Small HVAC problems quietly  build up. Then you get blindsided.

A cold house. An AC that won't keep up. A bill that keeps climbing. These signs are easy to put off until the heat or cold turns a manageable problem into an urgent decision.

 Then you're asked to choose between repair and replacement before you even know what failed.

You shouldn't have to become an HVAC expert to make a good call about your own house.

Get out of the HVAC guessing game.

Tell Liberty what your system is doing. We'll inspect it, explain what we find in plain language, and lay out the next step. You stay in control of the decision.

“Jason arrived within 45 minutes and quickly diagnosed the problem. Thankfully, he had previously installed a drain pan and wet sensor on my furnace. That sensor shut down the A/C when water was detected, preventing what could have been significant flooding on my first floor.”
Mary P. — Liberty Heating & Cooling Customer

Our Services

What does your home need?

Every visit ends the same way: you know what we found, what your options are, and what each one costs. Then you choose.

Air Conditioning

Air Conditioning

Repairs, replacements and seasonal tune-ups for central AC and heat pumps. If your system is struggling, we'll tell you whether it's a fixable problem or a system near the end of its life — and we'll show you how we got there.

Heating & Furnaces

Heating & Furnaces

Furnace and boiler repair, replacement and pre-season inspection. Most heating failures announce themselves months ahead if someone's looking. We'd rather find it in October than get the call in January.

Air Filtration Systems

Air Filtration Systems

Air purifiers, humidifiers, dehumidifiers and ventilation. Worth doing when there's a reason for it — dust, dry winter air, someone in the house who notices. We'll tell you honestly if you don't need it.

Our most-requested services include furnace repair and heating installation, AC repair and installation, heat pump installs, indoor air quality systems, annual HVAC maintenance, and 24/7 emergency HVAC repair across the Pittsburgh metro.

"Jason has been my 'go to' guy for all of my heating and cooling issues. He installed our air conditioner quickly and at a good price. He is quick to respond and has replaced several parts on our furnace preventing us from having to get a whole new unit. He is very knowledgeable and explains the problem so my wife and I can easily understand. I would recommend Jason's company to anyone as they always do a fantastic job."

"We scheduled our furnace maintenance with Liberty, and everything went well. The technician was professional, and very nice. He performed the maintenance, answered a question I had about upgrading our AC, and priced out a chimney lining for us. I definitely plan on using them for our future Heating and Cooling needs."

— Ricardo T.

"We are so pleased with Jason & his team! They replaced our furnace with just a few days notice. They are very knowledgeable & very polite. They cleaned up everything! The furnace is wonderful! Keeps the house toasty! Jason returned on a warmer day to install the chimney liner. He had a heck of a time, but got the job done!! Thank you to everyone at Liberty Heating!!"

"Jason and his team were great to work with. We needed a new AC unit and ended up replacing our very old furnace at the same time. The prices were very reasonable compared to other estimates we received, and everything has been working well."

Repair or replace? Start with these questions.

A single formula can't tell you which choice fits your home. Use these questions when you discuss your options.

  • What failed, and what would a repair address?
  • Has this system needed repeated repairs?
  • How well does it heat or cool the rooms you use?
  • How do the repair and replacement options compare in cost, scope, and warranty?

Bring your system's age and any recent repair information if you have it. You don't need all the answers before you call.

Common Questions

Frequently Asked Questions

Have a question about your HVAC system? Find answers to common questions below.

We recommend checking your filter monthly and replacing it every 1-3 months, depending on usage, the type of filter, and whether you have pets or allergies. A clean filter improves efficiency and air quality.
Common causes include a dirty air filter, blocked condenser unit, low refrigerant levels, or a malfunctioning thermostat. If cleaning the filter doesn't help, it's best to call a professional for a diagnostic.
Most well-maintained HVAC systems last between 15 and 25 years. Furnaces tend to last a bit longer than air conditioners or heat pumps. Regular maintenance is key to maximizing your system's lifespan.
Programmable thermostats can save you up to 10% a year on heating and cooling by automatically adjusting the temperature when you are away or asleep, reducing unnecessary energy consumption.
No. We'll tell you the diagnostic charge when you book the repair visit, before anyone comes out. Free estimates advertised on this site apply to new heating or cooling equipment.
