Air Conditioner Unit Replacement – What to Expect

Our AC replacement services help homeowners determine whether their AC unit can be repaired and, if not, lay out a clear plan to replace the faulty system quickly. Once we know there’s no way to fix the old unit, your technician will highlight a range of replacement options, from similar AC replacements to energy-efficient air-source heat pumps. 

We’ll provide a detailed estimate of the cost of replacing the air conditioner and a clear timeline for when work will start and end. 

Air Conditioner Installations – What to Expect

Keep your cool with simple, affordable air conditioning installation services. In most cases, our installation customers are adding central air conditioning for the first time, which may include additional work to connect the new system to the home’s ductwork and filtration system. 

We also install ductless mini-split heat pumps for homeowners who do not wish to have ductwork installed. 

Types of Air Conditioning Units We Install

As a national leader in home cooling, your local One Hour Heating& Air Conditioning is ready to replace or install any residential air conditioning system on the market, including:

  • Central air conditioning
  • Air-source heat pumps
  • Ductless mini-splits
  • Wall air conditioning units
  • Window air conditioning units

No two homes are alike. That’s why our technicians take time to evaluate your home and make informed recommendations on the most cost-effective ways to replace your heat pump or AC unit. What you had may not be what you need! 

Six Signs That It’s Time to Replace Your AC

Even well-maintained air conditioning systems have a functioning lifespan. Depending on the quality of the unit, the regularity of maintenance, and the frequency of use, most AC systems last 10-20 years. In hotter, more humid climates, systems tend to last shorter periods. 

These are the six most common signs you may be ready for a new AC, mini-split, or heat pump: 

  1. Poor performance – Worn-out and malfunctioning ACs and heat pumps don’t cool as consistently or efficiently as they once did. If you notice warm air coming from vents after your AC unit or heat pump runs for a few minutes, it requires a professional inspection. 
  2. Insufficient airflow – Older units may not consistently circulate air to all parts of the home, resulting in hot or cold spots and higher energy bills. 
  3. Frequent cycling – Also known as short-cycling, this occurs when the AC or heat pump turns on and off constantly, often for just a few minutes at a time. Frequent cycling adds wear and tear, increases energy expenses, and fails to keep your home comfortable. 
  4. Structural issues – Whenever you spot physical damage to an AC or heat pump, or hear odd sounds and humming (often caused by structural issues), call the pros. Common problems include corrosion, water leaks, exposed wiring, and damaged or obstructed vents and coils. 
  5. Constant repairs – If your AC system requires frequent spot-fixes, it’s time to make a change. Replace the AC instead of relying on repeated service calls to keep your home cool.
  6. Higher energy bills – Older AC units are less efficient than today’s models and may use even more energy as they age due to worn parts. If you notice a spike in our energy bill, it might be time for an AC upgrade! 

If you’re experiencing any of these problems, contact your local One Hour Heating & Air Conditioning to schedule an inspection!

AC Installation and Replacement FAQs

View All FAQs

  • <p>What is the cost to install central AC?&nbsp;</p>

    Installing a central heating and cooling system could cost anywhere from $2,500 - $25,000 or more depending on several factors including: the size of the system needed (measured in tonnage), type of system (straight air vs heat pump), system configuration (split system, mini-split system, packaged system), the efficiency of the system (measured in SEER rating, the higher the SEER rating the higher the initial cost), the complexity of the installation (jobs that are more complicated take longer and cost more), whether you need new ductwork or duct modifications can add to the overall cost of your project.  Having an HVAC professional perform a proper heat load calculation on your home and inspect the ductwork to ensure it is adequate will help you choose the right system for both your home and your budget. 

  • <p>How do you Install a Mini Split AC?&nbsp;</p>

    Installing a mini split AC involves mounting the indoor air handler, placing the outdoor condenser unit, drilling a small hole through the wall for the refrigerant line, and connecting the electrical and drainage components. It also requires vacuuming the lines and charging the system properly. Because it involves electrical work and refrigerant handling, professional installation is highly recommended to ensure safety, performance, and code compliance.

  • <p>Can I upgrade to a more energy-efficient AC system?</p>

    Yes, newer AC systems offer higher SEER ratings, improved comfort, better indoor air quality and large savings. With an improved system, you can expect lower energy bills and maintenance costs, as well as potential tax incentives and an increased home value. 

  • <p>Why is my AC not blowing cold air?</p>

    If your AC isn’t blowing cold air, it could be a sign that the system is old, low on refrigerant, or has a failing component like the compressor. In some cases, repair may solve the issue, but if your unit is over 10–15 years old, it may be more cost-effective to consider replacement for better performance and efficiency.

  • <p>Do you provide same-day AC maintenance?</p>

    Yes, One Hour Heating & Air Conditioning offers same-day emergency HVAC services, including AC maintenance. Technicians are available 24/7 and arrive fully equipped to handle most maintenance needs on the spot.

  • <p>What size AC unit do I need for my house?</p>

    The size of the AC unit you need is measured in tons  1 ton = 12,000 BTUs (British Thermal Units) and depends on your home’s square footage, type of construction, insulation values, ceiling heights, windows, and climate. A professional HVAC load calculation will provide the most accurate sizing for both comfort and efficiency. An improperly sized system can lead to increased energy usage, an uncomfortable home, and even decrease the system's lifespan. 

  • <p>How long does AC installation take?</p>

    AC installation typically takes 4 to 8 hours for most homes. The timeline can vary based on the system type, home layout, and whether additional work, like ductwork or electrical upgrades, is needed.

  • <p>Can I install an AC unit myself?</p>

    While it's possible to install smaller units like window or portable ACs yourself, it’s not recommended for larger systems. Central AC units and ductless mini-splits require professional installation to ensure proper sizing, safe electrical and refrigerant handling, and compliance with local codes. Attempting to install these systems on your own can lead to safety risks, reduced efficiency, and voided warranties.

  • <p>Why is my AC leaking water?</p>

    Your AC may be leaking water due to a clogged condensate drain line, a dirty air filter, low refrigerant levels, or a damaged drain pan. These issues can cause condensation to build up and overflow. A professional technician can diagnose and fix the problem to prevent water damage.

  • <p>How long will my new AC last?</p>

    A new AC system typically lasts 12 to 20 years with proper maintenance. Factors like usage, climate, and routine care can affect its lifespan. Regular tune-ups and filter changes help extend performance and efficiency.

  • <p>Should I repair or replace my current AC unit?</p>

    If your AC is over 10 years old, needs frequent repairs, or isn’t cooling efficiently, replacement is often more cost-effective than continued repairs.

  • <p>How long does it take to cool a house after AC repair?</p>

    After an AC repair, it typically takes a few hours to cool your home, depending on the outside temperature, home size, and system efficiency.

  • <p>Is AC replacement worth the investment?</p>

    Yes, replacing your AC can be a smart investment—especially if your system is 10–15 years old. Older units tend to be less efficient and need more repairs. A new system can improve comfort, reduce energy costs, and boost your home’s value.

  • <p>Will my home be without AC during replacement?</p>

    Briefly, yes. The technicians will need to disconnect your air conditioner to install and connect your new system. Most AC replacements can be completed in less than 1 day, but more difficult replacements can take longer.

  • <p>What maintenance is required after replacement?</p>

    After AC replacement, schedule annual professional maintenance to keep your system running efficiently and maintain your warranty. This includes cleaning coils, checking refrigerant levels, inspecting components, and changing filters regularly.

  • <p>What&rsquo;s included in a professional AC maintenance visit?</p>

    A professional AC maintenance visit typically includes inspecting and cleaning coils, checking refrigerant levels, tightening electrical connections, testing system performance, lubricating moving parts, and replacing or cleaning the air filter. These steps help improve efficiency, prevent breakdowns, and extend the life of your system.

  • <p>Can I perform any AC maintenance myself?</p>

    Yes, you can perform basic AC maintenance tasks yourself, such as replacing air filters every 1–3 months, clearing debris around the outdoor unit, and keeping vents clean and unobstructed. However, professional maintenance is still important for inspecting internal components and ensuring optimal system performance.

  • <p>Will maintenance help lower my energy bills?</p>

    Yes, regular AC maintenance can help lower your energy bills by improving system efficiency. A well-maintained unit uses less energy to cool your home, which reduces wear and tear and helps avoid costly repairs.

  • <p>How do I prepare my home for AC installation?</p>

    To prepare for AC installation, clear the area around where the indoor and outdoor units will go, ensure easy access to your electrical panel and thermostat, and secure pets for safety. It’s also helpful to move furniture or valuables that may be in the technician’s work path.

  • <p>Can I upgrade to a smart thermostat with my new AC?</p>

    Yes, you can upgrade to a smart thermostat with your new AC system. Most modern units are compatible and a professional can ensure proper installation and setup for maximum efficiency and control.

“Exceptional Service and Support – Highly Recommend! I can’t say enough good things about One Hour Heating and Air Conditioning! I first reached out to them for an emergency air conditioning issue, and even though it was in the middle of the night, Britney took my call with such warmth and professionalism. It was a long process, but she really set the tone for the excellent service to come. Jordan, the technician who arrived to assist, was beyond kind and patient. He helped us with the installation of a new air conditioner, and we were really impressed with his attention to detail. The company also provided some great discounts, which made the whole experience even better! Unfortunately, we encountered a manufacturer issue with the unit, but the team was incredibly prompt and responsive in addressing it. They made multiple follow-up visits to ensure everything was working properly, and each time they arrived, they were professional, courteous, and on-time. I was especially impressed by how they took the time to clean up after the installation and repairs, leaving no mess behind. What truly stands out is their commitment to making sure everything was working as it should. A week later, they even checked in to ensure we were still satisfied. Their honesty, excellent customer service, and fair pricing make them a company I would highly recommend to anyone. —-Dorothy”
