Furnace Services in North County, CA

Servicing Gas, Oil & Electric Furnaces in Carlsbad, Vista, San Marcos & the Surrounding Areas

Furnaces are the most common heating systems in the country. Also called forced-air systems, furnaces use natural gas, oil, or electricity to produce heat, which is then distributed via a duct system. Although a highly reliable heating system, this type of heater also experiences problems such as dirty filters, cracked heat exchanger, or issues with the pilot light or ignition that can eventually cause the equipment to perform poorly or eventually shut down. When any of these happen, remember to call Sherlock Plumbing, Heating & Air. We provide fast, reliable furnace services in Carlsbad and the surrounding areas of North County. With a team of licensed and certified technicians, we can handle any issues, regardless if you have gas, oil, or electric furnace.

Repair vs. Replacement

Our clients trust us to always get their heaters back on track whenever there’s a problem with the system. Furnace repairs are usually the most economical way to make sure you have reliable heat all winter long. However, if you are needing repairs frequently, such as two or three times a year, a replacement may be a more practical solution.

Below is a checklist to help you determine if you should replace your furnace:

  • The furnace is more than 15 years old
  • The furnace takes a longer time to reach the thermostat temperature
  • The rooms throughout your home have different temperatures
  • Your heating bills are continuously increasing
  • The furnace operates louder than usual

When it’s time for a furnace replacement, you can count on our expertise to help you select a new system that is energy-efficient and of high quality. We also provide a flawless installation every time, ensuring your complete satisfaction. We also have financing options available, since we know not everyone is prepared for this kind of expense.
