At Guthrie & Sons, our heat pump services in Rancho Santa Fe make it easy to install and care for these amazing systems.

Frequently Asked Questions
How do inverter heat pumps work?
Inverter heat pumps adjust their speed automatically to match your heating or cooling needs. That means steadier temperatures, lower energy use, and quieter operation compared to traditional systems.
How do I select the right HVAC system for my home?
We look at your home’s size, layout, insulation, and how you use each space. Then, we walk you through the best HVAC options, from heat pumps to central heating and cooling systems.
Does my home need a humidifier or dehumidifier?
In Rancho Santa Fe, the coastal air can lead to excess indoor moisture—especially in well-sealed or shaded homes. A whole-home dehumidifier helps prevent musty odors, mold growth, and that sticky, uncomfortable feeling. We’ll help you decide if it’s the right fit for your space.
What signs indicate my air conditioner needs repairs?
Watch for weak airflow, unusual noises, warm air, or higher energy bills. These are all signs your AC might need repairs—and we’re happy to take a look and get it sorted quickly.
Is maintenance required for warranty compliance?
Yes. Most heating and cooling system warranties require proof of routine maintenance. We handle that for you with reminders, records, and tune-ups that keep your system protected.
