Frequently Asked Questions

In the diverse homes of Central Texas, our skilled technicians boast over 20 years of experience in repairing all types of heating systems, such as furnaces and heat pumps. We understand the specific challenges faced by homeowners in this region, addressing issues such as inefficient heating, pilot light malfunctions, or unusual noises in furnaces, as well as concerns like pressure fluctuations and leaks. For those relying on heat pumps for energy-efficient heating and cooling, we excel in resolving temperature inconsistencies, refrigerant leaks, and defrosting problems. Our extensive experience is a testament to our commitment to delivering quality service, making us the trusted choice for homeowners who seek efficient and reliable heating system repairs in Central Texas.

If you’re noticing signs that your HVAC system isn’t operating optimally, be alert to indicators such as a lack of warm air, uneven heating or cooling, strange noises, increased energy bills, frequent cycling, pilot light issues for gas furnaces, cold or drafty spots, unusual odors, thermostat problems, and visible leaks. Should any of these issues arise, we recommend you schedule an appointment for our certified technicians to come investigate and repair. We can identify and address potential problems to ensure your home’s heating and cooling system operates efficiently, maintaining a comfortable environment in your home.

When your furnace decides to call it quits, it’s often due to some usual suspects: a finicky thermostat, pilot light or ignition system acting up, a dirty air filter causing a bit of a fuss, or maybe the limit switch is being a tad stubborn. Other culprits might be a cranky thermocouple, blower motor throwing a fit, or even a gas valve that’s decided to clock out early. Oh, and don’t forget electrical hiccups and the occasional fuel supply grumble, especially for our gas furnace pals. Sometimes, it’s just a case of the circuit breaker playing hard to get or the thermostat setting pulling a disappearing act. If your furnace decides to throw a wrench in your warmth plans, don’t stress—just give us a shout. We’re the home repair detectives you need to get to the bottom of the furnace mystery and have your home feeling toasty again.

Wondering if your HVAC is due for a little TLC or if it’s time to break up with it? Well, the signs are like the whispers of a seasoned HVAC fortune teller. If it’s playing favorites with uneven heating or cooling, chatting up strange noises, boosting your energy bills like it’s training for a marathon, or messing with your indoor air quality mojo, those are red flags.

Now, if your HVAC is still in the honeymoon phase of its lifespan and the issues are more like minor quirks, a patch-up might do the trick. But if it’s an old-timer, demanding repairs like it’s got a VIP pass, or if the repair costs could buy a small country, it might be time to consider a fresh start with a shiny new HVAC system. For the real lowdown on your HVAC’s fate, it’s always a good move to get a pro opinion. Like ours. Call Radiant Plumbing and Air – we’re the HVAC gurus who can decode the signs and tell you whether it’s a spa day or a retirement party your system needs.

Curious about the cost of fixing or replacing your heating system? Picture it like budgeting for a home makeover—expenses depend on your system’s condition and the replacement’s features. For minor tweaks, repairs might be a couple of hundred to a four-figure range. Dreaming of a new setup? Costs could range from a solid investment to a small financial adventure. Enter Radiant Plumbing and Air—we get the importance of the right heating system for your space and budget. Plus, we offer financing for unexpected expenses. Contact us today, and we’ll have your family warm and cozy in no time.

The scope of your home warranty covering heating repairs hinges on the nuances of your specific warranty plan. While these warranties typically encompass major home systems like heating, the extent of coverage can fluctuate between providers. It’s crucial to comb through your home warranty contract, deciphering the terms, limitations, and exclusions pertaining to heating system repairs. Some warranties foot the bill for both parts and labor, while others might entail specific conditions or necessitate a service fee (deductible) for each claim. To gain clarity on what’s included and the necessary steps for initiating a heating repair claim, reaching out to your home warranty provider or scrutinizing the policy documents is your best course of action.
