Heat pumps are complex systems, and subtle warning signs often point to specific component failures. Here are the most common issues our technicians encounter in Mokena homes:

• System stuck in cooling mode and won’t switch to heat — often a failed reversing valve
• Ice or frost buildup on the outdoor unit — caused by defrost cycle failures or refrigerant issues
• Short cycling (unit turns on and off rapidly) — can indicate refrigerant leaks or electrical faults
• Auxiliary or emergency heat running constantly — often a sign the heat pump isn’t extracting sufficient heat
• Unusual clicking, grinding, or rattling noises — pointing to worn fan motors or loose components
• Unexplained spike in monthly electric bills — frequently tied to refrigerant loss or coil inefficiency

Whether your aging system has finally given out or you’re building new and want the most energy-efficient option available, TemperaturePro’s installation team delivers a precise, code-compliant setup from start to finish. We don’t simply drop a unit outside and call it done — every installation begins with a proper Manual J load calculation to ensure the heat pump we recommend is perfectly sized for your home’s square footage, insulation, and window layout.

One of the most common questions we hear from Mokena homeowners is whether a heat pump can handle Illinois winters. The short answer is yes — with the right equipment. Modern cold-climate heat pumps maintain strong heating output even when temperatures drop well below freezing, making them far more capable than older models homeowners may remember.

For homeowners who want an extra layer of protection against Chicagoland’s harshest cold snaps, we frequently install dual-fuel (hybrid) systems that pair a heat pump with a gas furnace. The heat pump handles the majority of heating and cooling loads efficiently throughout the year, while the furnace kicks in only when temperatures drop to the point where supplemental heat makes economic sense.

Today’s heat pumps are rated using SEER2 and HSPF2 efficiency metrics, and high-efficiency models can dramatically reduce both your heating and cooling costs compared to older HVAC equipment. When you choose TemperaturePro for your installation, we’ll help you identify models that may qualify for federal tax credits under the Inflation Reduction Act as well as any local utility rebates available to Will County homeowners.

Unlike a furnace that only runs in winter or an air conditioner that only runs in summer, a heat pump operates year-round — which means it accumulates wear at twice the rate of a single-function system. Regular maintenance isn’t optional for heat pump owners; it’s the difference between a system that lasts 15 years and one that fails in year eight.

A heat pump is an all-in-one heating and cooling system that moves heat rather than generating it from scratch. In summer, it works like a traditional air conditioner — extracting heat from the air inside your home and releasing it outdoors through a refrigeration cycle. When winter arrives, the process reverses: the system pulls available heat energy from the outdoor air and transfers it inside to warm your home.

This reversing function is controlled by the reversing valve, one of the key components our technicians inspect during every maintenance visit. Because heat pumps move existing heat instead of burning fuel to create it, they can deliver significantly more heating energy per dollar of electricity consumed compared to electric resistance heating — often making them the most cost-effective comfort solution for Mokena homeowners.
