HVAC Company in Krum, TX
Krum sits on the northern edge of the Dallas-Fort Worth metro where hot summers and sudden winter snaps hit hard, and the housing stock is a mix of newer construction and older, larger-lot homes that each fail differently. We’re Dalton Heating & Air, and we handle AC repair, heat pump installation, and furnace repair across Krum with one non-negotiable rule: a written price before any work starts. The local jobs we see most involve overworked condensers in July and heat pumps sized wrong for Krum’s freeze-thaw cycles. Call (361) 306-9515 and a live person answers, day or night.
Why Krum Homes Are Different
Krum’s older homes, many built in the 1970s and 1980s along streets like McCart and 4th, often run original ductwork that leaks conditioned air into attics that hit 140°F in August. That means a perfectly good AC unit can still leave a bedroom at 80 degrees because the real problem is in the ducts, not the compressor. Newer subdivisions around Krum High School and the eastern edge of town tend to be tighter builds, but their HVAC systems get undersized when builders cut costs, and we see them struggle on the first 100-degree day.
Soil matters here too. Krum sits on clay that shifts with rainfall, and foundation movement can knock a furnace cabinet out of level or stress refrigerant lines where they enter the wall. Piers and slabs move, and so do the copper lines running through them. We also see plenty of rural properties around Krum with propane or all-electric setups instead of natural gas, which changes how we diagnose a furnace that won’t light or a heat pump that won’t switch to defrost mode.
Our Main Krum Services
Most calls to Dalton Heating & Air from Krum fall into three buckets: cooling systems that quit in the middle of a heat wave, heat pump installs on homes switching away from electric resistance heat, and furnaces that won’t fire on the first cold night of the year. Each has its own page below with the pricing, the process, and what to expect.
AC Repair in Krum
Krum’s summer heat is relentless, and most AC failures here announce themselves on a Friday afternoon when the temperature tops 102°F. We arrive inside the stated window, diagnose the issue, and hand you a written price before a single part comes off the truck. Typical Krum AC repairs run from a $150 capacitor swap to a $650 condenser fan motor replacement. No overtime charge, no price that shifts at the door. AC Repair in Krum covers what we fix, what it costs, and how fast we can get there.

Heat Pump Installation in Krum
More Krum homeowners are replacing straight electric furnaces with heat pumps, especially on rural lots where natural gas never got run. Heat pumps make sense in North Texas winters that stay mild but still dip below freezing, and they give you real air conditioning in summer without a separate system. The install requires careful sizing, and we run load calculations rather than guessing. In Krum’s newer homes with tight building envelopes, an oversized heat pump short-cycles and drives up humidity. Heat Pump Installation in Krum explains the process and the brands we carry.

Furnace Repair in Krum
Furnace failures in Krum cluster in December and January, when a cold front drops temperatures 30 degrees overnight. Gas valve failures, ignitor burnout, and blower motor problems lead the list. Older Krum homes with propane tanks have their own set of issues with regulators and supply lines. Every furnace repair comes with a full-year written guarantee: if the part fails within that time, we return at no charge. Furnace Repair in Krum breaks down the most common repairs and their price ranges.
