Signs You Need Air Conditioning Repair

Is your air conditioner acting strange? Have you noticed a change in your system or comfort, but you’re unsure if it warrants repair? Repairing issues at the first sign of malfunction mean avoiding breakdowns and more expensive repairs later.

Keep an eye out for these signs that you need air conditioning repairs:

  • Low or no airflow
  • Warm air when your thermostat is set to cool
  • Strange sounds or smells from your air conditioner
  • Leaking refrigerant or condensate
  • A malfunctioning thermostat
  • Rising energy bills without a change in usage

When you need AC repair, we offer same day service available seven days a week. If you have an emergency at hand that leaves you without AC, we’re available for emergency repairs as well.

Air Conditioning Installation & Replacement

Eventually, every air conditioner needs to be replaced. When that time comes, work with Len The Plumber Heating & Air to find the right system for your needs. We’ll accurately size, install, and test your AC replacement so you can enjoy all the benefits of a new unit, including:

  • Improved energy efficiency
  • A more comfortable home
  • Fewer breakdowns
  • Improved home value
  • And more!

Alternative Cooling Systems We Install

In addition to traditional central AC systems, the team at Len The Plumber Heating & Air installs and services alternative cooling systems, including:

  • Ductless mini-splitsInstead of ductwork, this system uses small refrigerant lines that connect indoor air handlers to an outdoor unit. You can control the climate of individual zones because each air handler has its own thermostat.
  • Heat pumpsThis system works similarly to central AC but has a reversing valve so it can heat your home in the winter too. Consider a heat pump for energy-efficient heating and cooling.
