Our Achievements

Our Mission: Comfortable And Energy Efficient Homes

At IRBIS HVAC, our mission is to ensure that every home has an HVAC and plumbing system that provides maximum comfort and energy efficiency.

Typical Issues We Handle Every Day

From no hot water to strange noises — we’ve seen it all and fixed it all

Pilot light won't stay lit

What causes it: A worn thermocouple or a clogged pilot orifice keeps shutting the gas valve down.

‍What we do: We clean or swap the thermocouple, test the gas valve, and confirm a steady flame.

Heating element failed (electric units)

What causes it: Mineral scale or age burns out an upper or lower element on an electric tank.

‍What we do: We test each element with a meter, replace the failed one, and check the recovery time.

Tankless unit showing an error code

What causes it: A scale in the heat exchanger or a venting fault trips the unit into a fault code.

‍What we do: We read the code, descale the exchanger, and check venting before clearing the fault.

Leaking from the bottom of the tank

What causes it: Internal corrosion has reached the steel shell, so the tank itself is failing.

‍What we do: We confirm the source and give you honest repair-versus-replace options, never a hard sell.

Leaking from a pipe connection on top of the unit

What causes it: Loose nipples, a failed flex connector, or a worn dielectric union let water seep.

‍What we do: We reseal or replace the fitting and pressure-check the joint before we leave.

Rotten egg smell from hot water taps

What causes it: Bacteria reacting with the anode rod produce a sulfur odor in your hot water.

‍What we do: We disinfect the tank and fit a low-odor anode rod suited to local water.

Popping or rumbling sounds from the tank

What causes it: Sediment hardens at the base, and steam bubbles burst through the scale layer.

‍What we do: We flush the tank, clear the sediment, and restore quieter, faster heating.

Pressure relief valve dripping or leaking

What causes it: High tank pressure, thermal expansion, or a tired valve forces water past the seal.

‍What we do: We test pressure, check the expansion tank, and replace the valve when it fails.

Repair or Replace Your Water Heater?

Call Us Now

Most water heaters need repairs, not replacement. You’ll likely need a repair if the unit is under 10 years old, the tank is dry, and one part is at fault. Replace if it leaks from the shell, fails repeatedly, or passes 12 years, where a new water heater installation often costs less long term. San Jose's hard water (250 to 300 mg/L) shortens tank life, so routine water heater maintenance, flushing sediment and checking the anode rod helps your unit reach its full lifespan and delays the need for repairs.

Questions & Answers

Frequently
Asked Questions

Quick answers about San Jose water heater repair: timing, cost, and what to expect from our licensed plumbers.

How quickly can you repair a water heater in San Jose?

Most San Jose repairs finish the same day. We aim for one visit, and stocked vans carry the parts that fix common gas and electrical faults.

Do you offer 24-hour water heater repair?

Our emergency line answers 24 hours a day. Technicians dispatch during business hours, and we prioritize same-day appointments for urgent no-hot-water calls.

How much does water heater repair cost in San Jose?

Cost depends on the part and system type. Every visit starts with a flat-rate written quote, no parts markup, and members save up to 20%.

Can you repair tankless water heaters?

Yes. We service tankless units, including descaling the heat exchanger, clearing error codes, and checking venting so your on-demand system heats correctly again.

Is it worth repairing an old water heater or should I replace it?

Under 10 years with a single fault, repair makes sense. Past 12 years or leaking from the tank, replacement usually costs less over time.

What's the most common reason for no hot water?

For gas tanks, a pilot or thermocouple fault. For electric tanks, a failed heating element. We test both and restore hot water fast.

Do you charge extra for same-day or emergency repair?

No. We use flat-rate pricing, so same-day and emergency calls cost the same as scheduled visits, with no hidden fees or parts markup.

How Long Do Water Heaters Really Last?

A reliable supply of hot water is often taken for granted until the first cold shower of the morning. Most homeowners ignore their water heaters because they are tucked away in garages or closets, yet these units are under constant pressure and thermal stress.
