after a July breakdown when every HVAC company in Pulaski County has a two-week wait.

The fall visit prepares your heating system for winter. Furnaces and heat pumps that sat dormant for months need to be verified before you depend on them. This visit also catches the heat exchanger issues that create carbon monoxide risk, something that genuinely doesn’t show up without this inspection.

Book your spring visit in March or April. Book your fall visit in September. Both slots fill before the season peak every year.

How Much Does HVAC Maintenance Cost in North Little Rock?

Standard residential maintenance visit: $89–$149 per visit depending on system type and complexity.

Bi-annual visits (both spring and fall): $175–$300 annually for most single-system homes.

If you have multiple systems or a combined heat pump and supplemental unit, we’ll quote accordingly.

Pricing is confirmed before the visit. There are no diagnostic fees charged on top of the maintenance visit rate.

Maintenance Plans — If You’d Rather Not Think About It

If managing appointment timing isn’t something you want to track, ask about our maintenance plan options when you call. Plan members get priority scheduling, helpful during spring and fall demand peaks when appointment availability gets tight.

Frequently Asked Questions

How often should HVAC be serviced in Central Arkansas?

Twice per year is the correct answer for this climate — not once. Spring before cooling season, fall before heating season. The conditions here are harder on equipment than most regions. Annual-only maintenance means you’re going into every other season with an uninspected system.

Can you maintain a system you didn’t install?

Yes. We service all major brands regardless of who installed them. Carrier, Trane, Lennox, Rheem, Goodman — bring us whatever you have.

What if you find something wrong?

We tell you what we found, explain what it means in plain terms, and give you repair options with pricing before we touch anything. You decide. No automatic repairs added to your invoice without your approval.

Will maintenance actually extend my system’s life?

Yes, documented across the industry. Properly maintained residential HVAC systems typically last 15–20 years. Unmaintained systems often fail at 10–12 years in demanding climates like Central Arkansas. The difference in equipment cost alone — not counting the repairs along the way — is $8,000–$15,000. Two visits a year is not a hard investment to justify.

Do you offer service contracts or maintenance agreements?

Yes. Ask about current options when you call — we’ll walk you through what’s available
