Styles & brands we work with







Heat Pump Repair in Scottdale
Heat pump repair in Scottdale usually runs $150 – $650 parts and labor included, and it is some of the most common work we do in this part of DeKalb County. A heat pump is both a heater and an air conditioner in one unit, which means a mechanical failure in January leaves you without both functions. Most Scottdale heat pump problems we see are refrigerant leaks, failed reversing valves, or defrost control boards that stop working during damp, near-freezing nights.
What Technicians Actually Check
We start every heat pump repair with static pressure and airflow measurements, not just a parts swap. On an older Scottdale home with a single central return low on the wall, a heat pump can look dead when it is actually starved for air. We also test the reversing valve coil, check for ice on the outdoor unit, and verify the defrost cycle actually terminates when it should.
Repair Versus Replacement Logic
If your Scottdale heat pump is under 10 years old and the compressor is healthy, repair is almost always the right call. It costs a few hundred dollars versus thousands, and a written quote shows the math before you decide. If the unit is 15 or more years old, we will tell you plainly, and give you a fixed price for either path. We never steer a repair toward a sale, because our technicians are not paid on what they sell.
Heating Repair in Scottdale
Heating repair in Scottdale, whether gas or electric, generally lands between $150 and $700. The final number depends on which part failed and how much labor is involved, but you will see it in writing before we turn a wrench. A gas furnace that will not light in a cold snap is usually an ignitor, flame sensor, or gas valve. An electric furnace blowing cold air is often a failed heating element or a blower motor that has given out.
Gas Valves and Ignitors in Older Homes
Scottdale’s 1960s and 70s gas furnaces often have original gas valves that were built simple, but they do wear out. An ignitor replacement in the Scottdale area typically falls in the $150 – $300 range with labor. A gas valve repair runs higher, usually $250 – $500, because the part itself is more expensive and the job includes a full gas-pressure check after installation.
Blower Motors and Limit Switches
A blower motor failure is one of the more expensive heating repairs we do, often $300 – $600 depending on the type of motor and whether it is a variable-speed model. The interesting thing about Scottdale is how often a blower motor is not actually the problem. A restrictive return grille or a collapsed duct can make the motor work so hard that it overheats, trips the high-limit switch, and shuts the furnace down. That is why our Furnace Repair team measures static pressure before condemning a motor. Plenty of local homeowners have paid for a blower motor replacement when a $200 duct repair would have fixed it.
Trusted Brands We Service in Scottdale
We repair and maintain all major residential gas and electric furnaces, heat pumps, and air handlers. The brands we see most often in Scottdale are Trane, Lennox, Goodman, and Rheem, and we stock the parts that fail most on those units at our local supply points. That means a common ignitor, flame sensor, blower capacitor, or pressure switch is often on the truck the first visit, not a two-day order from a warehouse. Whether your furnace is 22 years old or a recent high-efficiency Rheem, the repair process begins the same way: a written price, a name and photo of your technician, and a live person on the phone when you call.
Common Furnace Repair Problems We See in Scottdale Homes
- Low return air starving the blower. Many Scottdale homes built in the 1950s through 70s have a single central return cut low on a hallway wall, often only 8 – 10 inches off the floor. The blower cannot pull enough air, the furnace overheats, and the high-limit switch trips, making a healthy furnace look cracked.
- Rusted galvanized ductwork in crawlspaces. Original 50-year-old ducts leak heat into unconditioned spaces, so even an efficient furnace leaves cold bedrooms and high gas bills. We find rusted-through trunks on a regular basis in the post-war houses around McCurdy Park.
- Short-cycling because of thermostat placement. In split-level homes, a thermostat on the main floor can read warm while the lower level stays cold, so the furnace cycles on and off all day. The furnace is fine; the single-zone design is the problem, and a repair strategy has to account for that.
- Flame sensor and ignitor failures during damp spells. Scottdale’s humid air, especially in early winter, contributes to moisture buildup inside furnace cabinets. A dirty or corroded flame sensor shuts the gas down seconds after ignition. It is a simple, inexpensive fix, usually under $200 here.

Avoid the Classic Scottdale Mistake
Here is the point of this entire page, and it is specific to Scottdale: do not spend $6,000 on a new furnace while leaving the 1962 return air and rusted ducts that will starve it and shorten its life. In a house with a single low-wall return and original galvanized ductwork, a brand-new 95% furnace will still trip limit switches, still short-cycle, and still leave rooms cold. The furnace is not the problem; the air pathway is. We will tell you that before we sell you anything, because our job is a correct, lasting repair, not a quick part change. The honest path is sometimes duct repair first, furnace second, or both together with a written plan.
Our crew responded to a no-heat call in a 1960s ranch off E Ponce de Leon Ave where the furnace would light but short-cycle. We found the hallway return grille, just 9 inches off the floor, starving the blower, and a 45-year-old galvanized return trunk rusted through in two places. After repairing the duct and calibrating the thermostat, static pressure dropped from 0.9 to 0.5 inches, and the furnace ran a full cycle without tripping the limit switch. That is not a rare story in Scottdale. It is a Tuesday.

FAQs About Furnace Repair in Scottdale
Short-cycling in Scottdale is almost always an airflow problem, not a dirty filter. Homes built in the 1950s through 70s were often constructed with one central return grille placed low on a hallway wall, too small for a modern furnace blower. The blower cannot pull enough air, the furnace overheats, and the high-limit switch shuts the burners down. The furnace runs, stops, runs again. We measure static pressure with a manometer to prove whether the return air is the issue. A duct or return modification is often the real fix, not another part. If your furnace is short-cycling tonight, call (478) 662-5175 and we will diagnose it directly.
Test the ducts before replacing the furnace. In Scottdale’s 1960s housing stock, original galvanized ductwork is often rusted through in the crawlspace, leaking heated air into the dirt. Put a new furnace on leaky ducts and you get a new furnace doing the work of an old one, without fixing cold rooms or high bills. We recommend a static-pressure and duct-leakage check before any replacement decision. If the ducts are sound, replace the furnace. If they are not, repair the ductwork first, then size the furnace to the house. Either way, you get a written price for each step and decide in full knowledge.
Yes, and the difference matters. Newer infill construction in Scottdale is built with tighter building envelopes and higher-efficiency requirements, so the furnaces are usually correctly sized, but that also means less natural air leakage. An airflow or condensate problem in a tight house shows up differently than in a leaky 1950s bungalow. Newer houses tend to present with sensor and pressure-switch faults, where older houses show overheated blowers and cracked duct seams. We send technicians who understand both housing types, because both are common within a mile of each other in Scottdale.
A light, even frost across the outdoor coil is normal in cold, damp weather, the kind of weather Scottdale gets in January. The heat pump should enter a defrost cycle, melt the frost, and return to heating within a few minutes. What is not normal is thick ice that does not melt, frost on the indoor unit, or a defrost cycle that runs constantly. Those symptoms point to a failed defrost control board, a refrigerant charge issue, or a stuck reversing valve. If your outdoor unit looks like a block of ice, shut it off at the thermostat and call us; a frozen heat pump can damage the compressor if it runs too long.
In gas furnaces, the most common reason is a failed ignitor or a dirty flame sensor. The burners light briefly, the sensor does not detect flame, and the gas shuts off, leaving the blower pushing unheated air through the house. In heat pumps, the problem is usually a stuck reversing valve or a defrost control fault, so the outdoor unit is working but the air feels cool. Both are repairable, and most Scottdale fixes fall between $150 and $500. If the air is cold and the house is dropping, call (478) 662-5175 now, and a live person will answer, 24 hours a day.
