Our Installation Process

  1. Request a Free Estimate

    Start with a free air conditioning system installation or replacement estimate. Call AVS at Virginia 703-457-9028 or Maryland 301-686-7129, or send an online request with your ZIP code and project details.

  2. Receive an Arrival Call

    After we receive your request, an AVS team member will contact you to arrange a visit at a time that works for you. Share any access needs and let us know whether your existing system has stopped working.

  3. View Product Options & Estimated Prices

    During the visit, our technician will discuss your cooling needs, rooms that stay hot, humidity concerns and budget. We will review suitable options and provide a clear installation estimate with upfront pricing so you can decide what works for your home.

  4. Installation

    Once you approve the estimate, we schedule your air conditioning system installation at an agreed time. In most cases, installation is completed within 24 hours of confirmation; your actual schedule depends on equipment availability, project scope and any permit or inspection requirements. Confirm the schedule for your home when approving the estimate. Before installation, we discuss equipment access and the agreed project scope. Confirm removal, duct or electrical modifications, drainage, permits, startup checks, cleanup and the system walkthrough in your proposal. Ask how airflow, controls and cooling operation will be checked. Permit requirements depend on your address and scope. Montgomery County requires mechanical permits for covered HVAC replacements. Confirm who handles the application and inspection for your project. Montgomery County permit guidance.

  5. Give Us Feedback

    After your air conditioning system is installed, tell us how the visit went and raise any questions about the new system. Your feedback helps AVS improve its service and understand any concerns that need attention. Request a Free Installation Estimate

Is It Time to Consider AC Replacement?

You may be ready to compare replacement options if:

  • Repairs are becoming a recurring expense.
  • A major component has failed and the remaining equipment also has problems.
  • Your home stays uncomfortable despite addressing maintenance and repair issues.
  • You are renovating or changing how rooms are used.
  • You want to compare your current system with newer comfort and efficiency options.

These are reasons for an evaluation, not automatic reasons to replace the AC. Uneven temperatures can also involve ductwork, insulation or airflow. Identifying those issues before installing new equipment helps avoid carrying the same discomfort into the next system. Request a Free Installation Estimate

 

Would a Repair Solve the Problem?

Start with the fault and the condition of the whole system. A targeted repair may be reasonable if the problem is isolated and the equipment otherwise meets your needs. A replacement comparison becomes more useful when you face repeated failures, a substantial repair or unresolved comfort problems. Ask for both scopes: what the repair would correct, and what a replacement would change. Include warranty coverage, component compatibility and any required supporting work in the comparison. If the cause of the failure is still unclear, start with an AC repair diagnosis.

 

Choose an AC for Your Rooms, Humidity and Budget

A new air conditioner should be selected for the home it will serve. Matching the size printed on your old equipment is not a complete sizing assessment. If you are installing central air for the first time, the project may need new ductwork, electrical connections and equipment locations. A replacement begins with an existing system, but its ducts and connections still need assessment. Tell AVS which situation applies so your estimate reflects the full project. Discuss the rooms that overheat, temperature differences between floors, indoor humidity and where equipment noise bothers you. A central air replacement also needs to work with the indoor coil, blower, thermostat and duct system. High-efficiency AC options may offer different operating stages, sound levels and comfort controls. Ask how those features address your priorities, and compare the installed cost. An efficiency rating alone does not predict your future utility bill. When comparing equipment quotes, SEER2 is the cooling-efficiency rating to look for. Compare the matched system rating alongside installation scope, comfort features and price; it does not guarantee a particular utility bill. Trane explains current HVAC efficiency ratings.

 

What Should the Home Assessment Cover?

For your AVS estimate visit, have your current equipment information and comfort concerns ready. The assessment and proposed scope should address:

Cooling load and system sizing. Ask how the recommended capacity accounts for insulation, windows, layout and other features that affect cooling demand. Discuss a Manual J load calculation where appropriate or required.

Ductwork and airflow. Identify whether the existing ducts and return-air pathways can support the proposed system and whether repairs or modifications are needed.

Matched equipment. Confirm the intended combination of outdoor unit, indoor coil and air-moving equipment. A partial replacement needs a compatibility review.

Electrical supply and controls. Establish whether existing circuits, disconnects and thermostat controls suit the selected equipment. Drainage and placement. Review condensate disposal, equipment access and outdoor-unit placement before the installation scope is finalized. The point of this assessment is practical: you should know which existing components can remain and which parts of the installation need additional work.

 

What Should Your AC Installation Estimate Include?

Compare complete scopes, not only equipment names. Before accepting an AVS proposal, ask for the following items to be identified in writing:

  • Proposed equipment, capacity, efficiency ratings and indoor/outdoor combination.
  • Removal and disposal of the equipment being replaced.
  • Included duct, electrical, refrigerant-line, drain and thermostat work.
  • Permit and inspection responsibilities, with associated charges.
  • Startup checks, system testing and the final walkthrough.
  • Equipment warranty, any labor coverage and registration responsibilities.
  • Work excluded from the price, allowances and optional upgrades.

Do not assume a new electrical panel, extensive duct replacement, finish repairs or unrelated construction is part of a standard installation price. Confirm each item that applies to your home. Request a Free Installation Estimate

 

Central AC or a Heat Pump?

Central AC provides cooling and can be paired with a compatible furnace. A heat pump can provide both cooling and heating, making it worth discussing when you are evaluating the wider heating and cooling system. If your furnace is also approaching a major repair, compare replacing the AC alone, replacing the AC and furnace together, or considering heat pump installation. Equipment condition, compatibility, fuel source and your home’s needs determine which options deserve a quote.

 

What Affects AC Replacement Cost?

AC replacement cost in Northern Virginia and Maryland depends on equipment selection and the work needed to install it properly. Capacity, efficiency, operating stages, access and the condition of existing components can all affect the price. A replacement using suitable existing ducts and electrical connections has a different scope from a project that also needs duct modifications, new controls or electrical upgrades. Ask for optional improvements to be priced separately so you can see where your budget is going. Ready to put a price on your project?

Compare Coverage and Payment Options Before You Commit

Ask AVS about the equipment warranty, any installation labor warranty and the maintenance or registration requirements attached to that coverage. Equipment and labor coverage may have different terms. For financing, request the current lender information and compare the payment amount, APR, repayment period and any promotional conditions. A monthly payment should be considered alongside the total purchase cost.

FAQ's

System sizing should reflect the home’s cooling load, layout and airflow requirements. Ask how the recommended capacity was calculated and whether a Manual J assessment is appropriate for your project.

Not always. The furnace’s condition, blower capability and compatibility with the proposed coil and controls matter. Compare the scope and cost of keeping suitable equipment versus replacing both systems.

Ask for a project-specific schedule after the assessment. Access, equipment availability, duct or electrical work and inspections can affect the timeline. Confirm how long cooling is expected to be unavailable.

Not necessarily. Those rooms may also need attention to airflow, duct condition or the home’s insulation. Describe the problem during the assessment so the quote can address its likely cause.

Yes. AVS offers free installation and replacement estimates. A diagnostic visit for broken equipment is a separate service; ask about the diagnostic fee when requesting a repair.
