When to Call
Signs Your Heating System Needs Attention
Catching problems early avoids emergency repairs and extends equipment life.
- Unusual noises — banging, rattling, squealing, or popping when the system runs or starts up
- Uneven heating — some rooms stay cold regardless of thermostat setting
- Rising energy bills — heating costs increasing without a change in usage or weather
- Short cycling — the system turns on and off repeatedly without reaching the set temperature
- Yellow or orange pilot flame — a healthy gas furnace flame is blue; other colors indicate incomplete combustion
- System over 15 years old — older furnaces with frequent repairs are candidates for replacement
- No heat at all — call 510-848-5010, including after hours

What Customers Say About Aarvaks
★★★★★
“My furnace was clearly dying right before Christmas! Jason and the team at Aarvaks got me a good deal on a new furnace, and got it installed before the holidays. They were responsive, helpful and professional. Fully recommend!”
★★★★★
“No words. These guys were great. They not only did the job but went above and beyond to help resolve a separate but related issue. All the guys were great but Jose gets a special shout out for extra effort!!! The job was just completed a couple hours ago so so far so good. Highly recommended!”
★★★★★
“Jason the owner of Aarvaks gave me an amazing estimate I could work with and explained to me how much money I’ll be saving from converting from gas to a full electric system. Jason was professional, punctual, and clearly very knowledgeable and the amazing installers who installed my new Bosch heat pump system were Jose, Rafa, and Orlando. Jose took the time to explain the system, answered all of our questions, and made sure everything was set up perfectly. The installation itself was smooth and efficient, and they left the workspace clean when they were done. Our new heat pump is already making a big improvement in comfort and efficiency. Highly recommend this company if you’re looking for reliable, high-quality HVAC work.”

Common Questions
Frequently Asked Questions
How much does furnace installation cost in Berkeley?
Furnace installation at Aarvaks starts at $7,500. The final cost depends on the furnace model, ductwork condition, and any additional work required such as gas line or electrical upgrades. We provide a written quote before any work begins. Call 510-848-5010 or book online for a free estimate.
How much does a heating diagnostic cost?
The residential diagnostic fee is $79, waived if we do the repair. The commercial diagnostic fee is $189.
What heating brands does Aarvaks install?
We are an authorized dealer for Carrier and Bosch and also install Mitsubishi and Navien systems. We repair all major brands including Lennox, Trane, Goodman, Rheem, and American Standard.
Does Aarvaks offer emergency heating service?
Yes. Call 510-848-5010 for emergency heating service across the East Bay and North Bay, including after hours.
How often should I have my furnace serviced?
Once per year, ideally in early fall before the heating season begins. An annual tune-up includes cleaning the heat exchanger, checking the igniter and burners, testing safety controls, and verifying airflow. The cost is $129, or $199 for a combined furnace and AC tune-up.
Should I repair or replace my furnace?
If the repair cost exceeds 50% of the replacement cost and the system is over 15 years old, replacement is typically the better investment. We assess both options, including any rebates that apply, and give you the numbers before recommending anything.
Are there rebates available for heat pump installation in Berkeley?
The federal 30% tax credit for heat pumps, up to $2,000, covered improvements made through December 31, 2025, so it does not apply to systems installed in 2026. Some local utilities offer heat pump rebates. MCE, for example, offers up to $400 per 500 square feet in communities it serves, such as El Cerrito and Richmond. Heat pump installation starts at $17,000 before rebates. We identify which rebates apply during the estimate process. See current rebates in the East Bay and North Bay or call 510-848-5010 to discuss what you qualify for.
What warranty comes with a new heating system from Aarvaks?
Every installation comes with two warranties. The manufacturer covers the parts; on a Carrier furnace in a home, that is 10 years for the original owner. We cover our installation work: if something we did isn’t right, we fix it at no labor charge for 3 years, or 5 if the system gets a tune-up every year. Full warranty terms.
