Major Systems Overview: Understanding Your Air Conditioning System

A central air conditioning system is made up of multiple components, each of which plays a vital role in keeping your home cool and comfortable. Knowing how these systems work—and what can go wrong—can help you make informed decisions about repair or replacement.

Key Components of an AC System

• Evaporator Coil: Located inside your home, this coil absorbs heat from indoor air. If it’s dirty or frozen, your AC won’t cool properly.
• Condenser Coil: Located outside, it releases the heat from your home. Clogged or dirty coils cause the system to overheat and reduce efficiency.
• Compressor: This is the heart of the AC system. It circulates refrigerant between the indoor and outdoor coils. Compressor failure is often a costly repair.
• Refrigerant Lines: These lines carry refrigerant between the evaporator and condenser coils. Leaks in these lines can reduce system performance and pose environmental risks.
• Thermostat: The command center of your system. A malfunctioning thermostat can cause short cycling, uneven cooling, or complete shutdowns.
• Air Handler and Blower: This component pushes the cooled air through your home’s ductwork. Faulty blowers can result in poor airflow.

Common Problems by Component

• Dirty Filters and Coils: Restrict airflow, decrease efficiency, and increase wear on parts.
• Low Refrigerant: Causes the system to run constantly with poor cooling output.
• Electrical Issues: Faulty wiring or capacitor problems can prevent the system from turning on or damage critical components.
• Clogged Drain Lines: Lead to water leaks, moisture buildup, and potential mold issues.
• Ductwork Leaks: Allow conditioned air to escape before reaching your living spaces.

Signs You Need a Professional Assessment

• Your system is more than 10–15 years old
• You’re facing repeated repairs or rising energy costs
• There’s little to no airflow from the vents
• You notice foul odors when the AC runs
• Your thermostat settings no longer seem to control indoor temperature

Dalton’s technicians use advanced diagnostic tools to assess system performance and pinpoint inefficiencies or mechanical issues. If repairs aren’t cost-effective, we’ll walk you through energy-efficient replacement options that match your home’s needs and your budget.

Efficiency and Compliance With SEER2 Standards

In Iowa, new AC systems must meet or exceed a SEER2 rating of 14.3. At Dalton, we install only the most efficient systems from trusted brands to ensure your home stays cool while keeping energy costs in check. If your current system is outdated, now may be the perfect time to upgrade.

AC Installation & Replacement

Before the Iowa heat reaches its peak, your AC system should be ready to perform efficiently. If your current unit is underperforming or you’re planning a new construction, a professional installation or system replacement ensures reliable and lasting comfort.

When to Consider:

• Your system is more than 10 to 15 years old, making it more prone to breakdowns and less likely to meet current efficiency standards.
• You find yourself scheduling frequent and increasingly expensive repairs, indicating widespread wear and aging components.
• The unit no longer meets the SEER2 energy efficiency requirement (14.3 in Iowa), resulting in higher energy bills.
• Your AC was improperly sized for your home's square footage, causing it to short-cycle or operate continuously.
• Some rooms remain too hot while others are overly cool, revealing poor system balance and airflow inefficiencies.

Why It’s Important:

Installing the right system is crucial for long-term efficiency, comfort, and cost savings. A properly sized, professionally installed system prevents premature wear, improves humidity control, and ensures even cooling throughout your home.

What’s Included:

• A detailed in-home assessment to calculate the ideal system size based on your home’s layout and cooling needs
• Expert recommendations on units that meet or exceed Iowa’s SEER2 energy efficiency standards (14.3 or higher)
• Safe removal and proper disposal of your old air conditioning system
• Installation of top-tier, energy-efficient brands designed to meet your comfort and performance expectations
• Smart thermostat installation and integration for advanced climate control and automation

AC Repairs

Even the most reliable systems can experience wear and tear. When they do, Dalton’s expert team is available 24/7 to restore your comfort quickly and effectively.

When to Consider:

• Strange sounds such as rattling, buzzing, or squealing suggest mechanical or electrical problems.
• Moisture or puddles around your system may be caused by a blocked drain line or refrigerant leak.
• Frequent cycling or an unresponsive system often indicates thermostat or electrical control issues.
• Uneven airflow or persistent hot spots may be due to ductwork problems or blower motor failure.

Why It’s Important:

Timely repairs prevent further damage, enhance energy efficiency, and extend the system’s lifespan. Addressing small issues early reduces the risk of costly emergency repairs or full system failure.

What’s Included:

• Complete diagnostic inspection to pinpoint the issue
