Most standard AC repairs — like replacing a capacitor, clearing a clogged drain line, or adding refrigerant — are completed within one to two hours. More complex repairs may take longer. Your technician will give you a realistic timeframe once they’ve diagnosed the issue.

A typical new HVAC installation takes one full day — usually four to eight hours, depending on the system type and any additional work required such as duct modifications or electrical upgrades. We’ll confirm the estimated time when we schedule your installation.

Yes! Visit ms-ac.com to book an appointment through our online scheduling portal. You can choose your service type and preferred appointment time right from your phone or computer.

While waiting, check your thermostat settings and confirm it’s in the correct mode. Replace your air filter if it looks dirty. Check your circuit breaker to make sure the HVAC system hasn’t tripped a breaker. If it’s hot, use fans and close blinds to stay comfortable. Don’t try to force a unit to run if it’s making unusual noises — shut it off and wait for us.

Yes, we stand behind our work. We want every customer to be completely satisfied, and we’ll make it right if something isn’t working as it should after we’ve serviced your system. For specific labor warranty terms, please contact us at (775) 843-7930.

New HVAC equipment typically comes with a manufacturer’s warranty on parts — often 5 to 10 years depending on the brand and model, and sometimes longer when the equipment is properly registered after installation. We’ll walk you through the warranty details for any system we install and help you register the equipment.

Our goal is to fix it right the first time. If you experience an issue with a repair we recently completed, call us at (775) 843-7930 and we’ll prioritize getting back out to you. We take our work seriously and want you to have confidence in every repair we do.

Most OEM (original equipment manufacturer) parts come with their own manufacturer’s warranty, and in many cases that coverage passes through to you. We always use quality parts and will let you know what warranty comes with them.

Absolutely. If you have any concerns about your new system — how it’s running, the comfort level in your home, or anything else — reach out at (775) 843-7930 and we’ll address it.

A ductless mini-split system provides heating and cooling without traditional ductwork. It consists of an outdoor compressor unit connected to one or more indoor air handlers mounted on the wall or ceiling. Mini-splits are ideal for home additions, garages, older homes without ducts, or any space where installing ductwork would be difficult or expensive. They’re also very energy-efficient.

A furnace generates heat by burning gas or using electric resistance coils. A heat pump transfers heat from the outdoor air into your home rather than generating it — which makes it very efficient in moderate temperatures. In Reno-Sparks winters, many homeowners pair a heat pump with a gas furnace backup (a dual-fuel system) for the best of both worlds.

A packaged unit is a self-contained HVAC system that houses both heating and cooling components in a single outdoor cabinet. Unlike a split system with separate indoor and outdoor components, everything is in one box. Packaged units are common in homes with limited indoor mechanical space and in commercial applications.

Proper sizing requires a Manual J load calculation, which accounts for your home’s square footage, insulation, window area, ceiling height, and local climate. An undersized system won’t keep up on hot days; an oversized system short-cycles, runs inefficiently, and fails to properly dehumidify. We perform proper sizing assessments before any installation.

SEER stands for Seasonal Energy Efficiency Ratio — a measure of how efficiently an air conditioner or heat pump cools your home over a season. The higher the SEER number, the more efficient the system. Modern systems are required to meet a minimum SEER threshold, while high-efficiency units can reach 20 SEER or higher. A higher SEER costs more upfront but saves on energy bills over time.

A single-stage system runs at full capacity (100%) until your home reaches the set temperature, then shuts off. A variable-speed system operates at many different capacity levels — 40%, 60%, 80%, or 100% — depending on conditions. Variable-speed systems are quieter, maintain more consistent temperatures, dehumidify better, and use less energy overall.

A two-stage furnace runs at full capacity on the coldest days and at a lower setting (typically around 65–70% capacity) on milder days. This allows it to run longer at a lower rate, which improves temperature consistency and humidity control compared to a single-stage furnace while using less fuel on most days.

With proper maintenance, most central air conditioners last 12–15 years and furnaces can last 15–20 years. Ductless mini-splits often exceed 20 years. Regular tune-ups — like the ones included in our M&S Maintenance Plan — are one of the best ways to maximize the life of your equipment.

A dual-fuel system pairs an electric heat pump with a gas furnace. The heat pump handles heating efficiently when outdoor temperatures are moderate, and the gas furnace kicks in automatically when it gets very cold. In the Reno-Sparks area — where we have cold winters but plenty of mild days — a dual-fuel system can be a very comfortable and cost-effective setup.

On installation day, our technicians remove and dispose of your old equipment, install the new system, connect it to your existing ductwork and electrical or gas supply, test the system thoroughly to confirm everything is running correctly, and walk you through operating your new thermostat. We treat your home with care and clean up completely before we leave.

In most cases, yes — HVAC installations typically require a permit from your local building department. We handle the permit process for you as part of the installation, ensuring the work meets local building codes and protecting you as a homeowner.

Most installations are completed in a single day, and we work efficiently to minimize the time your system is offline. If you’re concerned about comfort on the day of installation — especially in extreme temperatures — let us know when scheduling and we’ll discuss your options.

We perform a thorough assessment of your home, including its size, insulation, window placement, existing ductwork, and your comfort goals and budget. We then recommend the system that provides the best combination of comfort, efficiency, and value — and we always present multiple options so you can make an informed decision.

We handle the removal and proper disposal of your old equipment. Old refrigerants must be recovered and disposed of in compliance with EPA regulations, and we make sure that’s handled correctly. Please contact us at (775) 843-7930 if you have specific questions about disposal.

Please make sure there’s clear access to your outdoor unit location, attic, mechanical room, or wherever the system is being installed. Move any furniture or stored items away from the work areas, and have a trusted adult home throughout the day. Your technician will let you know if there’s anything else to prepare.

In some cases you can replace just the outdoor unit, but it depends on the age and compatibility of your existing indoor components. Mixing old and new components can create efficiency and reliability problems, and manufacturers may not honor the warranty on a mismatched system. We’ll evaluate your existing equipment and give you an honest recommendation.

Standard HVAC installations are relatively low-disruption — our team works in equipment rooms, attics, or outdoors. You’ll hear noise from the work and be without heating or cooling for part of the day. We work efficiently to keep downtime minimal and leave your home clean when we’re done.

Regular maintenance keeps your system running efficiently, extends its lifespan, and helps you avoid costly breakdowns at the worst possible times — like the hottest day of summer or the coldest night of winter. A well-maintained system also uses less energy, which means lower utility bills. Our technicians often catch small issues before they become expensive repairs.

Our M&S Maintenance Plan is a full-year coverage plan that includes two seasonal visits: a 30-point AC inspection and tune-up in the spring, and a 29-point heating inspection and tune-up in the fall. Members also receive priority scheduling, one air filter per service year, and a 10% discount on service and repairs. It’s the most cost-effective way to keep your system healthy year-round.

We recommend having your air conditioning system serviced once a year — ideally in the spring before summer heat arrives — and your heating system serviced once a year in the fall before cold weather sets in. Our Maintenance Plan takes care of both visits automatically.

Our 30-point AC inspection and tune-up includes condenser cleaning, drain pan and drain line inspection, refrigerant charge verification, blower motor adjustments, electrical connection tightening, capacitor testing, thermostat calibration, and much more. The goal is to make sure your system is ready to handle peak summer demands.

Our 29-point heating inspection and tune-up covers blower adjustments, safety control testing, gas pressure inspection, heat exchanger crack detection, flue draft monitoring, ignition system checks, and more. This inspection is especially important for gas furnaces, where a cracked heat exchanger can be a safety concern.

Yes! M&S Maintenance Plan members receive priority scheduling at no extra charge during regular business hours. If your system breaks down and you’re a plan member, you move to the front of the line.

Most standard 1-inch filters should be replaced every 1–3 months. Thicker media filters (4–5 inch) can last 6–12 months. How often you need to change it depends on factors like pets, allergies, or dusty conditions. A dirty filter restricts airflow, forces your system to work harder, and shortens its life. When in doubt, check it monthly.

Homeowners can handle some basics — changing the air filter, keeping the outdoor unit clear of debris, and making sure vents aren’t blocked. However, the deeper inspection work (checking refrigerant levels, testing electrical components, inspecting the heat exchanger) requires professional tools and training. We recommend professional tune-ups twice a year.

If we find an issue during your tune-up, we’ll show you exactly what we found, explain your options clearly, and provide pricing upfront before any additional work is done. Maintenance plan members receive a 10% discount on any recommended repairs.

You can sign up by visiting ms-ac.com or calling us at (775) 843-7930. Our team will get you set up and schedule your first seasonal visit.

Indoor air quality refers to the condition of the air inside your home, including pollutants like dust, pollen, mold spores, pet dander, bacteria, viruses, and VOCs (volatile organic compounds). The EPA estimates that indoor air can be 2–5 times more polluted than outdoor air. Good IAQ is especially important for people with allergies, asthma, or respiratory conditions.

There are several ways to improve indoor air quality: use a higher-quality air filter and change it regularly, consider an air purifier or UV germicidal light system installed in your HVAC, schedule regular duct cleaning, maintain proper ventilation, and keep indoor humidity levels balanced. Our team can evaluate your home and recommend the right IAQ solutions.

Yes, we offer indoor air quality services and can discuss air purification and UV light options for your HVAC system. Please contact us at (775) 843-7930 to learn more about the specific IAQ products we install.

Common signs include persistent allergy or asthma symptoms that worsen indoors, visible dust accumulating quickly, musty or stale odors, unexplained headaches or fatigue, or humidity problems like condensation on windows. If you’re concerned about your home’s air quality, we can help assess the situation.

A whole-home humidifier is installed on your HVAC system and adds moisture to dry indoor air during winter, preventing dry skin, static electricity, and damage to wood furniture and floors. A dehumidifier removes excess moisture during humid months to improve comfort and reduce mold growth. Both work automatically alongside your HVAC system. Please contact us at (775) 843-7930 for availability and pricing.

Over time, dust, pet dander, mold spores, and other contaminants accumulate in ductwork and circulate through your home every time the HVAC system runs. Professional duct cleaning removes this buildup, improving airflow and reducing airborne particles. It’s especially beneficial after renovations, if you have pets, or if you’ve moved into a home with unknown duct history.

Musty odors are usually caused by mold or mildew growth somewhere in the system — commonly in the drain pan, on the evaporator coil, or inside the ductwork. This often happens when moisture isn’t draining properly or if a refrigerant issue is causing the coil to freeze and thaw repeatedly. A maintenance visit can identify and resolve the source.

The most impactful steps are: keep up with regular maintenance (a clean, tuned system runs much more efficiently), change your air filter regularly, seal leaky ducts, add a smart thermostat to better manage your schedule, and consider upgrading to a high-efficiency system if yours is aging. Even keeping your outdoor unit shaded and clear of debris helps.

ENERGY STAR is a U.S. EPA program that certifies products meeting strict energy efficiency standards. ENERGY STAR certified HVAC equipment typically uses 15% or more less energy than standard models, which translates to real savings on utility bills over time. When recommending a new system, we can point you toward ENERGY STAR-rated options.

Yes, there can be! NV Energy and federal programs (including energy efficiency tax credits under the Inflation Reduction Act) may offer rebates or credits for qualifying high-efficiency equipment. We can help you identify potential savings when you’re considering a new system. Call us at (775) 843-7930 for the most current rebate information.

SEER2 is the updated efficiency measurement standard that replaced the original SEER rating in 2023. SEER2 tests are conducted under slightly more real-world conditions and typically produce slightly lower numbers than original SEER ratings, even for the same equipment. When shopping for a new system, make sure you’re comparing on the same scale. We’re happy to explain the difference.

The Department of Energy recommends 78°F when you’re home and cooling, and higher when you’re away or asleep. For heating, 68°F while awake and lower when sleeping or away is a good starting point. Every degree of setback can save approximately 1–3% on your energy bill — and a smart thermostat can automate this for you.

Replacing an aging system (10+ years, low efficiency rating) with a new high-efficiency unit can reduce cooling costs by 20–40% or more, depending on how inefficient the old system was. We can give you a realistic estimate based on your specific situation when you call for a consultation at (775) 843-7930.

The Reno-Sparks area has cold winters and dry air, making both high-efficiency gas furnaces (90%+ AFUE) and modern heat pumps strong choices. Cold-climate heat pumps have improved significantly and can operate efficiently even in freezing temperatures. A dual-fuel system — heat pump plus gas backup — often offers the best efficiency across our full range of seasonal temperatures.

NV Energy has historically offered rebate programs for high-efficiency HVAC equipment and smart thermostats, though programs and amounts change over time. We recommend checking NV Energy’s current offers when planning a system upgrade. Call us at (775) 843-7930 and we’ll help you navigate what’s available at the time of your purchase.

We do our best to respond quickly to urgent HVAC situations. Same-day service is available during our regular business hours (Monday–Friday 8:00 AM–5:00 PM, Saturday 8:00 AM–4:00 PM). For urgent issues, please call us at (775) 843-7930 and we’ll get to you as soon as possible.

True HVAC emergencies include complete heating failure during extremely cold weather, suspected gas leaks, carbon monoxide detector alerts related to your heating system, or flooding caused by a clogged AC condensate drain. If you suspect a gas leak or CO issue, evacuate your home immediately and call your gas company and 911 before calling us.

First, check your thermostat settings and make sure it’s set to “cool” at a temperature lower than the room. Check your circuit breaker for a tripped breaker. Replace your air filter if it’s clogged. If those steps don’t resolve it, call us at (775) 843-7930 right away and we’ll schedule you as quickly as possible.

If you smell gas, do NOT flip any light switches or touch electrical devices. Leave your home immediately, leaving the door open behind you. Once safely outside, call Southwest Gas at 1-877-860-6020 and 911. Do not re-enter until emergency responders clear the building. Then call us at (775) 843-7930 so we can inspect your system before it’s restarted.

Yes, we are available on Saturdays from 8:00 AM to 4:00 PM. For situations that arise outside of normal business hours, please call (775) 843-7930 and we’ll do our best to assist you. We understand that HVAC problems don’t always happen at convenient times.

A smart thermostat connects to your home’s Wi-Fi and can be controlled remotely from your smartphone or tablet. Many models also learn your schedule and preferences over time, automatically adjusting temperatures for comfort and efficiency. They typically show real-time energy usage and can integrate with smart home systems like Google Home or Amazon Alexa.

Yes, we install wireless and Wi-Fi thermostats as part of our services. Whether you’re upgrading from an older programmable thermostat or getting one installed alongside a new HVAC system, we’ll ensure it’s compatible with your equipment and properly configured.

Smart thermostats offer remote control from your phone, automated scheduling that adjusts temperatures based on your routine, energy usage reports that help identify savings, and potential compatibility with utility rebate programs. Some models can even detect when your home is empty and adjust automatically.

Most modern HVAC systems are compatible with today’s smart thermostats, but compatibility depends on your specific equipment and wiring. Some older systems — or systems without a C wire (common wire) — may require a simple adapter or be limited to certain thermostat models. We’ll check your system before recommending a thermostat.

We can install a variety of smart thermostat brands and will recommend one based on your HVAC system’s compatibility and your preferences. Please contact us at (775) 843-7930 to discuss what’s best for your home.

Yes — that’s one of the main benefits of a Wi-Fi thermostat. Once installed and connected to your home network, you can adjust your home’s temperature from anywhere using a smartphone app. This is great for adjusting the temperature before you head home, managing your system while on vacation, or receiving alerts if something seems wrong.

Signs that your ducts may need attention include rooms that never reach the right temperature, higher-than-expected energy bills, excessive dust near vents, hissing or rattling sounds from the duct system, or drafts you can feel near duct joints in unconditioned spaces like the attic. A professional duct inspection can identify leaks, disconnected sections, or other issues.

Leaky ducts often cause uneven comfort — some rooms are perfectly comfortable while others never seem right. You may also notice your system runs longer than it should, energy bills are higher than expected, or there’s excessive dust throughout your home. In some cases you can feel a slight draft near duct joints in the attic or crawlspace.

Duct sealing involves identifying and sealing gaps, cracks, and leaks in your duct system. The Department of Energy estimates the average home loses 20–30% of conditioned air to duct leaks — meaning you’re paying to condition air that never reaches the living spaces. Sealing ducts meaningfully improves both comfort and energy efficiency.

Duct cleaning removes dust, debris, pet dander, mold, and other contaminants from inside your ductwork. We recommend considering it if you’ve never had it done after several years in your home, if you have pets or significant allergy issues, after any major renovation, or if you notice visible mold, excess dust from vents, or signs of pest activity in the ducts.

Absolutely. Leaky or poorly insulated ducts force your HVAC system to work harder to maintain your set temperature, which increases energy consumption and puts extra wear on the equipment. Properly sealed and insulated ducts are one of the most cost-effective improvements you can make to an existing system.

Well-installed ductwork can last 20–25 years or more, but flex duct connections and seals can deteriorate sooner. Rodent damage, moisture, and improper installation can shorten the lifespan significantly. If your home’s ductwork is original to a house that’s 20+ years old or shows visible damage, it’s worth having it inspected.

A few key factors guide this decision: the age of your system (if it’s over 10–12 years old for AC or 15+ years for a furnace, replacement often makes more sense); the cost of the repair vs. a new system; the efficiency of the current equipment; and the frequency of recent breakdowns. We’ll always give you an honest assessment and let you decide.

Not necessarily. A 10-year-old, well-maintained system that’s running fine might have several good years left. But if it’s requiring frequent repairs, struggling to maintain comfortable temperatures, or using noticeably more energy than before, it may be approaching the end of its efficient life. We’ll help you weigh the options honestly.

The 5,000 rule is a simple guideline: multiply the age of your system (in years) by the estimated repair cost. If the result exceeds $5,000, replacement is generally worth serious consideration. For example, a 12-year-old system with a $450 repair comes to $5,400 — a signal to at least get a replacement quote before committing to the repair.

Warning signs include blowing warm air when set to cool, ice forming on the coil or refrigerant lines, unusual sounds like grinding or squealing, the system running constantly without reaching the set temperature, frequent refrigerant leaks, or a sharp increase in your cooling costs. Any of these warrants a call to (775) 843-7930.

Signs your furnace may be nearing end of life include increasing difficulty maintaining comfortable temperatures, frequent ignition problems or burner shutdowns, a yellow or orange burner flame (it should be mostly blue), a confirmed cracked heat exchanger, rising gas bills despite normal usage, or a furnace that’s over 15–20 years old and has been needing regular repairs.

Yes, sometimes it absolutely is. If the repair is minor — a capacitor, a contactor, a thermocouple — and the system is otherwise in good shape, a repair can buy several more reliable years at a fraction of replacement cost. We’ll always be straight with you about what we find and what we’d recommend.

Yes! We serve both residential and commercial clients throughout the Reno-Sparks region. Whether you have a small office, a retail space, a restaurant, or a larger commercial facility, our team can handle your heating and cooling needs.
