Immediate Help for Furnace Failures
A malfunctioning furnace in Allentown, especially during the biting cold of December, January, or February, isn't just an inconvenience—it's a critical situation. Temperatures often drop to 20-25°F, and a broken furnace can quickly lead to frozen pipes, discomfort, and even health risks.

Don't wait for a small problem to become a major emergency; contact us as soon as you detect any signs of furnace trouble.
Common furnace problems we address include:
- No heat production: The most obvious sign, often due to a pilot light issue, thermostat malfunction, or a tripped breaker.
- Inadequate heat: The furnace runs but doesn't heat your home sufficiently, possibly due to a clogged filter, burner issues, or a faulty fan motor.
- Strange noises: Banging, rattling, squealing, or grinding sounds can indicate loose components, a failing motor, or issues with the blower.
- Frequent cycling: The furnace turns on and off too often, which can be caused by a dirty filter, thermostat problems, or an oversized unit.
- Pilot light issues: A pilot light that won't stay lit or isn't burning blue can signal a thermocouple problem or a gas supply issue.
- Blower running continuously: This may point to a faulty limit switch or a thermostat setting error.
Our technicians arrive with fully stocked vehicles, ensuring they have the necessary tools and parts to perform most repairs on the spot. We are committed to minimizing your downtime and restoring your comfort quickly and efficiently.

Deciding Between Repair or Replacement
When your furnace experiences a significant breakdown, especially during Allentown's cold winters, a crucial decision often arises: should you repair your existing unit, or is it more cost-effective in the long run to invest in a new furnace? This decision depends on several factors, and Mendez Heating & Cooling is here to help you evaluate your options.
Consider these points when making your decision:
When to Repair:
- Age of the Furnace: If your furnace is less than 15 years old, repairs are generally a good investment, assuming the repair cost isn't excessive. Modern furnaces are built to last 15-20 years with proper maintenance.
- Cost of Repair vs. Replacement: A good rule of thumb is to repair if the cost of the repair is less than 30-50% of the cost of a new furnace. For minor issues, repair is almost always the more economical choice.
- Frequency of Breakdowns: If your furnace has been reliable and this is its first major issue, a repair makes sense.
- Energy Efficiency: If your current furnace is relatively efficient for its age and performs well when working, a repair can extend its useful life without significantly increasing your energy bills.
When to Consider Replacement:
- Age of the Furnace: If your furnace is approaching or has exceeded 15-20 years of age, it's nearing the end of its lifespan. Older units are less efficient and more prone to breakdowns.
- High Repair Costs: If the repair cost is significant (e.g., more than 50% of a new unit), or if you're facing multiple expensive repairs, replacement often provides better long-term value.
- Frequent Breakdowns: If your furnace requires frequent repairs, the cumulative cost and inconvenience can quickly outweigh the cost of a new, reliable system.
- Declining Efficiency: Older furnaces are significantly less efficient than new models, especially those with high AFUE (Annual Fuel Utilization Efficiency) ratings. If your energy bills are steadily climbing, a new furnace can offer substantial savings.
- Safety Concerns: If your furnace is experiencing issues that pose safety risks, such as carbon monoxide leaks, it's often safer to replace the unit.
- Comfort Issues: If your home in Allentown consistently has cold spots, inadequate heating, or struggles to maintain a set temperature, a new, properly sized furnace can significantly improve comfort.
Our technicians will provide an honest assessment of your furnace's condition, clearly outlining both repair and replacement costs, and discuss the potential long-term benefits of each option. We can help you weigh the immediate cost against future energy savings, reliability, and comfort improvements, ensuring you make the best decision for your home and budget.
Local Allentown Guidelines: Permits and Requirements
Understanding local regulations is an important aspect of any home system repair or replacement, particularly for heating systems like furnaces. While routine furnace repairs in Allentown typically do not require permits, it's crucial to be aware of the specific circumstances where they might be necessary and why these regulations exist.
When a Permit May Be Required:
- Major Component Replacement: If a major component, like the heat exchanger or the entire burner assembly, needs to be replaced, this might fall under categories requiring a permit for mechanical work.
- System Replacement: Any full furnace replacement or new installation will almost always require a mechanical permit from the City of Allentown Department of Building Standards and Safety. This ensures the new system meets current building codes and safety standards.
- Significant Modifications: If your repair involves significant modifications to the existing ductwork, gas lines, or electrical connections that go beyond a simple repair, a permit could be needed.
- Fuel Type Conversion: If you are converting your furnace from one fuel type to another (e.g., oil to natural gas), this is considered a new installation and will definitely require permits, inspections, and potentially utility company involvement.
Why Permits Matter:
- Safety: Permits ensure that all work is performed according to the latest safety codes, protecting your home and family from potential hazards like gas leaks, carbon monoxide poisoning, or electrical fires.
- Compliance: Adhering to local building codes is essential for maintaining your home's value and avoiding potential issues during future home inspections or sales.
- Professional Work: Obtaining a permit typically means that the work will be inspected by a city official, which helps to ensure that the contractor performs high-quality, compliant work.
