A failing water heater isn’t just inconvenient—it’s a disruption. At Air Control Heating and Air, we make water heater repair and replacement simple, stress-free, and cost-efficient.

Repair. Replace. Relax.
No hot water? Leaks? Pilot light won’t stay lit? We’ll get to the root of the problem and give you clear options. If a repair will do the job, we’ll fix it. If not, we’ll help you choose a reliable, energy-efficient replacement that fits your lifestyle and budget.
Water Heater Repair
Just because your water heater is giving you the cold shoulder doesn’t mean it’s time to buy a new one. In many cases, it’s a minor issue that can be easily repaired. Here are issues we frequently address:
- Faulty thermostats and heating elements
- Pilot light or ignition issues
- Sediment buildup
- Leaks from fittings, valves, or connections
- Inconsistent or lukewarm water
Water Heater Replacement
When repair isn’t enough, our team makes water heater replacement simple. We’ll guide you through your choices, remove your old unit, and install a new system, whether it’s:
- A traditional tank water heater (gas & electric)
- A tankless system that provides endless hot water
- An energy-efficient model that lowers monthly utility bills
Comfort starts with the right fit. We’ll make sure your new water heater is properly sized, installed with care, and perfectly matched to your home, lifestyle, and budget.
Water Heater Service
The best way to avoid costly breakdowns? Stay on top of maintenance. Our water heater service techs catch small issues early—before they turn into expensive repairs. During a typical water heater service, we’ll:
- Drain and flush the tank to clear out sediment buildup
- Inspect fittings, valves, and connections for leaks
- Test the thermostats
- Check the anode rod for corrosion
- And ensure your system is running at peak performance
Signs You Need Water Heater Repair
Sometimes it’s not obvious if your water heater needs a quick fix or something more. Call us if you notice:
Hot Water Runs Out Quickly
Cold showers are often caused by worn heating elements, a faulty thermostat, or sediment buildup inside the tank.
Rumbling or Banging Noises
Is your water heater talking back? Strange sounds usually point to sediment at the bottom of the tank, which can often be flushed out.
Inconsistent Temperatures
Hot one minute, ice cold the next? Inconsistent heating usually means your thermostat or heating element needs adjustment or repair.
Small Leaks
Drips from fittings or valves can often be tightened or replaced without investing in a whole new unit.
Stubborn Pilot Lights
If your pilot light refuses to stay lit, it’s often an ignition issue with gas water heaters—something our techs can repair or replace.
Signs You Need Water Heater Replacement
Some water heater problems are tougher to bounce back from. It may be time to replace your system if:
Your Unit Is 8–10+ Years Old
Most water heaters don’t last much longer than a decade. As they age, efficiency drops, and the risk of leaks or failure increases.
You Notice Rust-Colored Water or Corrosion
If you see rust in your hot water or notice visible corrosion on the tank, it’s usually a sign that the tank itself is failing. Unfortunately, this is an issue that can’t be repaired.
Your Tank is Cracked
Small drips from valves can often be fixed, but leaks or cracks in the tank mean it’s time for a full replacement.
You Notice Energy Bill Spikes
Older water heaters work harder to do the same job, which means higher monthly costs. A new, efficient system can save money long-term.
You’re Making Frequent Repairs
If you’re calling us every few months, replacement is often more cost-effective than pouring money into an old unit.
When replacement makes sense, we’ll help you choose a new water heater that’s properly sized, energy-efficient, and built to keep up with your household’s needs.
Signs You Need Water Heater Service
Even if your water heater isn’t broken, it still needs routine service to keep it running at its best. Call us if you notice:
Water Takes Longer to Heat
If it feels like you're waiting on hot water, sediment buildup or minor wear may be slowing it down. A professional flush and inspection is often enough to restore performance.
Strange Odors or Discolored Water
Cloudy water, metallic tastes, or musty smells often mean your tank needs cleaning or the anode rod needs attention. Left untreated, these issues can lead to corrosion or bacteria growth.
Higher-Than-Normal Energy Bills
Notice a sudden energy bill spike? A water heater that isn’t serviced regularly has to work harder, which drives up utility costs.
It’s Been Over a Year Since Your Last Checkup
Even if your water heater seems fine, annual service is essential to catch small issues before they turn into big ones. Think of it like an oil change for your car—regular care keeps everything running smoothly.
You Own a Tankless Water Heater
Tankless systems are efficient, but they still need annual descaling and filter cleaning to prevent mineral buildup. Skipping service can shorten the lifespan of your investment.
