Why Heat Pumps Make Sense for Many Bay Area Homes

The Bay Area’s microclimates are ideal for a heat pump. According to the U.S. Department of Energy, heat pumps can deliver two to four times more heating energy than the electrical energy they consume because they transfer heat rather than generate it directly.
You also benefit from a single unit that provides heating and cooling – one unit to service and keep running. California also provides rebates and tax credits, which may or may not be applicable in your situation. With ductless options, even historic homes can stay comfortable.

Heat Pump Installation

Your home or business demands will vary based on size and how many levels you have. Our heat pump installation service starts with a site visit to examine your space’s current setup, size, ductwork, and system requirements. We’ll then file permits (where necessary), install the unit, and run tests to verify that it’s working properly.

Heat Pump Repair, Maintenance, and Replacement

Your heating and cooling system will run for 10 – 15+ years with the right care. We offer
heat pump repair that replaces worn parts with new ones that come with a warranty. If your unit is failing, we may recommend heat pump replacement based on our output calculations. We will even provide multiple options to choose from. Units that are still in good shape require maintenance. We’ll perform routine maintenance to maximize performance.

Ductwork, Thermostats, and Indoor Air Quality
Residential and commercial HVAC systems have multiple components that keep them running well. Our technicians know that indoor air quality relies on the following:
Ductwork and Airflow Support

Air flows through your home’s ducts and into each room. Our ductwork services seal your system, provide airflow balance and include repairs to eliminate cold or hot spots. If pressure issues exist, we’ll rectify them to prevent further strain on your system. Owners see a noticeable increase in comfort after we perform these services.

Thermostat and Smart Thermostat Installation

Turn your heat up or down in seconds with a smart thermostat. Whether you’re across the world or down the street, open your thermostat app and adjust the heating and cooling in your space. Faulty units lead to inaccurate indoor temperatures and may make you increase demand on your unit unnecessarily.

Indoor Air Quality Solutions

According to the U.S. Environmental Protection Agency (EPA), Americans spend approximately 90% of their time indoors, where some pollutant concentrations may be 2–5 times higher than typical outdoor levels. Improving indoor air quality can support comfort and overall well-being. Whether it’s old ductwork replacement in Belmont, CA, or an air quality test, our team can perform them for you. We’ll take corrective action based on our findings to ensure your air quality is healthy for your family or customers.

Choosing the Right HVAC System for Your Home
At Freon Service, we know that proper heating and cooling require more than picking the newest system on the market. Our technicians offer system sizing and load calculation to verify that the unit you choose offers the power your home needs for even air temperatures throughout.
Whether you request an HVAC or AC replacement, we recommend you choose a system based on:
- Match equipment to your regional climate requirements
- Traditional split or ductless systems, based on your current setup
- Heating and cooling requirements based on manual J load calculations
- Determine the efficiency rating based on AFUE and SEER2 ratings
Our team will work alongside you to select the right HVAC system for your needs. We may be able to help you find rebates and financing options, when available, that will help you make your new heating and cooling system more affordable.
