HVAC FAQs: Common Questions About Heating & AC Services

HVAC Answers for Green Country Homeowners

The questions below are the ones our technicians actually hear every week from homeowners in Broken Arrow, Tulsa, Bixby, Owasso, Jenks, Glenpool, Sand Springs, and the surrounding Green Country communities. Oklahoma is one of the hardest HVAC climates in the country: summer attic temperatures routinely break 140 degrees, July dewpoints sit above 70, and a single overnight ice storm in January can drop the heat load on your furnace by 60 percent in a matter of hours. Equipment that would last 20 years in a milder climate often shows its first major failure here at the 12 to 15 year mark, which is why so many of the questions on this page revolve around when to repair, when to replace, and how to extend the life of what you already own.

Okla-Home Heating & Cooling has been answering these questions from our 601 W Oakland Place headquarters in Broken Arrow since we opened, and the patterns are remarkably consistent. The two most common service calls we run are a no-cool in July (almost always a failed dual-run capacitor, a pitted contactor, or a low-charge condition from a slow refrigerant leak at the service valve) and a no-heat in January (usually a flame sensor that needs cleaning, a cracked hot-surface ignitor, or a pressure switch that has lost its draft because of a blocked flue or condensate trap). Roughly four out of every five emergency calls we run during peak season could have been prevented by a routine seasonal tune-up, which is the single biggest reason we push our maintenance plan so hard.

On the installation side, the questions are different but the theme is the same: sizing, sizing, sizing. Oklahoma contractors have a long, ugly history of oversizing equipment, which is why so many Tulsa-metro homes have two-stage or single-stage condensers that short-cycle, never pull humidity out of the air, and wear out their compressors a decade early. Every replacement Okla-Home quotes starts with a Manual J load calculation on the structure and a Manual D check on the existing duct system, because dropping a correctly sized 15 SEER2 Daikin onto undersized ductwork is a fast path to a $9,000 system that performs worse than the 20-year-old unit it replaced. The Oklahoma minimum efficiency is now 15 SEER (14.3 SEER2) for split systems in the Southwest region, and we exclusively install Daikin equipment because of the 12-year parts warranty and the variable-speed inverter platform that handles our humidity loads better than anything else in its price class.
