Air Conditioning Repair Castle Rock

Our Castle Rock HVAC technicians offer reliable and affordable air conditioning repairs, installation, and maintenance to keep your home cool and comfortable throughout the summer.

Does your air conditioning seem to struggle to keep your home cool? Is it making strange noises or refusing to turn on at all? Our AC repair experts will get to the bottom of the problem by diagnosing and fixing your air conditioning issues. Your AC repair cost will be prepared ahead of time and in writing so you will know exactly what to expect.

Common air conditioner problems we frequently encounter include:

  • Refrigerant leaks. Always allow a trained HVAC technician to fix a leak and test the repair to avoid damage to your air conditioning system.
  • Improper maintenance. Inadequate maintenance of an AC system can cause damage to the system itself, shorten the air conditioner's lifespan, and increase your energy costs.
  • Electric control failure when the fan and compressor controls wear out. This is often due to corrosion.
  • Sensor issues. The thermostat sensor measures the temperature of air entering the evaporative coil. If the sensor is not working correctly, the system may cycle constantly or fail to operate properly.
  • Drainage issues. A clog in the condensate drain can cause drainage issues that impact the performance of the air conditioner and may lead to mold and water damage.

Air Conditioner Maintenance Castle Rock, Colorado

HVAC maintenance is the easiest and most cost-effective strategy for extending the life of your air conditioner and reducing energy costs. It's important to have your AC inspected and maintained ahead of summer to avoid unpleasant surprises or repair bills down the road. Our Castle Rock AC maintenance experts will perform a comprehensive 22-point inspection. We offer the lowest AC maintenance prices in the Castle Rock area!

Replacing Your Castle Rock Home AC System

A central air conditioner can last for 15-20 years, if properly maintained. Still, an air conditioner that is nearing the end of its life will likely require more frequent repairs and operate less efficiently than a new system. It may be time to replace your air conditioning system if it is more than ten years old, operates very loudly, you have had several repairs in the last couple of years, or your home has humidity or dust issues. Our professional Castle Rock air conditioner installation can save you up to 20% on your energy costs!

Household Heating Services for Castle Rock, CO

Don't get caught in the cold with a boiler or furnace that's preparing to fail. Our affordable heating services will ensure your home stays toasty warm during the long Colorado winters.

Furnace Repair Castle Rock

While furnaces can last for 10-15 years, repairs are occasionally necessary to ensure the system performs optimally. Common furnace repairs involve worn motor belts, bad thermocouples, motor failure, and failed thermostats. If your furnace is failing to keep your home warm, or it's nearing the end of its life, making loud noises, or you notice climbing heating costs, our furnace technicians will get to the bottom of the problem. If a cost-effective repair is not possible, we may recommend replacing your furnace with a new energy-efficient model.

Boiler Repair, Installation or Replacement

A boiler can last for about 12 years on average before it requires replacement. Sometimes simple repairs can restore function to your boiler if the problem is a blockage, pressure loss, a failed thermostat, or pump failure. Your boiler may be preparing to fail if you notice rooms that are too cold or too hot or it's more than 10 years old. If cost-effective repairs are not possible, our Castle Rock boiler technicians will help you select a replacement boiler that fits your budget and heating needs.
