FAQ

  • Thermostats

    • Can a thermostat turn on without batteries?

      Often, a thermostat will still show something on the screen even though the battery is too low for it to perform correctly.

    • Are Wi-Fi thermostats the same as smart thermostats?

      A Wi-Fi thermostat allows remote access via internet devices, like an app on your phone or computer, while a smart thermostat might have features for automated adjustments. The two frequently overlap, and the terms are sometimes used interchangeably despite the technical differences.

    • Does my thermostat need recalibration?

      Thermostats can end up out of calibration, meaning it misunderstands your home’s temperature. Depending on the make and model, this can sometimes be easily corrected. In more serious cases, a professional will need to handle the repairs.

  • Air Purifiers

    • How often should I change my air filters?

      It depends on the filter and other factors, including whether you have pets in the home, smoke, leave windows open during the day, etc. Some filters will fill up within a month, while others may take three months. Because every home is different, we recommend checking your filters every month until you establish the ideal frequency for your home.

    • What are UV light filtration systems?

      UV light systems are units that are installed directly within your ductwork and emit a black light that neutralizes viruses, bacteria, etc., as they flow through your ducts. This can reduce illnesses and make your home smell fresher and feel more comfortable.

    • Do I need a dehumidifier in Arizona?

      We may live in a desert, but your home can be as humid as the tropics. Cooking and bathing can introduce significant moisture into your home. Installing a dehumidifier can help control mold/mildew growth and maintain the optimal balance for your desired comfort.

  • Air Scrubbers

    • How does an air scrubber work?

      Air scrubbers typically combine UV light with a catalytic process to render bacteria, viruses, and mold ineffective and remove them from the air stream. They often feature a pre-filter to remove other contaminants and allergens like dust, pollen, pet dander, and more.

    • Do air scrubbers eliminate odor?

      The UV light in an air scrubber can break down odor-causing particles from cooking, smoke, household garbage, and more. This will leave your home smelling cleaner and fresher.

    • Do air scrubbers use a lot of energy?

      Most air scrubbers use little energy, often less than a single lightbulb. Plus, they can help keep your HVAC system running more efficiently by eliminating many particles that could clog its filter or collect in the ductwork.

  • Furnace

    • How does a gas furnace work?

      With a gas furnace, combustion gasses like propane or natural gas are ignited and used to warm the air blown from the furnace fan before it’s blown into your ductwork, and throughout your home.

    • How long does an average furnace last?

      A well-maintained furnace can last about 15 to 20 years.

  • Heat Pump Installation

    • Can I use a heat pump to cool my home as well?

      Yes, heat pumps can both heat and cool your home, making them ideal for year-round comfort.

    • Are heat pumps better heaters than furnaces?

      Each system has its benefits, but heat pumps are much more efficient than furnaces. Although furnaces produce hotter air than heat pumps, making them preferable in many northern areas, heat pumps are great options for Phoenix’s climate, where winter temperatures are typically mild.

    • Do heat pumps work when it’s cold outside?

      Yes, heat pumps even work when it’s cold outside, but the colder it is, the harder they work to do so. That means that as it gets colder, it becomes less energy-efficient. However, they’re ideal for Phoenix’s climate, where temperatures are rarely below freezing.

  • Heat Pumps

    • How long do heat pumps last?

      You can expect a heat pump to last about 15 to 20 years with normal usage and routine maintenance.

    • Should my heat pump be repaired or replaced?

      Usually, a professional repair is sufficient to get a heat pump running properly again. However, if your system needs frequent repairs or is over 15 years old, your money is better invested in a new system. Our team can help you determine which option is best for your system and home.

    • Are heat pumps loud when operating?

      Heat pumps are quieter than many other heating and cooling systems, making them an ideal choice if you’re looking for a quiet system.

  • Ductless Mini-Split Maintenance

    • When should I schedule ductless mini-split maintenance?

      We recommend annual maintenance just before peak operating season. If you’re using your ductless mini-split for cooling, schedule a tune-up in the spring. Schedule maintenance mid-fall if you use your system for heating.

      • How long should my ductless mini-split system last?

        If your system gets regular quality maintenance, it could last as long as 15 to 20 years, though multiple factors, such as usage frequency, will affect your specific system’s lifespan.

        • What are the primary parts of a ductless mini-split?

          Specifics will vary depending on the model and type of mini-split, but in general, the major components include:

          • An indoor air handler that moves the air in the affected zone
          • An outdoor condenser (the cooling component)
          • An outdoor heat pump that uses both a condenser and evaporator on systems that include heating
          • Conduits that connect wiring and refrigerant between the indoor and outdoor units
      • Ductless Mini-Split Repair

        • How long does a ductless mini-split system last?

          If regularly maintained, a ductless mini-split can last 15 to 20 years. It’s one of the most durable HVAC systems, making it a popular and energy-efficient choice.

        • How can I best maintain my ductless mini-split?

          Enjoy zoned temperature control for longer with simple at-home steps. We recommend you replace your air filters every other month and keep coils free of dust. Regularly check outdoor units and keep the area around them clear of dirt buildup or debris. Scheduling annual maintenance will ensure minor problems with your system don’t become a major expense.

        • Will a ductless mini-split heat and cool my entire home?

          If properly installed, a ductless mini-split system is a whole-home solution. A single indoor and outdoor unit will exchange or remove heat, allowing you to control and modify the temperature in every room individually.

      • Ductless Mini-Split Installation

        • How often should a ductless mini-split system be serviced?

          We recommend a twice-a-year maintenance schedule to ensure your system runs efficiently. These tune-ups can extend the life span of your system and allow our technicians to catch and fix minor problems before they become major issues.

        • Is a ductless mini-split system more efficient than a traditional HVAC system?

          Yes. Due to their lack of ductwork, mini-split systems generally offer better energy efficiency than traditional HVAC systems.

        • How long does it take to install a ductless mini-split system in Phoenix?

          Installation time can vary depending on several factors, but typically, our expert team at Donley A/C & Plumbing can install a system within one day.

        • Can I replace a well pump myself?

          No. Professional plumbers should be performing well pump replacements to ensure the process is done correctly.

        • What is the lifespan of a well pump?

          The average lifespan of a well pump is between 15 and 25 years. You’ll notice changes in water pressure, increased utility bills, and the need for more well pump repairs as your system ages.

      • Trenchless Sewer Services

        • How does trenchless sewer lining work?

          Through a combination of remote interior video inspection, removal of obstructions, and materials installed through one end of the sewer pipe, the sewer line is repaired without the need for a trench.

        • Is trenchless sewer line service safe?

          Yes. There’s little to no digging, no interference with your home’s foundation, and no exposure to hazardous materials.

        • Why would trenchless piping last longer than metal?

          Trenchless piping uses materials, usually epoxy, that don’t rust. It’s water-resistant and tougher against residue buildup.

        • How long will it take to repair my sewer line?

          Sewer line repairs could take a single visit or multiple visits, depending on the severity of the damage. Our team will discuss your situation and work around your schedule.

        • Will you need to dig up my yard to perform the repair?

          We’ll perform trenchless sewer line repairs if possible. Depending on the situation, our team may need to dig up the sewer line to complete the repair.

        • How often do I need to repair my line?

          If maintained properly, your sewer line may not need repairs for decades. Avoid flushing thick materials and pouring oil down your drains, as these items can cause blockages and other issues.

      • Sewer Ejector Pumps

        • How do I know if my sewage ejector pump is failing?

          It will be easy to know when a sewage ejector pump has issues. You may notice bubbling drains, clogged toilets, or an unsanitary smell. These are all signs that it’s time to call for assistance.

          The process of replacing a sewage ejector pump takes a short time. Our team can handle the job in just an hour or two on a single visit to your home.

      • Sewer Camera Inspection

        • What problems can a sewer camera inspection detect?

          Our sewer cameras can detect cracks and breaks in your pipes, pipe misalignment, tree root infiltration, debris and sludge buildup, blockages, leaks, sagging, bellying, and other common issues.

        • Can I rent a sewer camera?

          It’s possible to rent or buy sewer cameras to inspect your pipes. However, we don’t recommend it. While there is minimal risk of damaging your pipes, inspections require specialized skills and training to accurately identify issues within the pipes. DIY inspections often miss critical signs that our highly trained plumbers will easily detect.

        • When should I perform a sewer camera inspection?

          We recommend inspections any time you are buying or selling a home, when issues are detected, and prior to the performance of any major plumbing renovations to your home.

      • Water Softener

        • How long does a water softener last?

          A good water softener will last for many years with regular maintenance and occasional salt refills.

        • How do I know if my water is hard?

          We can test your water to determine how hard it is and the level of minerals in it. This will help you determine if a water softener is right for you.

        • Does soft water taste bad?

          Many people prefer the taste of hard water. That’s why we often provide an un-softened tap in the kitchen for cooking and drinking.

      • Water Filtration

        • What signs indicate I need a water filtration system?

          There are several signs homeowners can look for that mean it may be time for a water filtration system. Common signs include a strange odor or taste in your water, visible sediment, or frequent plumbing issues caused by mineral deposits. These signs suggest that your water quality may be compromised, and a filtration system can help remove impurities and improve taste.

        • Can I install a water filtration system myself?

          While DIY options are available, we highly recommend having a professional install your water filtration system. Professional installation ensures the system is correctly set up, properly connected to your plumbing, and meets the standards for optimal performance and longevity.

        • How often should I replace the filters in my water filtration system?

          The frequency of filter replacement depends on different factors, including the type of system and your water quality. As a general guideline, most filters need to be replaced every six to 12 months.

      • Sump Pumps

        • How can I tell if I’ll need a sump pump?

          Any building with a portion of its structure underground will likely need a sump pump. Water can enter through foundation cracks and joints, especially when near a high water table and after storms.

        • How does the sump pump know there’s water to remove?

          As water enters the sump pump housing or pit, a float rises with the water level. This float is attached to a switch that activates the pump. The water level recedes as the water is removed, and the switch deactivates the pump.

        • How long should my sump pump last?

          Most sump pump models have a life expectancy of around 10 years. Water quality and maintenance visits can affect how long the unit lasts.

      • Leak Detection

        • Is it safe to use drain cleaner when I have a clog?

          While drain cleaners can quickly fix slow drains, they often contain harsh chemicals that can damage your pipes over time. A mixture of vinegar and baking soda or a plumber’s snake can be a safer alternative for minor clogs. For persistent issues, it’s best to consult a plumber.

        • How can I prevent future plumbing leaks?
          • Check all your pipes, appliances, and plumbing fixtures regularly.
          • Make sure your water pressure is good.
          • If you have hard water, think about getting a water softener.
          • Replace old or corroded pipes.

          • Use appliances per their instructions.
          • Have a professional plumber check your plumbing yearly.
        • How can I tell if I have a hidden water leak?

          To find hidden water leaks in your home:

          • Keep an eye on your water bill for any unexpected increases.
          • Check your water meter to see if it’s moving when no water is used.
          • Look for signs of moisture or damage, like mold, mildew, or discoloration on walls and ceilings.
          • Listen for dripping sounds and do a food coloring test in the toilet tank to find hidden leaks.

          If you can’t find the leak, it’s best to call a professional plumber to inspect your home thoroughly.

      • Gas Lines

        • How do I shut off my gas supply?

          In most homes, there’s a street-side valve located just before the line reaches the outside gas meter. There should also be a valve inside your home where the pipes enter, usually in a utility area or basement.

        • Why do I need to install a gas line?

          If you don’t have one, you’ll need a gas line to power gas-powered appliances such as stoves or water heaters or if you purchase a gas furnace.

        • How long should my gas line last?

          Corrugated steel gas lines may last around 30 years. Black steel piping may last over 75 years. PVC lines don’t have an estimated life span yet. Preventative maintenance can extend your line’s life span even more.

      • Sinks

        • How long does a typical sink repair or installation take?

          The time frame for sink repair or installation can vary based on the job’s requirements. Typically, repairs can be completed within a few hours, while installations may take longer, depending on the complexity.

        • Can a leaking sink lead to other problems?

          A leaking sink can lead to other plumbing problems if not addressed promptly. Continuous leaks can cause water damage to cabinets and floors, promote mold and mildew growth, and may even affect the structural integrity of your home over time.

        • How often should I inspect my sink and its components for potential issues?

          Regular inspection of your sink and its components is crucial for the early detection of potential issues. It’s best to inspect your sink at least every six months. Look for signs of wear and tear, such as rust or mineral deposits, check for smooth operation of the faucet, and ensure no slow leaks or drips.

      • Faucets

        • Can I replace my faucet on my own?

          Only a professional should perform faucet replacements. If you attempt the replacement alone, you risk choosing the incorrect size, damaging your vanity, and more.

        • What causes fixtures to leak?

          There are a few reasons plumbing fixtures leak, including broken seals, corrosion, clogged lines, incorrect pipe laying, tree root infiltration, and high water pressure.

        • What causes a dripping faucet?

          Typically, your faucet will drip due to a broken cartridge. The cartridge is found in the handles and is used to stop and start water flowing. When it’s broken, water will drip regardless of whether the faucet is on or off.

      • Electric Water Heater

        • How long does an electric water heater last?

          With proper maintenance, electric water heaters can last 10 to 15 years.

        • How do I know if my gas water heater needs repair or replacement?
          If your water heater is leaking, producing rusty water, making unusual noises, or struggling to provide hot water consistently, it may need repairs. If it’s over 10-12 years old, replacement might be the best option for efficiency and reliability.
        • How often should I flush my gas water heater?
          To prevent sediment buildup and maintain efficiency, it's recommended to flush your gas water heater at least once a year. If you have hard water, more frequent flushing may be necessary.
        • What should I do if my gas water heater isn’t producing hot water?
          First, check the pilot light—it may need to be relit. If the pilot is on, but you still don’t have hot water, there could be an issue with the thermostat, gas supply, or sediment buildup. If troubleshooting doesn’t resolve the issue, call a professional for an inspection.
      • Garbage Disposal

        • How long will my garbage disposal last?

          With proper maintenance and use, your garbage disposal can last 10 to 12 years. Certain waste products can impact the system’s lifespan, so stick to approved food items and promptly schedule repairs when necessary.

        • How can I maintain my garbage disposal system?

          Avoid damaging food products, and allow your garbage disposal to run for a few seconds after turning it on. Cold water rinses also help prevent clogging, while grinding up citrus fruit peels freshens and improves odor.

        • Can I fix a clogged garbage disposal on my own?

          Removing a food item on your own is possible if the blockage is visible, but safety is key. Never place a hand inside a garbage disposal drain; only insert pliers or tongs once the unit is fully turned off and cooled.

      • Kitchen Plumbing

        • What should I do if a pipe bursts?

          First, shut off the water. From there, clean any standing water and air out the area with fans, if necessary, to prevent water damage. Then, call our team as soon as possible to schedule a plumbing repair.

        • How long do garbage disposals last?

          Typically, a garbage disposal will last 10 years with regular maintenance and care.

        • Why is my kitchen faucet leaking?

          The most common reason kitchen faucets leak is an O-ring that’s failed, but a variety of other causes could be the culprit. Our team can inspect your sink and drain to determine the best solution.

      • Hydro-Jetting

        • How is hydro jetting different than drain cleaning?

          Drain cleaning involves scraping your drainage system with tools like plumbing snakes. Hydro jetting clears stubborn clogs by applying highly pressurized water.

        • How long does a hydro jetting session last?

          Depending on the severity of a drain or sewer clog, the hydro jetting process can take 10 minutes to a few hours.

        • Can hydro jetting cause plumbing damage?

          No, hydro jetting is not damaging when performed by a professional. An amateur hydro jetting session can unintentionally damage plumbing, especially if your pipes have preexisting issues.

      • AC Installation

        • How long does an AC replacement typically take?
          The duration can vary depending on the installation’s complexity and the system’s size. However, technicians usually finish a basic installation in one to two days.
        • Do I need to replace my ductwork when I replace my AC system?

          It depends on the condition of your existing ductwork. If your ductwork is in good condition and adequately sized for the new system, you may not need to replace it. However, if your ductwork is damaged, leaking, or improperly sized, it may need to be replaced to ensure the new system functions properly and efficiently.

          An experienced HVAC technician can assess the condition of your ductwork and provide recommendations for replacement if necessary.

      • Drain Cleaning

        • What’s the difference between a drain and a sewer line?

          Your sewer line refers to the main pipe into which all of your drains feed, the pipe that carries waste water away from your home to the municipal sewer system or your septic tank. A problem affecting a drain may only affect one drain or only affect drains that are “upstream” of the clog, while a sewer line issue will affect every drain in your home.

        • Is drain cleaning safe for my pipes?

          When performed by a knowledgeable professional, drain cleaning is generally safe for your drains and sewer. The only exception would be with pipes that are already substantially damaged, something that should be detected quickly and would need to be resolved with repairs or replacement.

        • Should I have drain cleaning regularly as maintenance?

          Drain cleaning before problems develop can be a great way to avoid the headache of noticing toilets and sinks start to clog more frequently, dealing with bad smells, or risking backflow or overflow of toilets, laundry drains, etc. Depending on the state of your pipes, the quality of your water, and other factors, you may need drain cleaning only every few years or might need it multiple times annually.
