Look for a company that’s licensed and insured, has positive customer reviews, employs NATE-certified technicians, offers upfront pricing with no surprise fees, provides written estimates, guarantees their work, and has experience with your specific furnace brand.

Your furnace may still produce heat while hiding problems beneath the surface. Call for service if you notice:

• Uneven heating or cold spots
• Strange smells or unusual noises
• Higher-than-normal energy bills
• Frequent on/off cycling
• Weak or inconsistent airflow
• Cool air blowing from vents
• A furnace that struggles to maintain temperature

These warning signs mean your system needs attention before the issue gets bigger — or more expensive.

Luke’s Plumbing & Air Conditioning services gas, electric, propane, and high-efficiency furnaces, as well as dual-fuel heating systems used in some Houston-area homes. From older legacy units to the newest smart, high-performance models, our technicians are trained to work on all major brands.

Most furnace manufacturers — and energy experts — recommend professional furnace maintenance once a year. An annual tune-up keeps your system efficient, safe, and reliable during Houston’s unpredictable winter cold fronts. Routine service also helps protect your warranty and reduces the chances of a mid-season breakdown.

The most effective way to prevent furnace problems is scheduling annual professional maintenance before winter. Additionally, change air filters every 1-3 months during heating season, keep the area around your furnace clean and unobstructed, ensure all vents are open and unblocked, install a carbon monoxide detector near your furnace, and address unusual noises or performance issues promptly. These simple steps are especially important in Houston where furnaces often sit unused for extended periods, making them more susceptible to dust accumulation and component issues when suddenly activated.

This decision depends on several factors: age (if over 15 years, replacement often makes more sense), repair frequency and costs (multiple repairs in recent years suggest replacement), efficiency (older units waste 30-40% more energy), and performance (consistent comfort issues indicate it’s time for an upgrade). For Houston homes, where heating demands are less intense than in northern climates, properly sized, high-efficiency furnaces often provide the best balance of upfront cost and long-term energy savings.
