Do you install ductless mini-split systems?

Please contact us at (469) 275-6263 to discuss whether a ductless mini-split is a good fit for your home or addition.

What size AC unit do I need for my home?

The right size depends on your home's square footage, insulation, window placement, ceiling height, and more — bigger isn't always better, since an oversized unit can actually perform worse. Our technicians can evaluate your home and recommend the correctly sized system. Call us at (469) 275-6263 to schedule an assessment.

Do you install heat pumps?

Please contact us at (469) 275-6263 to discuss heat pump installation options for your home.

Can you replace just my outdoor unit, or does it need to match the indoor unit?

In most cases, your indoor and outdoor units need to be matched for proper efficiency and performance, and mismatched systems can cause issues down the road. We can inspect your current setup and let you know what makes sense — call us at (469) 275-6263.

How do I know if I need a new system vs a repair?

It depends on your system's age, repair history, and the cost of the current issue compared to a replacement. As a general rule, if your system is older and facing a costly repair, replacement often makes more financial sense long-term. Our technicians will give you an honest recommendation — not just an upsell — when they inspect your system.

Installation Process

What does a full HVAC installation involve?

A full installation typically includes removing your old equipment, installing the new indoor and outdoor units, connecting refrigerant lines and ductwork, testing the system, and walking you through how to operate it. We also take before-and-after photos so you have a clear record of the work.

How long before a new system starts working after installation?

Your new system is tested and fully operational before we leave, so you'll have working heating or cooling the same day your installation is complete.

Do you handle permits for installations?

Please contact us at (469) 275-6263 to discuss permit requirements for your specific installation project.

Will you remove and dispose of my old unit?

Please contact us at (469) 275-6263 to confirm removal and disposal details for your installation.

Do I need to be home during installation?

We recommend being home or available at the start and end of the installation so we can walk through the details of your new system together, though specific requirements can vary by job. Call us at (469) 275-6263 if you have questions about your particular installation.

What should I do to prepare for an installation appointment?

Clearing access to your indoor equipment (like a closet or attic unit) and outdoor condenser helps our technicians work efficiently. If you have any pets, it's helpful to keep them in a separate area during the visit. Give us a call at (469) 275-6263 if you have specific questions before your appointment.

Do you test the system after installation?

Yes, we thoroughly test every system after installation to confirm it's running properly, and we document the work with before-and-after photos so you have a clear record of what was done.

Maintenance & Tune-Ups

How often should I have my HVAC system serviced?

We recommend having your system professionally serviced at least once a year — ideally once before the cooling season and once before the heating season — to catch small issues before they become expensive repairs.

What's included in a maintenance visit?

A maintenance visit typically includes inspecting and cleaning key components, checking refrigerant levels, testing electrical connections, and evaluating overall system performance. We also log the results so you have a record of your equipment's health over time.

Do you offer a maintenance plan?

Please contact us at (469) 275-6263 to ask about current maintenance plan options.

Why is regular maintenance important?

Regular maintenance helps your system run efficiently, extends its lifespan, and catches small problems before they turn into costly breakdowns — especially important here in Texas, where our systems work hard through long, hot summers.

What happens if I skip annual maintenance?

Skipping maintenance can lead to reduced efficiency, higher energy bills, and a greater chance of unexpected breakdowns — often at the most inconvenient time, like the middle of a Texas summer. It can also shorten your equipment's overall lifespan.

Can I do any maintenance myself between visits?

Yes — regularly changing or cleaning your air filter is the biggest thing homeowners can do between professional visits. Keeping the area around your outdoor unit clear of debris and vegetation also helps. Beyond that, we recommend leaving technical maintenance to a licensed professional.

Do you keep records of my system's history?

Yes, we create digital records to track your equipment's health over time, which helps us spot trends, plan ahead for repairs, and give you a clearer picture of your system's condition at every visit.

Will maintenance void my system's warranty if I don't use Two7 Mechanical every time?

Manufacturer warranty requirements vary by brand, but most require documented, regular maintenance by a licensed professional — it doesn't necessarily have to be the same company every time. Please contact us at (469) 275-6263 if you have specific questions about your equipment's warranty terms.

Indoor Air Quality

Can you help with indoor air quality issues?

Yes, indoor air quality is part of what we help homeowners with. Please contact us at (469) 275-6263 to talk through the specific concerns you're having.

Do you install air purifiers?

Please contact us at (469) 275-6263 to discuss air purification options for your home.

How often should I change my air filter?

As a general guideline, most standard filters should be changed every 1–3 months, though homes with pets, allergies, or higher dust levels may need more frequent changes. We're happy to recommend a schedule based on your specific filter type and household.

Can poor duct sealing affect my indoor air quality?

Yes, leaky or poorly sealed ducts can pull in dust, allergens, and unconditioned air from attics or crawl spaces, which affects both your air quality and your system's efficiency. If you suspect duct issues, give us a call at (469) 275-6263.

Do you offer humidity control solutions?

Please contact us at (469) 275-6263 to discuss humidity control options for your home.

What causes musty smells from my vents?

Musty odors are often a sign of moisture buildup, mold or mildew growth in the ductwork, or a clogged condensate drain line. It's worth having a technician take a look before the issue affects your air quality — call us at (469) 275-6263.

Energy Efficiency & Rebates

How can I lower my energy bills with a new HVAC system?

Newer, higher-efficiency systems use less energy to heat and cool your home, which can meaningfully lower your monthly bills — especially if your current system is older or undersized. Regular maintenance, a properly sealed duct system, and a smart thermostat can also help you save.

What is a SEER rating?

SEER stands for Seasonal Energy Efficiency Ratio, and it measures how efficiently an air conditioner cools your home over a typical season. The higher the SEER rating, the more efficient the unit — meaning lower energy costs to run it.

Are there rebates available for upgrading my system?

Rebates and incentives change frequently and depend on your utility provider and the equipment you choose. Please contact us at (469) 275-6263 and we can help point you toward current options.

Is a higher SEER rating always worth the extra cost?

Not always — it depends on your climate, how much you run your system, and how long you plan to stay in your home. In Texas, where systems run heavily for much of the year, a higher SEER rating often pays for itself faster than in milder climates. We can help you weigh the upfront cost against long-term savings.

Do newer systems really use less energy?

Yes, HVAC technology has improved significantly over the past decade, and newer systems are generally far more efficient than units that are 10–15+ years old, even before accounting for wear and tear on aging equipment.

Can you help me find available rebates or tax credits?

Please contact us at (469) 275-6263 and we'll do our best to point you toward any rebates or incentives that may apply to your project.

Emergency Service

Do you offer emergency HVAC service?

Please contact us at (469) 275-6263 to ask about emergency service availability — we understand how urgent a heating or cooling failure can feel, especially in extreme weather.

What counts as an HVAC emergency?

Situations like a complete system failure during extreme heat or cold, a gas smell near your furnace, strange burning odors, or visible water leaking from your system are all considered emergencies. If you're ever unsure, it's always safest to call us at (469) 275-6263.

Is emergency service available on weekends?

Please contact us at (469) 275-6263 to check current weekend availability.

What should I do if my AC stops working during a heat wave?

First, check your thermostat settings and breaker panel to rule out simple issues. If the system still isn't working, call us at (469) 275-6263 right away — we understand how important it is to get your home cooling again quickly during extreme heat.

What should I do if I smell gas near my furnace?

If you smell gas, leave the area immediately, avoid using light switches or open flames, and contact your gas utility provider or emergency services first. Once it's safe, give us a call at (469) 275-6263 so we can inspect your system.

Is there an extra charge for emergency calls?

Please contact us at (469) 275-6263 for details on emergency service pricing.

Smart Thermostats

Do you install smart thermostats?

Please contact us at (469) 275-6263 to discuss smart thermostat installation for your home.

What brands of smart thermostats do you recommend?

The right smart thermostat depends on your system and personal preferences. Give us a call at (469) 275-6263 and we can recommend an option that pairs well with your equipment.

Can a smart thermostat really save me money?

Yes, smart thermostats can lower energy costs by automatically adjusting temperatures based on your schedule and habits, avoiding energy waste from heating or cooling an empty house.

Will you help me set up my smart thermostat after installation?

Please contact us at (469) 275-6263 to confirm setup and walkthrough support for your smart thermostat.

Can I control my HVAC system remotely with a smart thermostat?

Yes, most smart thermostats connect to an app on your phone, letting you adjust the temperature, check system status, and sometimes get maintenance reminders from anywhere.

Duct Work

Do you repair or replace ductwork?

Please contact us at (469) 275-6263 to discuss ductwork repair or replacement for your home.

How do I know if my ducts are leaking?

Signs of leaky ductwork include uneven temperatures between rooms, higher-than-expected energy bills, dust buildup near vents, and visible gaps or disconnected sections in accessible ducts. A technician can perform a more thorough inspection if you suspect a leak.

Can bad ductwork cause uneven heating and cooling?

Yes, leaky, poorly sized, or disconnected ductwork is one of the most common causes of rooms that feel too hot or too cold compared to the rest of the house, even when your HVAC system itself is working fine.

Do you clean air ducts?

Please contact us at (469) 275-6263 to ask about duct cleaning services.

How often should ductwork be inspected?

We recommend having your ductwork checked as part of your annual maintenance visit, or sooner if you notice signs like uneven temperatures, rising energy bills, or dust buildup around vents.

Can new ductwork improve my system's efficiency?

Yes, properly sized and sealed ductwork helps your system deliver conditioned air where it's supposed to go instead of losing it to leaks, which can noticeably improve comfort and lower energy costs.

Repairs & Troubleshooting

My AC is running but not cooling — what's wrong?

This can point to several issues, including low refrigerant, a dirty air filter, a failing compressor, or frozen evaporator coils. It's best to have a technician diagnose the exact cause rather than guessing — call us at (469) 275-6263.

Why is my furnace making strange noises?

Banging, rattling, or squealing noises can indicate anything from a loose panel to a failing blower motor or ignition issue. It's worth having it looked at before a minor issue turns into a bigger repair — give us a call at (469) 275-6263.

Why does my AC keep freezing up?

Frozen coils are often caused by restricted airflow (like a dirty filter), low refrigerant, or a mechanical issue with the blower. Turning the system off and letting it thaw can help temporarily, but a technician should diagnose the root cause. Call us at (469) 275-6263.

What does it mean if my system is low on refrigerant?

Low refrigerant almost always means there's a leak somewhere in the system, since refrigerant doesn't get "used up" under normal operation. We can locate and repair the leak and recharge your system properly — call us at (469) 275-6263.

Why does my thermostat show one temperature but the house feels different?

This can happen due to poor thermostat placement, duct leaks, insulation issues, or a system that's struggling to keep up with demand. A technician can help pinpoint the cause during an inspection.

Why is my energy bill suddenly higher than usual?

A sudden jump can be caused by a system working harder due to a dirty filter, low refrigerant, duct leaks, or aging equipment losing efficiency. Extreme weather can also play a role, but if the increase seems unusual, it's worth having your system checked.

What should I do if my system won't turn on at all?

Start by checking your thermostat batteries and settings, and check your breaker panel for a tripped breaker. If it still won't turn on, give us a call at (469) 275-6263 and we'll get a technician out to diagnose it.

How can I tell if a repair is worth it vs replacing the unit?

Consider your system's age, how often it's needed repairs recently, and how the repair cost compares to the cost of a new system. Older systems facing expensive repairs are often better candidates for replacement. Our technicians will give you an honest recommendation either way — not a sales pitch.

Heating & Cooling Specifics

What's the difference between a furnace and a heat pump?

A furnace generates heat by burning gas or using electric resistance, while a heat pump moves existing heat from outside air into your home (and can reverse to cool your home in summer too). Heat pumps tend to be more energy-efficient in milder climates, while furnaces can provide stronger heat output in colder conditions.

How often should I replace my furnace?

Most furnaces last 15–20 years with regular maintenance, though performance and efficiency typically start declining well before that. If your furnace is approaching the end of its lifespan or needing frequent repairs, it may be time to talk about replacement options.

What's the average lifespan of an AC unit in Texas heat?

With regular maintenance, most AC units last around 12–15 years, though our long, hot Texas summers mean systems here often work harder than in milder climates, which can shorten that lifespan without consistent upkeep.

Do you service both gas and electric heating systems?

Please contact us at (469) 275-6263 to confirm we can service your specific type of heating system.

Why does my house feel humid even with the AC running?

This can happen if your system is oversized (cooling the air quickly without running long enough to remove humidity), if there's a mechanical issue, or if your ductwork isn't properly sealed. A technician can evaluate what's driving the humidity in your specific case.

Should I turn off my AC at night to save energy?

We generally recommend against turning your system off completely, especially during Texas summers, since it has to work much harder to cool the home back down. A programmable or smart thermostat that adjusts the temperature slightly overnight is usually a better way to save energy.

What temperature should I set my thermostat to in summer?

A common recommendation is around 78°F when you're home and a few degrees warmer when you're away, balancing comfort with energy savings. The right setting ultimately comes down to your personal comfort and household needs.

Does Two7 Mechanical work on commercial HVAC systems, or just residential?

Please contact us at (469) 275-6263 to confirm whether we can take on your specific commercial or residential project.
