Top-Rated Heating Tune-Ups

As a heating system ages, its effectiveness is usually impacted by regular wear and tear. Guthrie & Sons provides comprehensive heating services for split systems, heat pumps, packaged units, and ductless mini-splits. When paired with expert installation, heating maintenance prolongs the lifespan of your home’s heating.

During a heating maintenance service, you can expect us to:

  • Test the thermostat and its control settings

Benefits of Heating Maintenance

Maintenance plays a vital role in the overall function of a home heating system. By scheduling an annual tune-up, homeowners can enjoy benefits like:

  • Lower heating costs: Regular maintenance ensures your system is at its most efficient, reducing energy consumption.
  • Improved indoor air quality: Clean air filters in heat pumps promote better ventilation and a dust-free environment.
  • Fewer repairs: Identifying potential issues early helps prevent costly breakdowns.
  • A longer-lasting unit: Thorough maintenance can add years to your ductless mini-split, heat pump, or packaged unit.
  • Greater peace of mind: No matter how cold it gets outside, you’ll know your heating system is up to the task.

Signs You Need a Heating Tune-up

Even though San Diego enjoys a mild winter, temperatures can still drop below a comfortable degree, especially at night. If you’re noticing any of these heating issues, consider scheduling a tune-up:

  • Higher-than-average bills: Unexplained spikes in utility bills often signal an inefficient or malfunctioning HVAC system.
  • Inconsistent or uneven heating: Be aware of cool drafts or concentrated areas of warmth.
  • Musty odors: Clogged drain lines in heat pumps can trap moisture, leading to mold growth or musty smells.
  • Strange noises: Rattling, grinding, or squealing sounds aren’t normal — they point to issues with a blower fan, compressor, or motor.

Heating Maintenance FAQs

How often should I schedule heating maintenance in San Diego?

We recommend scheduling heating maintenance at least once a year. An annual tune-up will significantly improve the efficiency of your home’s temperature control.

Scheduling a service in the fall ensures that your heating system will be working at its best right before the coldest months.

Change or clean your air filters regularly and ensure there are no blockages around vents or registers. For heat pumps, make sure the outdoor unit is free from debris like leaves or dirt.

Heat pumps typically last 10 to 15 years with proper maintenance. If you have an older unit that requires frequent repairs, it may be time to consider replacement.

Great experience from my first inquiry setting up a consult, the actual consult, install, and completion. I am completely satisfied with the work performed. I had my 45 year old furnace replaced and AC installed. I will continue to be a G&S customer in the years to come due to the professionalism, customer service, and genuine warmth I experienced. Thank you so much for making the whole process seamless!

Vlad is very easy to work with as he is very straight forward. He worked with me a little on the final quote which I appreciated and seems to understand the space saving features I required. The work still needs to be done and the condo approval process needs to begin but I feel very comfortable.

he double checked everything and discovered that the recent tenting closed the vent on the roof which he then fixed. He is one of the very few service guys who actually services a product w/o trying to sell you something. good man.

Really appreciate our 2 technicians from Guthrie & Sons, Air and Solar! My parents have been served by the company for over 20 years and Guthrie continue to impress with their outstanding understandings of our HVAC system and ability to refresh, repair or replace items to keep system in top shape even though its an older system. Their service contracts are reasonably priced and I know we will get excellent value for the cost. Thank you!

Having trouble with the remote and to operate our mini split cassette unit. Within 5min Mario had the unit up and running as well as how the unit with remote works efficiently. Mario also went to bat for us to have the condenser mounted on the Guest House rather than in the dirt inches away from our brow ditch.Thanks Mario
