A heat pump is the one HVAC system that has to work year-round, cooling your Arlington home through humid summers and keeping it warm through winter cold snaps, all from the same outdoor unit. We at Infinity Heating and Air Conditioning install, repair, replace, and maintain heat pumps for homeowners throughout Arlington, and because the system never really gets an off season, it needs a contractor who understands both sides of how it runs.
Licensed for this work in Arlington and Shelby County. Infinity Heating and Air Conditioning operates under Tennessee contractor license number 68019 and serves Arlington as part of our regular Shelby County and Tipton County territory. Our technicians are trained on both the refrigeration side and the electric backup heat side of a heat pump system, which is where most misdiagnoses happen.
A heat pump usually gives warning signs before it fails outright. Call for service if you notice:
Any of these is worth a service call before the underlying issue forces a full breakdown during an Arlington heat wave or cold snap.
For a repair call, our technicians start by checking refrigerant charge, the reversing valve, the defrost control board, and the outdoor coil for fouling or ice, since these are the components most likely to cause a heat pump to underperform in either mode. For installation and replacement, we run a load calculation for your specific home rather than sizing off the old equipment’s tonnage alone, because an oversized heat pump short cycles and struggles to dehumidify Arlington’s muggy summer air, while an undersized one runs constantly and leans too hard on backup electric heat in winter.
Routine maintenance is where a lot of future repair calls get prevented. A seasonal tune up includes cleaning the outdoor coil, checking refrigerant charge, testing the defrost cycle, and confirming the electric heat strips engage properly as backup. We explain what we find at every step, and if a repair is not worth the investment on an older system, we say so and lay out replacement options rather than pushing a fix that will not last.
For some Arlington homes, particularly larger ones or homes with an existing gas furnace already in place, a dual fuel setup makes more sense than a heat pump alone. In a dual fuel system, the heat pump handles cooling and most of the heating load, while the furnace steps in only during the coldest stretches of the year, when it can produce heat more cheaply than the heat pump’s backup electric strips. We walk homeowners through whether a straight heat pump or a dual fuel setup fits their home and their existing equipment before recommending either one.

A furnace only has to get through winter, and an air conditioner only has to get through summer. A heat pump has to handle both, on the same refrigerant system, which is what makes correct sizing and maintenance more important here than on either system alone.
On the summer side, the National Weather Service’s Memphis forecast office lists a normal high near 92 degrees Fahrenheit and an overnight low near 74 degrees for much of July (2026 climate normal). Because overnight lows stay warm, a heat pump in cooling mode gets little relief to shed heat, and an oversized unit will cool the air quickly without running long enough to pull the humidity down, leaving the house cold and clammy at the same time.
On the winter side, Memphis area winters are milder, with National Weather Service climate data showing an average January low around 29 degrees Fahrenheit. A properly sized heat pump generally covers Arlington’s heating load above its balance point without leaning heavily on its backup electric heat strips. A system that is undersized, low on refrigerant, or has a fouled outdoor coil loses capacity exactly when a cold snap pushes temperatures below that normal, and falls back on backup heat strips that cost far more to run.
That is why our load calculations and our maintenance checklist both look at the system’s performance in both directions, not just the season we happen to be in when you call.
Andy G.’s review describes a ductless mini-split installation, a common type of heat pump system, rather than a traditional central heat pump, but the standard it reflects is the same one we bring to every heat pump job. He wrote that “the installers worked hard and did great work,” and after the crew returned to finish a difficult install, he added that “they did awesome work” and that his “mini-split unit is working great.” That kind of follow-through on a job that turned out to be more involved than expected is what we aim for on every heat pump installation in Arlington.

Every heat pump job is priced after we see the system and the home, because the real cost drivers vary:
We give you an upfront price before any work begins, whether that is a repair, a tune-up, or a full installation.
We at Infinity Heating and Air Conditioning bring more than a decade of HVAC experience to every heat pump call in Arlington, and a few things set that experience apart:
If you already know what your heat pump needs, our site breaks it down by service: heat pump repair, heat pump replacement, and heat pump installation. For the full picture of our HVAC work in your area, see our Arlington HVAC contractor page.
Yes, we cover the full range of heat pump work in Arlington, including new installation, replacement of aging systems, repair calls, and seasonal maintenance, all from technicians trained on both the cooling and heating sides of these systems.
A correctly sized and maintained heat pump handles both seasons well in the Arlington area, since local winter lows typically stay above the point where most residential heat pumps lose meaningful capacity. Performance problems usually trace back to incorrect sizing, low refrigerant, or a fouled outdoor coil rather than the technology itself. Homes with an existing furnace can also run a dual fuel setup, letting the furnace cover only the coldest days while the heat pump handles the rest of the year.
Yes, Infinity Heating and Air Conditioning provides 24/7 emergency heat pump repair for Arlington and the surrounding Shelby County and Tipton County service area.
The right size comes from a load calculation based on your home’s square footage, insulation, windows, and duct system, not from matching the tonnage of your old unit. We run that calculation as part of every installation or replacement estimate.
We recommend two tune ups a year, once before cooling season and once before heating season, so the outdoor coil, refrigerant charge, and defrost controls are checked before the system has to work hard in either direction.
You can book online through our website or call our office directly. For a system that has stopped heating or cooling entirely, call rather than book online so we can prioritize dispatch.
Whether your heat pump needs a repair, a tune-up, or a full replacement, book your heat pump service online and an Infinity Heating and Air Conditioning technician will size up the real problem, walk you through your options in plain terms, and give you an upfront price before any work begins. There is no obligation to move forward with a repair or an install just because we came out to look, and we would rather tell you a system still has useful life left in it than sell a replacement it does not need yet.
