Heating Repair

Is your furnace operating as it should be? If not, it’s best to take care of heating and cooling problems sooner rather than later, for cost, safety, and convenience. Here are a few of the most common heating repair problems we get called out for:

  • Strange smells. Unless you’re certain it isn’t gas, this one demands caution and an immediate call to professionals (right after you step outside and call the gas company first).
  • Strange sounds. If your heating is making unusual sounds, whatever they may be, it’s almost always indicative of a problem that’s going to get worse.  
  • Constant cycling or running. As with an AC, any heating system that starts running all the time or constantly cycling on and off has something wrong with it (or the thermostat controlling it).
  • Blows cool air. If your heat isn’t pushing heat, it clearly needs professional attention — it’s just a fan at that point!
  • No airflow. If you’re getting heat at the unit, but it’s not coming through your ducts, this can be because of obstructions, major duct leaks, or a dead motor.
  • Energy bills going up for no reason. If the energy bills are going up without the weather getting colder, it’s time to call our team for repair.  
  • Pilot light problems. Your pilot light shouldn’t change, flicker with impurities, or go out constantly. If it does, call us!
  • Poor air quality. It’s a bad sign when your heating system starts pushing unclean air, even if it’s just a mild difference in air quality.

AC Repair

Is your air conditioner failing to cool your home, behaving strangely, or driving up your bills? It’s important to figure out quickly whether you need AC repair, because the longer you wait, the more likely it is that your problem will worsen. Here are a few symptoms of an AC in distress:

  • The air coming from your AC isn’t cold. If your air conditioner isn’t blowing cold, you need repairs — even if it starts working again later (likely when frozen evaporator coils thaw).
  • The air isn’t blowing at all. This might be a clogged filter, easily fixed with a replacement, but otherwise could point to duct problems or a dead fan.  
  • Increased energy bills. If your power bills go up without you using more air conditioning, it’s time to call a pro.
  • Constant running or constant cycling. Both of these behaviors can point to a variety of problems, like thermostat issues, a wrongly sized unit, or other component failures.
  • Leaking refrigerant or condensation. Your refrigerant should stay inside your air conditioner, and condensation shouldn’t be forming and dripping where it can cause problems.
  • High humidity. Your air conditioner should be reducing humidity naturally as it operates; if your home feels humid despite this, it might be a sign of something wrong.
