There are a few telltale signs that your furnace or air conditioner needs repair:


  • It’s 15-20 years old (or older)
  • Blows out cold air
  • The pilot light is yellow instead of blue
  • Your energy bill spiked

Air Conditioner

  • It’s 15-20 years old (or older)
  • Blows out warm air
  • There’s ice on the unit
  • It squeaks or grinds when it runs
If a repair is too expensive or too dangerous to make—or if the air conditioner or furnace is simply too old to fix—that’s when we recommend replacing it. Don’t worry, though—the experts at River City can help you every step of the way, from measuring your home and laying out your most cost-effective replacement options to the actual installation.
Yes! For the best possible performance and energy-efficiency, your furnace and air conditioner should be the appropriate size for your home. If your unit is too small, it will cycle constantly to reach your desired temperature. This adds stress on the HVAC system and can lead to frequent breakdowns. If your unit is too big, it will turn on and off too frequently to maintain your ideal comfort levels, which can drain your wallet and your unit’s performance.
We recommend scheduling annual HVAC maintenance. It helps your unit run efficiently for longer and is an opportunity to catch issues before your system fails.
No ductwork, no sweat. Our expert techs specialize in more than just central air conditioner repair—we can also install ductless split systems to keep your home comfortable all year long. These units are specifically designed for hard-to-heat/cool areas or additions.
Having inconsistent temperatures from room to room can be frustrating. Fortunately, there are a few things you can do to heat and cool your home more evenly:

  • Switch your fan setting to “ON” so it constantly circulates air
  • Consider a zoning system—this lets you control temperatures room by room instead of heating and cooling the entire house
  • If you have manual dampers, adjust them to manually control airflow according to your comfort needs
Closing air vents actually does more harm than good. Your furnace and A/C are designed to keep a certain amount of air flowing through your home. So if you close an air vent, static pressure increases and puts more stress on your system. This can lead to motor failure and system breakdowns. If your goal is to reduce energy costs, consider a zoning home comfort system, which can heat and cool areas on an individual basis.
Perhaps the best way to conserve energy is to not blast heat in the winter and A/C in the summer, but we know that’s not always going to happen. To help save money, we recommend these tips:

  • Schedule routine maintenance
  • Change your air filters when necessary
  • Seal drafty doors and windows
  • Use a Wi-Fi-enabled thermostat to monitor your comfort and energy usage
  • In the summer, keep the curtains closed to block off the sun’s warmth—in the winter, keep them open to let the natural warmth in
There are several simple reasons why your thermostat isn’t showing anything. These include dead batteries, a tripped circuit breaker, and a triggered safety switch. Check these things, and if the problem isn’t solved, there may be a deeper issue behind it. Know that the experts at River City are always eager to help when you need it.
