Common Signs You Need Heater Repairs
Recognizing the early signs of heater trouble can save you from unexpected breakdowns and costly repairs. Some of the most common indicators your heating system needs attention include:
- Uneven heating when some rooms are too hot, while others remain chilly.
- Unusual noises such as banging, rattling, or squealing sounds coming from your system.
- Frequent cycling where your heater turns on and off more often than usual.
- Higher energy bills without an increase in usage.
- Strange musty, burning, or gas smells when the heater is running.
- A complete lack of heat or a system that won’t turn on.
Eventually, your heater will need repairs, as it sees a lot of use, especially during Denver’s cold winters. When you notice these issues, it’s important you get professional help as soon as possible. We can help quickly diagnose the problem to avoid bigger problems down the line.

Repairs vs. Replacements: Which Is Best for My Heater?
It’s a common dilemma for property owners faced with a faulty heating system: to repair or replace? The right choice depends on factors like the age of your system, the extent of the issue, and your budget.
Opt for repairs if your system is less than 10 years old and the damage is minor or repair costs are below 50% of the replacement cost. Consider replacement, however, if your system is over 15 years old, has required frequent repairs, or your energy bills have been rising significantly.
At Allen Service, we’ll honestly assess your heating system and provide you with guidance to make the best decision for your needs. Whether it’s a cost-effective repair or a complete upgrade, our goal is to deliver solutions that align with your comfort and budget.
