Frequently Asked Questions

Most contractors skip load calculation and guess at system size, leading to undersized units that can't keep up or oversized ones that short-cycle and waste energy. Proper calculation accounts for home square footage, insulation, ductwork, and Alabama cooling load. Brookwood's mix of older and newer construction demands accurate sizing—each home is different.

Static pressure testing measures airflow resistance through ductwork after installation to confirm the system moves air efficiently. High pressure means restricted airflow from undersized ducts, closed dampers, or dirty filters—all reduce efficiency and shorten equipment life. Testing verifies the system delivers rated performance, not just turns on.

Humidity stresses coils and compressors year-round in Alabama, accelerating corrosion and refrigerant loss. Seasonal maintenance before summer and winter catches wear before peak demand when systems fail most often. Coil cleaning, refrigerant charge verification, and electrical connection inspection prevent breakdowns during the months you need cooling and heating most.

Regular maintenance is the difference. Systems that get seasonal tune-ups—refrigerant checks, coil cleaning, airflow verification, filter replacement—last five years longer on average than neglected ones. Manufacturers require this maintenance to honor warranty, and it prevents the efficiency loss that drives up utility bills as systems age.

Age and failure type determine the decision. Compressor or refrigerant circuit failures on systems over eight years old often cost more to repair than replace. Control board issues, clogged condensate lines, or dirty coils are straightforward repairs at any age. Inverter compressor diagnostics require brand-specific training most techs don't have.

Leaky ducts waste 20-30% of heated air in many older homes, so a new high-efficiency furnace can't deliver rated performance without sealing first. Static pressure testing after sealing confirms airflow meets design specs. Installing new equipment on bad ductwork means paying for efficiency you'll never see on your utility bill.

Flame sensor fouling, ignition system failures, and blower motor issues cause most winter breakdowns. Sensors collect carbon buildup that prevents ignition; motors wear out from lack of lubrication; gas pressure drifts out of spec. Systematic diagnosis before replacing parts prevents repeat service calls and identifies root cause, not just symptoms.

Household gallon-per-hour demand determines tank size—number of bathrooms, occupants, and simultaneous use patterns all factor in. Undersized tanks run out of hot water during peak morning use; oversized ones waste energy heating water you don't need. Load calculation before installation matches capacity to actual demand, not guesswork.

Inspection measures static pressure, verifies refrigerant charge, checks electrical safety, inspects heat exchangers for cracks, and assesses ductwork for leaks and blockages. Older systems hide efficiency losses and safety faults that show up in detailed testing. A written report documents true system condition before you commit to buying the home.

Mineral deposits from local water settle at the bottom of tank heaters, insulating the heating element from water and forcing it to run longer to reach temperature. This wastes energy and shortens element life. Periodic flushing removes sediment before it hardens into a layer that reduces tank capacity and efficiency noticeably.
