HVAC Maintenance & Tune-Up Services in Hayward & The Bay Area
Airstars HVAC offers comprehensive HVAC maintenance and tune-up services for homeowners in Hayward, Fremont, Union City, and the surrounding East Bay.
Your heating and cooling system is likely the most expensive appliance in your home. Just like your car needs regular oil changes to run smoothly, your HVAC system requires annual maintenance to perform at its best.
Neglecting your system leads to efficiency loss, higher PG&E bills, and premature failure. At Airstars, our Precision Tune-Ups are designed to catch small problems before they turn into expensive emergency repairs.
Why Is Maintenance Essential?
According to Energy Star, proper maintenance is the most effective way to ensure your system runs efficiently.
1. Lower Energy Bills
A dirty or neglected system has to work harder to heat or cool your home. For example, a refrigerant undercharge of just 10% can increase operating costs by 20%. Regular tuning restores efficiency and keeps your monthly bills low.
2. Protect Your Warranty
Did you know that most manufacturer warranties (from brands like Trane, Carrier, and Lennox) require proof of annual maintenance? If a part fails and you cannot prove the system was maintained, the manufacturer may void your warranty.
3. Extend System Lifespan
Routine maintenance reduces the stress on key components like motors and compressors. A well-maintained system can last 15–20 years, while a neglected one may fail in just 10.
4. Safety & Air Quality
For gas furnaces, maintenance is a safety issue. We check for carbon monoxide leaks, cracked heat exchangers, and gas line issues to keep your family safe.

★★★★★
I have nothing but the highest praise for Juan. He was diligent, knowledgeable, friendly, polite, shared some great info. I had initially hired Airstars to just replace a thermostat in an old oven but ended up purchasing a completely new one. No regrets. They made it painless. Will 100% hire them again for whatever appliance needs.

Frequently Asked Questions About HVAC Maintenance
How often should I service my HVAC system? Ideally, your system should be serviced twice a year: once in the spring for your Air Conditioner and once in the fall for your Furnace or Heat Pump. This prepares your equipment for the upcoming season of heavy use.
Can I do maintenance myself? Homeowners should change their air filters every 1–3 months and keep the outdoor unit clear of leaves and debris. However, tasks like checking refrigerant levels, testing electrical voltage, and cleaning internal components require professional tools and training to be done safely.
Does a tune-up really save money? Yes. The Department of Energy estimates that routine maintenance can save you up to 30% on energy costs. Additionally, catching a failing capacitor (a $150 repair) prevents it from destroying your compressor (a $2,000+ repair).
What happens if I skip maintenance? Your system will likely still run, but it will lose about 5% efficiency per year. Over time, it will become louder, cost more to run, and eventually suffer a major breakdown—usually on the hottest or coldest day of the year.
