"I had trouble with the AC about a month after they did an annual service and replaced the capacitor. The system locked up and they came out and I watched as they pulled an obviously old, worn, and burnt, electrical part out next. They replaced that part for the cost of the part and waived the labor as it was so close to the last service. The system is old and they were finding parts that were reaching the end of their life and replacing rather than trying to sell me a whole new system but let me know they would be there if I decided I needed a new system. Fast service, pleasant and knowledgeable personnel."

"Bobby came out and installed a complete Trane system and even relocated the furnace and A/C compressor to a more sensible location. The installation crew was polite, professional and efficient. The new heating and air system works flawlessly. Best service I have ever gotten from a HVAC company ever!"

Heating and Air Conditioning FAQs, answered by experts

There are a few things you can do to make your AC repair technician’s job easier and your home more comfortable while you wait for AC repair:

  • Cut back trees, shrubs, and weeds around the outdoor compressor 

  • Clear a pathway inside and outside to your AC components

  • Set up a ladder for attic access if necessary

  • Pull your window AC out of the window and place in an easily accessible spot

  • Supplement with fans and open windows to help keep your house comfortable

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

Troubleshooting common issues with your AC often sheds light on a problem with the compressor. Signs that you need to replace a bad compressor include your AC blowing warm air, short cycling (turning on and off), making strange noises, and blowing less air overall. Since these problems can stem from several areas of your AC, always call a local AC repair team to confirm it's the compressor.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.
