AC Replacement

Your Air Conditioner Just Stopped Working

Full air conditioning system replacement services available now

When your air conditioning system stops cooling your home or runs constantly without dropping the temperature, you face a decision between continued repairs and a full replacement. If your unit is more than twelve years old or the repair estimate approaches half the cost of a new system, replacement often makes more sense than another temporary fix.


Mid-State Heating & Cooling provides complete air conditioning system replacements when your current equipment is broken beyond repair or when ongoing repair costs no longer justify keeping the old unit running. You receive a new system designed to cool your home efficiently, installed by technicians who handle everything from removing the old equipment to testing the new unit under load. Financing is available if you prefer to spread the cost over time rather than paying upfront.


If your system has failed and you need to know whether replacement is the right call, contact Mid-State Heating & Cooling to schedule an assessment.

What Happens During a Full System Replacement

The replacement process begins with removing your existing air conditioning equipment, including the indoor evaporator coil and outdoor condenser unit. Technicians disconnect refrigerant lines, electrical connections, and ductwork attachments before lifting out the old system and preparing the installation area for the new equipment. You receive a system sized to match your home's cooling load, not simply the same capacity as the unit being removed.


Once the new system is installed, you will notice consistent cooling in every room, quieter operation, and lower monthly energy bills compared to running an aging unit that struggled to maintain temperature. The new thermostat responds faster, and the system cycles on and off at appropriate intervals instead of running continuously or short-cycling.


Mid-State Heating & Cooling tests the system under full operating conditions before leaving your property, checking refrigerant levels, airflow, and electrical draw to confirm everything meets manufacturer specifications. Because they are available around the clock, you can arrange replacement work at a time that fits your schedule, even if your system fails on a weekend or holiday.

Questions homeowners ask before replacing their AC

Most people want to know how long the work takes, what the new system will look like in their home, and whether financing makes sense for their situation. These are the questions that come up most often.


  • How do I know if my AC needs replacement or just repair?
  • If your system is over twelve years old, requires frequent repairs, or the latest repair estimate is more than half the cost of a new unit, replacement usually makes more financial sense. Mid-State Heating & Cooling can evaluate your current system and give you a clear recommendation based on its condition and your cooling needs.


  • What does the replacement process involve?
  • Technicians remove your old indoor and outdoor units, disconnect all refrigerant lines and electrical connections, then install the new system and test it under full load. The work typically takes one full day depending on the complexity of your ductwork and electrical setup.


  • Why would I finance an AC replacement instead of paying upfront?
  • Financing allows you to get a new system installed immediately without depleting savings, especially if your current unit failed unexpectedly. You spread the cost over manageable monthly payments while benefiting from lower energy bills right away.


  • What will be different after the new system is installed?
  • You will notice rooms cool down faster, the system runs quieter, and your thermostat holds the set temperature without constant adjustments. Monthly energy costs typically drop because new systems use less electricity to produce the same amount of cooling.


  • When is the best time to schedule a replacement?
  • If your system has already failed, the best time is immediately to restore comfort in your home. Mid-State Heating & Cooling is available around the clock, so you can arrange installation even if the failure happens on a weekend or during a holiday.


Mid-State Heating & Cooling handles the entire replacement from start to finish, including hauling away your old equipment and making sure the new system cools your home the way it should. If your air conditioner has stopped working or repairs are piling up, reach out to discuss replacement options and financing.

With the first hard freeze out of the way, it's safe to say that all of our heating systems are in full swing this season. Unfortunately, we are far from the end of the cold weather. Is your furnace ready to get you through the cold days ahead? Too often, homeowners wait until something goes wrong with their system to call an HVAC service technician out. However, every HVAC system requires regular maintenance to ensure it is performing properly and will continue to. This means you should not only call your technician when something goes wrong; If you are still playing defense with your maintenance instead of making offensive moves, it's time for a change.

Mid state heating and cooling always do a great job. They installed our AC three years ago and it has worked beautifully. Called for maintenance - they confirmed and showed on time. Jamie the technician was so knowledgeable and patient- and answered all our questions and then some. Very positive experiences!

Mid State intalled an air conditioner and air handler for me during covid. I was not able to close the permit with the town for 2 years following covid. Once I was able to get it inspected, It failed inspection for something minor. Mid state responded out within 3 days and corrected the issue.

Mid-State replaced the two-zone heat/AC in my house with high efficiency Trane units. I was very happy with their work, professionalism, and price. They hooked up nest thermostats and showed me how to used them and also walked me through the state rebate process to get thousands of dollars back for installing high efficiency units. I'm excited to see how much my utility bills drop now. I couldn't be happier, highly recommended!!

I had Mid-State install a Generac standby generator. It was the most professional job done in my house in the 22 years I have lived here. They came at the promised time, finished on time and when they left, my house looked as if no one was ever here. I cannot recommend them high enough

Jack came right out the next day after we called and met with my family to replace our entire HVAC system he was extremely nice and didn't push us into buying anything we didn't want. We had no working heat so he had his guys show up the very next morning before 9 am!

I cannot say enough good things about this company! My furnace stopped working in the middle of a 30 degree night - I called Midstate around 2am, not expecting anyone to answer, but to my surprise, I actually spoke to a live representative who took the time to listen & understand my problem.

They installed a new furnace and water heater during the recent cold weather. I checked the price against 2 other people quickly as the temperature was dropping! They appeared in line with other reputable companies. The furnace was all that had actually stopped working, but they noticed some water drops on the bottom of the water heater and it was 15 years old so I was reactive on the furnace and proactive on the water heater.

We have used Mid-State multiple times for various reasons. Each time their service has been nothing short of amazing. Their techs were prompt courteous, and most importantly knowledgeable. They quickly resolved issues pertaining to both gas furnaces and heat pumps. I can't recommend them enough. A++ service!! And also at a fair price.

Mid state replaced my entire heating and cooling system at my house back in January 2015. They also replaced my water heater. The crew was very courteous and polite, I could not say that much about their manager Blake?!, but the worker were great people. The office lady Rhonda was fantastic with us. The Owner Bryan is a good men and wants the best for his customer. We did hit a speed bump at the beginning withe the manager, but after a visit from the owner Bryan, it was fixed immediately as his concern was the comfort of his customer. Overall good experience, I do recommend them.

Highly recommend Mid-State above any other Heating & Cooling Service I have used in the past. They are extremely responsive, all of their employees are professional from the office workers to the people who come and actually do the work in your home, and they are very thorough in their work. Additionally, when compared to other companies, I found their prices to reasonable and fair and the product that they use to be top of line.

've been pleased to have Mid-State work in my home each time I needed HVAC work since 2010. Every person I've met from Mid-State has been considerate and knowledgeable. The owner, Brian, is a gentleman and makes certain his customers are satisfied.

My wife Sandy and I began reaching out to heating and cooling contractors about six months ago after our central air conditioning unit began to fail. In the process we became aware of The New Jersey Home Performance with ENERGY STAR program that offered significant rebates and favorable loan terms for home energy projects that met their criteria. Their website also listed certified and participating contractors that were qualified to do the actual work. We called and met with several of these contractors and chose Mid-State to conduct the project.

After trying several HVAC companies and not liking something about all of them, about 10 years ago I tried Mid-State and have never needed to consider anywhere else. They are responsive and do quality work. Today Jamie came to do annual maintenance, and was professional and thorough. I completely trust Mid-State for all my HVAC needs.

This service call was for the yearly AC maintenance as part of the contract. I have been quite pleased over two years of working with this maintenance arrangement, since I moved to a new residence. The tech was Jamie Patterson who continued with his usual professional, helpful, and friendly behavior.
