When Heat Fails in Dunedin: A Detailed Heating Repair Guide

Greetings, Dunedin homeowners and building management professionals! As we all know, our beloved city is known for its warm, sunny weather. But when the temperature drops and our heating systems fail, it can be as chilling as a dip in the Gulf of Mexico in January.

At Pronto Service Pros, we understand the importance of a well-functioning heating system, especially during those rare cold snaps. This blog post will guide you through the process of heating repair, focusing on what to do when your heat cuts out.


Understanding Your Heating System

The initial step in resolving any heating issue is gaining a thorough understanding of your heating system. In the United States, gas furnaces and heat pumps are the most prevalent types of heating systems. A gas furnace operates by burning natural gas to generate heat for your home, while a heat pump employs electricity to transfer heat from one location to another. Both these systems can encounter issues such as a cracked heat exchanger, a crucial component of natural gas furnaces, leading to heat loss.

For those using a window AC unit, a portable AC, or a space heater, it’s important to note that the heating capacity might not be as robust as a dedicated heating system. These systems often have a lower BTU rating, which means they may not heat your space as quickly or as effectively as a larger, more powerful system.

However, there’s no need to fret. Our HVAC technicians at Pronto Service Pros are proficient in all types of heating and AC repair, including systems with a cracked exchanger or those needing a boost in their BTU rating. Whether you’re dealing with a malfunctioning portable AC or a space heater that’s not up to par, we’ve got you covered.


Signs of a Heating System Failure

  • Absence of Heat or Cool Air

The most glaring indication of a heating system failure is when your home fails to warm up, despite the thermostat being set to a high temperature. This could be attributed to a range of issues, from a malfunctioning thermostat to a cracked heat exchanger, a primary component of natural gas furnaces. This is also a common issue with portable air conditioners, which may struggle to provide adequate heating.

  •  Unusual Noises

If your heating system is producing strange noises, it could be a sign of an underlying problem. A well-functioning system should operate with minimal noise.

  • Distinctive Smells

Should you detect a smell reminiscent of rotten eggs or sulfur, it could be indicative of a gas leak. Natural gas, the primary component of natural gas furnaces, is often mixed with hydrogen sulfide by providers to make leaks easier to detect due to its distinctive rotten egg smell.

  • Flu-Like Symptoms

Exposure to carbon monoxide, a harmful byproduct of burning natural gas, can cause symptoms similar to the flu. If you and your family start experiencing these symptoms, it’s crucial to evacuate the house immediately and contact your natural gas provider.

  • Increased Energy Bills

A sudden spike in your energy bills could be a sign that your heating system, including portable air conditioners, is not operating efficiently. This could be due to various factors, including a cracked exchanger, which would require immediate attention and repair.


What to Do When Your Heat Cuts Out

  • Check Your Thermostat

Before calling for emergency heating repair, check your thermostat. Ensure it’s set to “heat” and the temperature is set higher than the current room temperature. If you’re using a programmable thermostat, make sure the schedules are set correctly.

  • Inspect the Air Filter

A dirty air filter can restrict airflow and cause your heating system to work harder, increasing energy consumption. Regularly replacing your air filter is an essential part of HVAC maintenance.

  • Call a Professional HVAC Technician

If your heating system is still not working after checking the thermostat and air filter, it’s time to call a professional HVAC technician. At Pronto Service Pros, our technicians are experienced in all types of heating and air conditioning repair, from gas furnaces to window air conditioners.


The Importance of Preventative Maintenance

Regular preventative maintenance can help prevent heating system failures and extend the life of your system. It can also improve energy efficiency, reducing your energy bills. At Pronto Service Pros, we offer comprehensive HVAC maintenance services to keep your system running smoothly.



When the heat cuts out, it can be as unsettling as a sudden thunderstorm during a Dunedin Blue Jays game. But with a little knowledge and the help of a professional HVAC technician, you can get your heating system back up and running in no time. Remember, regular preventative maintenance can help prevent heating system failures and keep your home cozy and warm, no matter the weather outside.

Stay tuned for the second half of this comprehensive guide, where we’ll delve deeper into the intricacies of heating repair, including the dangers of a cracked heat exchanger, the importance of a carbon monoxide detector, and how to choose an energy-efficient heating system. Until then, stay warm, Dunedin!
