Common Issues

Common Air Conditioning Problems We Repair

Understanding what can go wrong with air conditioning systems helps you recognize when professional repair is needed. Based on our 8 years of field experience in Altoona, these are the most common AC problems we encounter:

ac_unit

Refrigerant Leaks

Refrigerant doesn't get "used up" during normal operation—if your system is low on refrigerant, there's a leak somewhere. Symptoms include inadequate cooling, ice formation on indoor coils, and systems that run constantly without reaching the desired temperature.

We locate leaks using electronic leak detectors, pressure testing, and UV dye methods. Once found, we properly repair the leak and recharge the system to manufacturer specifications.

settings

Compressor Failure

The compressor is your AC system's heart, circulating refrigerant through the system. Warning signs include loud noises from the outdoor unit, hard starting or tripping breakers, and complete system shutdown.

We diagnose the root cause to prevent repeat failures. Depending on system age and warranty coverage, we'll recommend repair or replacement based on what makes most economic sense.

severe_cold

Frozen Evaporator Coils

Ice forming on your indoor coil indicates restricted airflow or refrigerant problems. Common causes include dirty air filters, blocked return air vents, failed blower motors, low refrigerant levels, or dirty evaporator coils.

We identify why ice formed and address that root cause—whether it's improving airflow, fixing refrigerant leaks, or resolving equipment failures.

electric_bolt

Electrical Component Failures

Air conditioners rely on numerous electrical components: capacitors that start motors, contactors that control power flow, relays that activate components, and control boards that orchestrate operation.

We test capacitors, contactors, relays, and control boards to identify failed components and replace them with quality parts rated for your specific equipment.

air

Blower Motor Problems

The blower motor circulates air across your evaporator coil and through your home's ductwork. Motor bearings wear out over time, causing squealing or grinding noises. Failed motors stop airflow completely.

We evaluate whether motors need lubrication, bearing replacement, or complete motor replacement with accurate diagnosis before recommending motor replacement.

water_drop

Condensate Drain Clogs

Air conditioning removes humidity from indoor air, producing condensate that must drain away. When drain lines clog with algae, mold, or debris, water backs up and can trigger safety switches that shut down your system.

We clear blockages, treat drain lines to prevent biological growth, verify proper drain pitch, and test safety switches.

thermostat

Thermostat Malfunctions

Sometimes the problem isn't with your air conditioner at all—it's with the thermostat controlling it. Failed sensors, dead batteries, incorrect settings, or communication problems can all prevent proper operation.

We test thermostat operation, verify proper wiring, check calibration accuracy, and confirm communication with your AC system.

filter_alt

Dirty or Restricted Airflow

Reduced airflow from dirty filters, closed vents, blocked registers, or dirty coils forces your system to work harder while delivering less cooling. The system may run constantly, freeze up, or fail to maintain comfortable temperatures.

We measure airflow, inspect for restrictions, clean dirty components, and ensure your system moves the proper volume of air.

Important Decision

When to Repair vs. Replace Your Air Conditioner

One of the most common questions we hear is whether to repair an aging system or replace it entirely. This decision involves several factors including system age, repair costs, current efficiency, and overall reliability.

Age-Based Guidelines

  • Years 1-7: Prime performance - Repair almost always makes sense
  • Years 8-12: Middle age - Repair usually makes economic sense
  • Years 13-15: Senior status - Consider both repair costs and remaining lifespan
  • Years 16-20: Extended life - Major repairs warrant serious replacement consideration
  • Beyond 20 Years: Borrowed time - Replacement usually makes more sense

Efficiency Considerations

Older systems operate less efficiently than modern equipment. For systems requiring major repairs, calculating potential energy savings from new equipment helps inform the repair versus replacement decision.

  • trending_down

    10-Year-Old Systems typically operate at 10-12 SEER, while new systems achieve 14-18 SEER2

  • savings

    Energy Cost Impact - Upgrading from 10 SEER to 16 SEER2 can reduce cooling costs by 35-40%

  • calculate

    Payback Calculations - Higher efficiency means lower operating costs that offset replacement investment over time

  • eco

    Environmental Benefits - Modern refrigerants and efficiency improvements reduce environmental impact

Our Honest Recommendation Approach

At Keystone Heating and Air, we provide honest guidance based on your specific situation. When repair makes sense, we execute it properly to maximize your system's remaining life. When replacement is the better choice, we offer professional installation.

FAQs

Frequently Asked Questions About AC Repair

First, check some basics before calling for service: verify your thermostat is set to cooling mode with temperature below current indoor temperature, check that the circuit breaker hasn't tripped, ensure the outdoor disconnect switch is on, and confirm you have a clean air filter. If these check out but your system still doesn't work, contact Keystone Heating and Air at 814-515-6715. Based on our experience, about 20% of "broken" air conditioners just need a reset breaker or thermostat adjustment, but the other 80% require professional diagnosis and repair.

We understand that air conditioning failures during hot weather create urgent situations requiring prompt response. For emergency situations, we typically provide same-day or next-day service depending on call volume and time of day you contact us. Our 8 years of experience serving Altoona, PA have taught us the importance of responsive service when families are suffering without cooling. Call 814-515-6715 immediately when your AC fails—we'll get you on the schedule as quickly as possible.

Repair costs vary based on what's wrong with your system, which components need attention, and how extensive the repair work is. After diagnosing the issue, we provide a clear, detailed estimate before any work begins so you can make informed decisions. We never perform unexpected repairs without your approval. Call us for accurate pricing based on your specific repair needs.

Yes, our technicians service all brands and models of residential air conditioning systems. While we specialize in Armstrong equipment that we install, we regularly repair Carrier, Trane, Lennox, Goodman, Rheem, York, Amana, and all other major brands. Our broad experience across multiple manufacturers means we understand the specific characteristics and common issues of different equipment brands. Whatever brand you own, we have the knowledge to diagnose and repair it properly.

This decision depends on several factors including system age, repair needs, current efficiency, and overall reliability. As a general guideline, if your system is under 10 years old and the required repair is minor to moderate, repair often makes sense. For systems 12-15 years old that need major component repairs, replacement may provide better long-term value through improved efficiency and reliability. Systems beyond 15 years approaching significant repair needs should strongly consider replacement. We'll provide an honest assessment of whether repair or replacement makes the most sense for your specific situation based on age, condition, performance, and long-term value.

Frozen evaporator coils indicate either restricted airflow or refrigerant problems. Common causes include dirty air filters (most common), blocked return air vents, failed blower motors, dirty evaporator coils, low refrigerant from leaks, or malfunctioning expansion valves. The ice must completely melt before we can properly diagnose the root cause. Based on our experience in Altoona, we've found that about 60% of freezing problems relate to airflow restrictions that homeowners can prevent with regular filter changes, while 40% involve refrigerant or mechanical issues requiring professional repair.

Compressor failures often result from other underlying problems rather than simple compressor defects. Common causes include running with low refrigerant charge (from leaks), electrical problems causing hard starting, dirty coils forcing the compressor to work harder, inadequate maintenance leading to system contamination, or operating with restricted airflow. Sometimes compressors fail from age and normal wear after years of service. When we diagnose compressor problems, we always investigate what caused the failure to prevent repeat problems if you choose to replace the compressor.

Yes, we repair refrigerant leaks when we can locate and access them. Small leaks in refrigerant lines, joints, or coils can often be repaired by brazing the leak point and properly recharging the system. However, some leaks occur in locations that are difficult or impossible to access economically, or involve coil tube failures that are expensive to repair. We use electronic leak detection, pressure testing, and UV dye methods to locate leaks accurately. Once found, we'll explain repair options and costs so you can make informed decisions about proceeding with leak repair.

We recommend professional air conditioning maintenance annually, ideally in spring before cooling season begins. Annual service allows us to clean components, verify refrigerant charge, test electrical components, optimize airflow, and identify potential problems before they cause mid-season failures. Our experience shows that systems receiving annual maintenance experience 50-70% fewer breakdowns than neglected equipment and typically last 5-7 years longer. Between professional service, homeowners should check filters monthly and keep outdoor units clear of debris. Visit our AC maintenance page for detailed information.

Several factors can cause high cooling costs: systems low on refrigerant work harder and run longer, dirty coils reduce heat transfer efficiency forcing longer run times, aging equipment naturally becomes less efficient over time, improperly sized systems cycle inefficiently, dirty filters restrict airflow requiring more energy, duct leaks waste cooled air, and poor home insulation increases cooling loads. We can evaluate your system's efficiency, identify problems contributing to high operating costs, and recommend solutions. Sometimes simple repairs restore efficiency, while other situations benefit from upgrading to more efficient equipment.

Different noises indicate different problems: grinding or squealing from the indoor unit usually means blower motor bearing problems, clicking from the outdoor unit might indicate relay or contactor issues, hissing could suggest refrigerant leaks, rattling often means loose panels or failing fan motors, buzzing may indicate electrical problems, and banging or clunking can signal serious compressor or fan blade issues. Any unusual noise warrants professional evaluation—operating equipment with abnormal sounds often causes additional damage. Call 814-515-6715 for diagnostic service when you notice unusual AC noises.

Yes, we stand behind our repair work with workmanship guarantees. The specific guarantee period depends on the type of repair performed and parts installed. Manufacturer warranties cover the replacement parts we install according to their warranty terms. We want you completely satisfied with our service and will address any concerns related to our repair work. Our reputation in Altoona, PA depends on quality repairs that last, which is why we focus on proper diagnosis and quality workmanship on every repair job.

While no maintenance program prevents all possible failures, regular professional maintenance dramatically reduces breakdown frequency. Our experience shows that well-maintained systems experience 50-70% fewer mid-season failures than neglected equipment. Simple homeowner maintenance like monthly filter changes prevents many common problems. Professional annual service addresses wear before components fail and identifies developing issues early. While aging systems eventually need repairs despite excellent maintenance, consistent care minimizes problems and extends equipment life significantly.
