Frequently Asked Questions

As Central Texas’s go-to plumbing experts, we’re here to guide you on when it’s time to bid farewell to your heating system. This decision involves weighing various factors such as age, recurring repairs, escalating energy bills, erratic heating behaviors, strange noises, visible wear, and thermostat hiccups. If your reliable system has clocked in at the 15-20-year mark, demands frequent and budget-draining repairs, or exhibits efficiency quirks, it’s signaling the need for a replacement. Those peculiar sounds, uneven heating, and visible wear are additional red flags. For a tailored expert assessment aligned with your heating system’s unique journey, trust the HVAC professionals at Radiant Plumbing and Air. Our thorough checkup will pinpoint the best next steps for your home’s heating solutions.

The typical lifespan of a new furnace hovers around 15 to 20 years. However, this range can fluctuate based on factors like unit quality, consistent maintenance, and proper sizing for the home. High-quality furnaces receiving regular maintenance may surpass the upper end of this range, ensuring longevity, while lower-quality units or those with frequent issues might have a shorter lifespan. To optimize your furnace’s performance and extend its efficiency, diligent monitoring, prompt repairs, and routine maintenance are key. As a general rule, if your furnace approaches the 15-20 year mark, even if it’s still operational, considering replacement is advisable. This proactive approach helps mitigate potential breakdowns and boosts energy efficiency with newer models.

Choosing the right heating system for your home can be a daunting task, especially if your house hails from the 1950s. Heating technology has come a long way since then, making the process of ensuring your home stays comfortably warm with the right-sized system even more challenging. With the introduction of new energy-efficient features and power supplies like solar and gas, deciphering the ideal home heating system has become more complex than ever. However, when you reach out to Radiant Plumbing and Air, our expert team takes the reins. We not only prioritize repairing your existing system but, if necessary, guiding you through the process of replacing or installing a new heating system. Our technicians and customer support teams navigate the evolving technology landscape, deciphering requirements, and identifying potential rebates you may be eligible for. Spend more quality time with your family and less time stressing over home repairs. Call Radiant today for reliable and hassle-free solutions.

The associated costs can vary based on factors like furnace type, efficiency, home size, and installation complexity. Typically ranging from $2,000 to $7,500, this includes the furnace unit, labor, and additional materials. High-efficiency furnaces or those with advanced features may lean towards the higher end. To get an accurate estimate aligned with your specific needs, reach out to us at Radiant Plumbing and Air. Our expert team can assess your requirements, recommend the right-sized unit, and provide a precise cost estimate, factoring in rebates available to Texas homeowners and installation specifics for your home. Don’t hesitate to call us for a comprehensive and accurate quote tailored to your home’s heating needs.

Thinking about taking on the challenge of replacing your furnace on your own? While some with advanced DIY skills might contemplate it, handling a furnace installation involves intricate electrical work, gas lines (for gas furnaces), ventilation, and system calibration. For Texas homeowners, tackling this task independently is not advised. Not only does it demand a deep understanding of local building codes and safety regulations, but incorrect installation can pose serious safety hazards, such as gas leaks or improper ventilation. Your family’s safety is our priority at Radiant Plumbing and Air, and that’s why we strongly discourage DIY furnace installation. Our licensed HVAC professionals possess the expertise to ensure a safe, code-compliant installation, optimal system performance, and adherence to warranty requirements. Save time, avoid risks, and reach out to Radiant Plumbing and Air for a swift and secure furnace replacement. Call us today for a quote and inquire about financing options for your new furnace.

Gas, oil, and electric furnaces differ in their fuel sources and heating mechanisms. A gas furnace burns natural gas or propane, an oil furnace uses heating oil for combustion, while an electric furnace relies on electricity to generate heat through resistance heating elements. Gas furnaces are common for efficiency, oil furnaces are used where gas is unavailable, and electric furnaces are chosen based on factors like cost and practicality. The decision depends on fuel availability, local climate, and specific homeowner preferences. Here at Radiant Plumbing and Air, we’re your go-to experts for servicing, installing, and repairing all these furnace types. So, whether you’re weighing efficiency, availability, or homeowner preferences, we’ve got you covered. Reach out to us for comprehensive solutions tailored to your heating needs.

Boilers, furnaces, and heat pumps each serve distinct heating functions with unique mechanisms. Boilers, operating on various fuels, heat water and circulate it through radiators or pipes for even warmth. Furnaces, powered by gas, oil, propane, or electricity, use combustion to generate heat and distribute it through ducts. Heat pumps, reliant on electricity, transfer heat between indoors and outdoors. The choice among these systems depends on factors like fuel availability, climate, and homeowner preferences. Factors such as efficiency, distribution methods, and overall suitability for specific heating needs play a crucial role in making the right decision. At Radiant Plumbing and Air, we specialize in servicing, installing, and repairing all these heating systems. Contact us for tailored solutions aligning with your home’s heating requirements.
