AC Efficiency Assessments in Aurora, CO

Rising Summer Electric Bills

If your summer electric bills have climbed 15-30 percent or more over the past few years without major changes in usage, your AC is losing efficiency somewhere. The reasons range from cheap fixes (dirty coils, low refrigerant) to expensive ones (failing compressor, leaking ductwork). An efficiency assessment isolates the cause so you can make targeted decisions rather than just replacing equipment that may not be the actual problem.

Comparing Quotes for Replacement

When one contractor recommends a $9,000 replacement and another recommends a $12,000 system, the right answer is rarely either quote. An efficiency assessment gives you objective data about what your existing system actually does and what your home actually needs, letting you evaluate replacement bids on technical merit rather than sales pressure. We routinely tell homeowners they do not need to replace their system at all and explain what targeted service can recover most of the lost efficiency.

Aging System, Uncertain Future

If your AC is 10-15 years old and operating but starting to show its age, you face a planning decision: keep running and budget for emergency replacement, or plan a proactive replacement on your terms. An assessment quantifies your system's remaining useful life and helps you make the right call rather than guessing.

Newly Purchased Home

When you buy a Aurora, CO home, the AC system comes with it, and standard home inspections rarely evaluate AC performance in any meaningful way. An efficiency assessment tells you what you actually inherited so you can budget appropriately for the years ahead.

Comfort Problems Without Obvious Causes

If your system runs but the home is not comfortable, uneven cooling between rooms, humidity that does not drop, certain rooms always warmer than others, the cause is often duct leakage, undersized return air, low refrigerant, or other issues that diagnostic testing can identify objectively.

Our comprehensive assessment evaluates your cooling system across multiple dimensions:

Refrigerant Performance

• High-side and low-side pressures measured against manufacturer specifications
• Superheat and subcool calculations to verify proper charge
• Identification of refrigerant leaks if present
• Refrigerant type documentation (important for older R-22 systems)

Airflow Performance

• Total system airflow measured at the air handler
• Static pressure measurements (indicates ductwork or filter restriction)
• Supply and return airflow at registers
• Blower motor amp draw and capacitor performance

Heat Transfer Performance

• Temperature drop across the evaporator coil (the gold-standard performance metric)
• Approach temperatures at indoor and outdoor coils
• Coil condition (dirt, biological growth, fin damage)
• Refrigerant line set inspection and insulation condition

Ductwork Performance

• Visible duct inspection for leakage, insulation, and sizing
• Supply/return balance evaluation
• Register and grille airflow distribution
• Damper and zone control verification (where applicable)

Electrical and Control Performance

• Capacitor performance against rated microfarad output
• Contactor condition
• Thermostat calibration
• Compressor amp draw and starting characteristics

Documentation and Reporting

• Equipment age, model, and serial number documentation
• SEER/SEER2 rating from manufacturer data
• Estimated remaining useful life
• Written report with findings, recommendations, and cost estimates
• Photographs of relevant findings

After the assessment, you get clear answers to the questions that matter:

• How is your system actually performing versus its rated capacity?
• Where is performance being lost, equipment, ductwork, refrigerant, or installation issues?
• What targeted service could recover lost efficiency (and at what cost)?
• What is the remaining useful life of your existing equipment?
• If replacement is warranted, what size and efficiency rating do you actually need?
• Are there ductwork or installation issues that affect both your current system and any replacement?

Often we find that homeowners who were quoted full replacement actually need a $300 coil cleaning, a $400 refrigerant repair, or a $600 ductwork sealing project, and those targeted fixes recover most of the efficiency they were losing. Other times we find that replacement truly is the right answer, and we can specify the right size and efficiency level rather than letting another contractor oversell or undersize. Either way, you get the data you need to make a confident decision.

AC efficiency assessments typically cost a few hundred dollars. The value comes from what you avoid spending:

• Avoiding unnecessary $8,000-$14,000 replacement when the actual issue costs $300-$1,500 to fix
• Avoiding oversized replacement equipment that costs more upfront and runs less efficiently
• Avoiding repeated refrigerant top-offs when finding and fixing the leak is the right answer
• Identifying ductwork issues that would persist even with new equipment
• Quantifying the value of efficiency upgrades for accurate replacement decisions
• Documenting system condition for insurance, warranty, or real estate purposes

• Certified Carrier Factory Authorized Dealer, the industry's highest dealer credential
• Established in 1998, over 27 years of Colorado HVAC experience
• Trusted by Denver Health, EPA Region 8, NREL, and the Denver Public Library

How much does an AC efficiency assessment cost in Aurora, CO?

MSI's comprehensive AC efficiency assessments typically range from $250 to $500 depending on system complexity and whether ductwork testing is included. The cost is often credited toward any recommended work you have us perform. For homeowners facing major replacement decisions, the assessment cost is typically less than 5 percent of the replacement cost being evaluated.

How is an assessment different from a tune-up?

A tune-up is preventive maintenance designed to keep a working system running well, cleaning, lubrication, basic performance checks, and small adjustments. An assessment is a diagnostic evaluation focused on measuring actual performance against rated specifications, identifying the root causes of performance issues, and producing a written report with recommendations. Tune-ups maintain; assessments diagnose.

Will the assessment include recommendations for repair?

Yes. The written report identifies specific issues found and provides up-front cost estimates for any recommended work. You decide whether to proceed with MSI, use the report for second opinions from other contractors, or simply file the information for future reference. There is no pressure to use us for any follow-on work.

How long does an AC efficiency assessment take?

A typical assessment takes 90 minutes to 3 hours depending on system complexity, the depth of ductwork evaluation, and any unusual configurations. We document findings on-site and deliver the written report within a few days.

Can the assessment tell me whether to repair or replace?

Yes, that is often the primary question we are answering. The combination of equipment age, current condition, refrigerant type, performance metrics, and projected repair costs gives us the information needed to provide a clear, data-driven recommendation.

My AC isn't even broken, why would I get an assessment?

Common reasons even when nothing is obviously wrong: bills have been climbing, you want to know your system's remaining life before it fails unexpectedly, you just bought the home and want to know what you inherited, you are considering preventive replacement, or you want to know whether an efficiency upgrade would actually save you money. An assessment is the answer to all of these.

If you face an expensive cooling decision and want objective data rather than another sales pitch, an AC efficiency assessment is the smartest first step. Call MSI to schedule.
