What are the most common AC problems that require repair?

Common AC repairs include refrigerant leaks, frozen coils, clogged drain lines, capacitor or contactor failures, thermostat issues, dirty coils or filters, blower problems, and electrical faults that prevent proper cooling.

How can I tell if my AC needs repairs or a full replacement?

Repairs are often best for newer systems with isolated issues. Replacement may make more sense when the unit is older, needs frequent repairs, struggles to cool consistently, or would require a major component replacement.

Why does my AC keep freezing up?

AC freezing is commonly caused by restricted airflow (dirty filter, blocked vents, blower issues) or low refrigerant. Turning the system off to thaw and scheduling a professional inspection is recommended to prevent compressor damage.

What should I do if my AC won’t turn on?

Check the thermostat settings, replace thermostat batteries if applicable, verify the breaker isn’t tripped, and confirm the disconnect switch is on. If it still won’t start, the issue may involve electrical components that require a technician.

Why is my AC running but not cooling my home?

This can happen due to low refrigerant, dirty condenser coils, a failing compressor, blocked airflow, or thermostat problems. A professional diagnostic can identify the root cause and restore proper cooling.

Can running my AC with a dirty filter cause damage?

Yes. A dirty filter restricts airflow, which can strain the system, reduce efficiency, and contribute to coil icing or overheating. Replacing filters regularly helps protect performance and reduce repair risk.

What causes strange noises coming from my AC?

Banging, grinding, squealing, or rattling sounds may indicate loose parts, motor or fan issues, worn belts, or debris in the unit. Unusual noises should be checked promptly to avoid more extensive damage.

How long does an AC repair usually take?

Many AC repairs can be completed the same day, depending on the issue and part availability. After diagnosis, your technician can provide a clearer timeframe based on the repair needed.

How Do I Know If It’s Time to Replace My AC?

If your air conditioner is over 15 years old, frequently breaks down, or struggles to keep your home cool, it may be time for a replacement. Rising energy bills and costly repairs are also signs that an upgrade could be more cost-effective. A new, energy-efficient system can improve comfort while reducing long-term expenses.

What Factors Should I Consider When Choosing a New AC System?

The size of your home, energy efficiency ratings, and your budget all play a role in selecting the right air conditioner. A properly sized unit ensures optimal performance without excessive energy use. Consulting with a professional helps you choose a system that meets your cooling needs while maximizing efficiency.

How Long Does It Take to Install a New Air Conditioner?

Most AC installations can be completed in one day, though more complex projects may take longer. Factors like ductwork modifications, system type, and home size can affect the installation timeline. A professional technician will provide an accurate estimate based on your specific needs.

Will a New AC System Lower My Energy Bills?

Yes, modern air conditioning systems are designed to be more energy-efficient than older models. Features like variable-speed compressors, smart thermostats, and high SEER ratings help reduce energy consumption. A properly installed system can provide better cooling while lowering monthly utility costs.

Can I Install a New AC System Myself?

Installing an air conditioner requires specialized knowledge, tools, and expertise to ensure proper performance and efficiency. DIY installation can lead to improper sizing, refrigerant issues, and even system damage. Hiring a professional guarantees a safe, code-compliant installation that maximizes the lifespan of your unit.

What Is a SEER Rating and Why Does It Matter?

SEER (Seasonal Energy Efficiency Ratio) measures an air conditioner’s cooling efficiency. A higher SEER rating means greater energy savings and better performance, especially in warmer climates. Choosing a unit with a high SEER rating can help reduce your cooling costs over time.

Do I Need to Replace My Ductwork When Installing a New AC?

If your ductwork is old, leaking, or improperly sized, replacing or repairing it may be necessary to ensure maximum efficiency. Poor ductwork can lead to uneven cooling, higher energy bills, and added strain on your AC unit. A professional evaluation can determine if your ducts need modifications during installation.

What Maintenance Does a New AC System Require?

Regular maintenance, such as changing air filters, cleaning coils, and scheduling professional tune-ups, helps keep your AC running efficiently. Annual inspections ensure all components are working properly and prevent potential breakdowns. Proper maintenance extends the lifespan of your system and keeps energy costs low.

Roy's came out to do our heating and cooling yearly service. The technician found a crake in the heat exchange and it needed to be fixed or replaced on a 13 year old furnace. Matt suggested a new system. He called the office and a salesman, Robert Nolan came out and explained multiple options we had. We decided on a new furnace and airconditioner. We decided on option 2 he showed us. Because of our schedule the new system could not be installed for 3 days and Robert left us a stand alone heater if we needed it. The installers arrived on time and installed both systems by the end of the day. They put down covering in our hall and on the stairs down to the cellar. They cleaned up everything before they left and explained how to do a monthly cleaning of the furnace and how the new thermostat worked prior to leaving. We wouldn't have any other company but Roy's take care of our heating/cooling/electric & plumbing. They are wonderful!

Professional experience from original call, to first appointment, assessment of my issue, and strategizing ALL my options. They took a stressful situation and immediately de-escalated my stress level and walked me through each of their recommendations. On the day the job was to be executed I experienced a thorough and efficient crew that made me confident they knew exactly what they were doing. There were multiple guys at my job and I wish I could remember everyone’s name because they were all great. I will highlight that my Sr. Plumbing Tech Dan Stewart and his Tech Tony Robinson were amazing to work with. Prior to being introduced to Roy’s Plumbing I was a customer of another operation for 25 years. Needless to say I do not know what I was missing and will be switching to Roy’s for all my future needs.
