The age of your water heater, along with the presence of recurring issues, leaks, or diminishing efficiency, can indicate it’s time for a replacement. MileHi HVAC can help determine if a replacement is necessary and provide expert installation services for maximum efficiency.

Can I install or repair a water heater on my own?

Water heater repairs and installations should always be handled by experienced professionals, as DIY attempts can result in hazards such as gas leaks, electrical component damage, and improper installations that may void the water heater warranty.

How often should I perform maintenance on my water heater?

It’s generally recommended that water heater maintenance be performed annually to prolong the unit’s life and maintain optimal functionality. Our professional maintenance services can detect potential issues early on and ensure your water heater operates efficiently.

What are the benefits of professional water heater installation?

Professional water heater installation offers several benefits, including:

Expertise: Trained professionals have the knowledge and experience to ensure proper installation, minimizing the risk of errors.
Safety: Professional installers follow strict safety guidelines, reducing the chances of accidents, gas leaks, or electrical hazards.
Warranty Protection: Many water heater manufacturers require professional installation for the warranty to remain valid, ensuring you’re covered in case of any future issues.
Efficiency: Professional installation ensures that your water heater operates at its maximum efficiency, potentially saving you money on energy bills.

How long does a water heater typically last?

The lifespan of a water heater depends on various factors, such as the type of unit, water quality, and maintenance. On average, traditional tank-style water heaters last about 10-15 years, while tankless water heaters can last up to 20 years or more. Regular maintenance and timely repairs can extend the lifespan of your water heater.
