INSTALLATION

Our team at Hexagon Air & Heat provides an exclusive “white-glove” heating experience that replaces common industry guesswork with high-level mechanical engineering. This elite process begins with a proprietary evaluation of your home’s specific thermal envelope, moving far beyond standard square-footage estimates to treat your heating infrastructure as a significant long-term investment.

By utilizing our Precision Design Suite, we perform a scientific audit of your home’s unique orientation, insulation profiles, and winter heat-loss variables to ensure your furnace or heat pump is perfectly calibrated. This meticulous design phase guarantees that your system is not merely sufficient for the cold, but specifically engineered to maximize heat distribution and long-term fuel efficiency, providing total peace of mind and unwavering warmth for the most discerning homeowners.

REPAIR

When facing a decision about your heating system’s reliability, several crucial variables come into play to determine whether a precision repair or a full system replacement is the most sound investment.

Key factors include the age of your current furnace or heat pump; units over 12 years old often require more frequent, costly repairs and operate at significantly lower efficiency. We meticulously evaluate the repair history to assess if you are experiencing repeated component failures, such as failing igniters or cracked heat exchangers. Furthermore, the overall efficiency (AFUE for gas or HSPF2 for heat pumps) is vital; older systems can cost hundreds of dollars more in winter utility bills.

At Hexagon Air & Heat, we go beyond guesswork by using our proprietary Precision Design Suite, evaluating your home’s specific thermal envelope, window orientation, and insulation profiles to ensure your heating infrastructure is perfectly engineered for your specific needs, rather than relying on outdated “rules of thumb.” To assist you in weighing these complex technical and financial factors, please refer to our Climate Assessment, which maps out common scenarios based on system age, expected life in our specific coastal environment, and the efficiency gains of modern mechanical engineering.

MAINTENANCE

Regular heating maintenance is the “health insurance” of your home, transforming your mechanical system from a vulnerable appliance into a high-performance asset. In the fluctuating winter temperatures of the Greater Houston area, a neglected system works twice as hard to achieve consistent warmth, leading to uneven heating and premature fatigue of critical components like the heat exchanger and blower motor.

Beyond immediate comfort and safety, consistent professional service is a contractual necessity; most major manufacturers, including Lennox, Trane, and Carrier, explicitly require documented annual maintenance to keep their 10-year parts warranties valid. Without a professional paper trail, a simple component failure can turn into a multi-thousand-dollar out-of-pocket expense.

By combining monthly homeowner tasks, like filter changes to ensure proper airflow, with Hexagon’s exclusive Precision Tune-Up, you effectively “stop the clock” on system aging. This engineering-led approach ensures your investment remains energy-efficient, your home remains protected against carbon monoxide risks, and your legal warranty protection stays ironclad.

HAVEN Smart Thermostats

Hexagon is grateful for the opportunity to work with our Greater Houston neighbors. To ensure your home’s architectural legacy is protected against Houston’s humidity, we are offering a HAVEN Smart Thermostat (24/7/365 monitoring) with all new system installations.

This Smart Thermostat notifies Hexagon immediately if your system requires attention and allows you the peace of mind of knowing your system is cooling or heating your home as expected.

*Available for purchase for existing systems, 24/7/365 monitoring included

ORDER YOUR FILTERS

When calculating the costs of air filtration, it is vital to consider how filter maintenance directly protects your heating investment. While high-efficiency filters—such as those used in a Lennox Carbon Clean 16—may have a higher initial cost, their superior design allows for a longer lifespan and significantly better protection for your furnace or heat pump. For instance, a 4-inch media filter can often last up to six to twelve months, making it more economical and technically sound than standard 1-inch filters that require monthly replacement.

Neglecting to change your heating system’s air filter regularly can lead to catastrophic failures that impact both indoor air quality and the mechanical integrity of your system.

Mechanical Strain and Safety

A clogged filter restricts the vital airflow required to cool the heat exchanger in a gas furnace. Without sufficient air moving over this component, the furnace will overheat, leading to “short-cycling” and dangerous stress fractures in the metal. Over time, this extra load causes blower motor fatigue and costly, premature system failure. Replacing filters on time is the single most effective way to extend the lifespan of your heating infrastructure and ensure the safety of your home.

Energy Efficiency and Cost

Furthermore, when your system struggles to draw air through a dirty filter, it must run for significantly longer periods to meet your thermostat’s demand, consuming excessive energy. This increased usage results in spiked utility bills and a larger carbon footprint. Regular filter changes ensure your system operates at its laboratory-tested AFUE or HSPF2 ratings, keeping your heating costs predictable and your indoor comfort consistent throughout the winter.

We recommend the “50% Rule.” If the cost of a single repair is 50% of the value of a new system, or if the unit is over 15 years old and requiring frequent fixes, replacement is usually the smarter investment. Newer systems are often 20–30% more energy-efficient, meaning the upgrade can eventually pay for itself through lower utility bills.

his is often caused by one of three simple issues:

  • Thermostat Settings: Ensure it’s set to “Auto” rather than “On” (which blows air even when the furnace isn’t heating).

  • Air Filters: A clogged filter restricts airflow, causing the system to overheat and shut down its burners as a safety precaution.

  • Pilot Light/Ignition: For gas furnaces, the igniter may be dirty or faulty, preventing the flame from catching.

While the “standard” advice is every 3 months, it depends on your household. If you have pets, allergies, or a large family, you should check them every 30 days. A clean filter is the single best way to prevent expensive internal component failures and keep your indoor air quality high.

This is usually a “zoning” or “distribution” issue rather than a furnace failure. Common culprits include:

  • Leaky Ductwork: Hot air is escaping into your attic or crawlspace before it reaches the room.

  • Blocked Vents: Furniture or curtains may be obstructing airflow.

  • Unbalanced Dampers: Your duct system may need to be adjusted to push more air to the furthest rooms.

Yes. Most manufacturers require annual professional maintenance to keep your warranty valid. Beyond the warranty, a tune-up identifies small issues—like a frayed belt or a cracked heat exchanger—before they turn into “no-heat” emergencies in the middle of a freeze. It’s the difference between a $150 maintenance visit and a $3,000 emergency repair.
