Can I keep running my AC while it's frozen?

No, running a frozen system can put extra strain on the compressor, which is one of the most expensive parts to replace. Turn it off and let it thaw first.

How long does it take a frozen AC unit to thaw?

Usually a few hours, depending on how much ice has built up. Avoid the temptation to speed it up by chipping at the ice.

Will a portable generator run my AC unit?

Most portable generators aren’t powerful enough to run a full air conditioning system. Whether it can depends on both the size of your generator and the size of your AC unit. If you want to keep your whole home, including your HVAC, running during an outage, a whole-home generator is usually the better choice. Our licensed electricians can help you figure out the right setup for your home and make sure it’s installed safely.

Will an air purifier work with my HVAC system?

Almost always. The Air Scrubber by ActivePure installs into your existing ductwork without new equipment, so most homes can add one as-is. We confirm compatibility during our evaluation, and if a whole-home install isn't practical, the portable Pure & Clean needs no installation at all.

How much does an air purifier cost?

The total cost depends on your specific home and the system you select. We provide a clear, upfront quote before any work begins, and financing is available if you prefer to spread the cost over time. Systems generally run between $450 and $3,800 for whole-home air purifiers, UV lights, and dehumidifiers.

How much maintenance does an air purifier need?

Very little. The Air Scrubber's ActivePure cell is replaced periodically and is covered for two years, while the portable Pure & Clean is designed to be low-maintenance and easy to use. We'll walk you through the simple upkeep for whichever system you choose.

Do air purifiers really work?

ActivePure technology has been validated in extensive independent lab testing and was inducted into the Space Technology Hall of Fame in 2017. That said, we'll always be straight with you: an air purifier is one layer of a healthy home, and we'll tell you honestly whether it's the right fit for what you're dealing with.

Who benefits most from whole-home media filtration?

Homeowners with allergies or breathing issues benefit the most. If anyone in your home struggles with seasonal allergies, asthma, or general sensitivity to dust and dander, whole-home filtration removes far more of those triggers from the air than a standard filter ever could.

How will I know it's actually making a difference?

This is one of the most common questions we hear, and it's a fair one. Most homeowners notice less dust settling on surfaces, fewer allergy flare-ups indoors, and fresher-feeling air in the weeks after installation. Results depend on your home and the specific particles you're dealing with, so we'll talk honestly with you about what to expect for your situation rather than overpromising.

Does installation require modifying my ductwork?

It may. Fitting a media filter cabinet sometimes calls for modifying the existing ductwork so everything seals and fits properly. We'll assess this during our evaluation and explain exactly what your installation involves before we begin.

How long does installation take?

Most installations are completed in less than a day.

How often does the filter need to be replaced?

That depends on the type of filter, the condition of your home, and your duct system — a home with pets or heavy dust will go through filters faster than a tightly sealed, low-traffic one. Media filters generally last far longer than standard one-inch filters. Most modern thermostats can be set to remind you when a replacement is due, so you're never guessing.

How much does whole-home media filtration cost?

Most installations fall between $700 and $2,500, depending on the system you choose and what your installation involves. We'll give you a clear price before any work begins, and financing is available if you'd like to spread the cost out.

How much does electrical repair cost near Raleigh?

Electrical repair costs vary based on the problem's complexity, parts needed, and time required. Simple repairs like replacing an outlet might cost $100-200, while more involved work like rewiring circuits or panel repairs can run several hundred to a few thousand dollars. We provide upfront, flat-rate pricing before starting work, so you'll know exactly what to expect with no surprises.

Is a whole-home filter better than a portable air purifier?

For whole-house results, yes. A portable unit only treats the room it's in, while a whole-home media filter cleans the air everywhere your system delivers it — automatically, every time it runs. Many homeowners pair filtration with other indoor air quality solutions for more complete coverage.

What does a germicidal UV light actually do?

It emits UV-C light — the same type produced by the sun — which kills harmful mold, bacteria, and fungi inside your HVAC system. Its biggest job is keeping biological growth off the evaporator coil, where humid North Carolina conditions would otherwise let mold flourish.

Do UV lights kill mold throughout my entire duct system?

This is the most common misconception we hear. A UV light works where its light reaches — primarily the coil and the area immediately around the lamp. It does not sanitize every foot of ductwork in your home. If your goal is to address contamination deeper in the duct system, that's a job for duct cleaning or system sanitizing, which we're happy to discuss alongside a UV option.

Where is the UV light installed — the air handler, the ductwork, or both?

It depends on your system's design. We install UV lights in the air handler, in the ductwork, or both, and we position the lamp wherever it will be most effective. For coil sanitizing, that usually means mounting it so the light shines directly onto the coil.

Will a UV light work with my HVAC system?

In almost all cases, yes. Germicidal UV lights are compatible with nearly every type of HVAC system, so most homeowners can add one regardless of the equipment they currently have.

How long does installation take?

For most homes, installation takes less than an hour.

How often do the UV bulbs need to be replaced?

UV bulbs typically need replacement every one to two years, since their germicidal output fades over time even when the bulb still appears to be lit. Replacement is straightforward and something we can take care of for you when the time comes.

How much does a germicidal UV light cost?

Most installations fall in the range of $400 to $700, depending on the system you choose and how it's configured for your home. We'll give you a clear price before any work begins. Ask us about financing if you'd like to spread the cost out.

Are germicidal UV lights safe?

Yes. The UV-C light is fully contained inside your sealed HVAC system, so it's never exposed to the living areas of your home. It does its work out of sight while your system runs.

Who tends to ask about UV lights?

Most often, it's homeowners who've been told there's biological growth inside their HVAC system and want to stop it at the source. If that's you, a UV light is one of the most direct, cost-effective tools available.

How long do electrical repairs take?

Most electrical repairs take a few hours to complete, depending on the issue. Simple fixes like replacing switches or outlets might take 30 minutes to an hour, while troubleshooting wiring problems or panel repairs can take several hours. We'll give you an estimated timeframe when we diagnose the problem and explain what needs to be done.

Do electrical repairs require permits?

Many electrical repairs require permits, especially work involving wiring, circuits, or panel modifications. Simple replacements of existing fixtures or outlets might not need permits, but most repairs do. We handle all necessary permits and inspections, ensuring your repairs meet local codes and pass inspection without you having to navigate the permitting process yourself.

How often should I have an electrical safety inspection of my home?

It’s recommended to have a professional electrical safety inspection once a year. Annual inspections help catch potential hazards early, like loose connections inside your panel, outdated wiring, or failing safety devices. During a yearly visit, your electrician can tighten connections, test GFCI and AFCI protection, check smoke and carbon monoxide detectors, and make sure your home’s electrical system is running safely and efficiently. At Dawson’s Electric & Air, our Peace of Mind Club members receive a 32-point electrical system evaluation every year, plus other safety and maintenance benefits to help prevent unexpected breakdowns. It’s the easiest way to stay proactive about your home’s electrical health.

How much does it cost to upgrade my electrical service near Raleigh?

The cost depends on the amperage you're upgrading to and your home's specific situation. Upgrading from 100-amp to 200-amp service typically runs between $2,000 and $4,000 for most homes in the Raleigh area. If your home needs additional work like panel relocation, new wiring, or service line upgrades from the utility, costs can be higher. We provide upfront pricing so you know exactly what to expect.

How long does an electrical service upgrade take to complete?

Most electrical service upgrades take one to two days to complete from start to finish. The actual work time depends on factors like panel location, accessibility, and whether additional wiring or repairs are needed. We coordinate with your utility company to ensure minimal disruption, and we'll keep you informed every step of the way so you know what to expect.

Do I need a permit to upgrade my electrical service?

Yes, electrical service upgrades require permits in North Carolina to ensure the work meets current safety codes and building standards. The good news is we handle all the permitting and inspections for you as part of our service, so you don't have to worry about the paperwork or dealing with inspectors. Everything is done properly and legally from start to finish.

How much does whole-home surge protection cost near Raleigh?

Whole home surge protectors typically cost $200-$700, including the device and professional installation. The final price depends on your electrical panel type, the surge protector's capacity and features, and installation complexity. Higher-capacity units that handle larger surges cost more but provide better protection. We provide upfront pricing and can recommend the right level of protection for your home's needs.

How long do whole-home surge protectors last?

Most whole-home surge protectors last 3-5 years under normal conditions, though this varies based on how many surges they handle. Each surge they block depletes their protective capacity gradually. Many units have indicator lights showing when they need replacement. We recommend having yours checked during electrical inspections to ensure it's still providing adequate protection.

Will a frozen coil damage my compressor?

It can, if the system keeps running while frozen or if it happens repeatedly without the underlying cause being fixed. That's the main reason we recommend having it looked at even after it thaws on its own.

Does homeowners' insurance cover surge damage?

Most standard homeowners' insurance policies provide limited or no coverage for surge damage to electronics and appliances. Even policies that cover lightning strikes often don't cover the resulting surge damage or have low coverage limits. Installing whole-home surge protection prevents damage in the first place, which is far better than hoping your insurance will cover replacements.

How much does it cost to install or replace outlets near Raleigh?

The cost varies depending on the outlet type and whether new wiring is needed. Standard outlet replacement typically runs $75 to $150 per outlet, while GFCI and AFCI outlets cost $100 to $200 due to their safety features. USB outlets usually run $125 to $175. We always provide upfront, flat-rate pricing before starting work, so there are no surprises.

How many outlets should I have in each room?

Building codes require outlets spaced so that no wall point is more than six feet from an outlet, typically meaning outlets every 12 feet. Kitchens need outlets every four feet along countertops. Most bedrooms need four to six outlets, while living rooms might need six to ten, depending on size. If you're constantly using extension cords, you likely need more outlets.

Can I replace a two-prong outlet with a three-prong outlet myself?

You can't simply replace a two-prong outlet with a three-prong outlet unless a ground wire is present. Installing three-prong outlets without proper grounding is dangerous. Safe options include installing GFCI outlets (which don't require grounding), running new grounded wiring, or keeping two-prong outlets. An electrician can evaluate your situation and recommend the safest, code-compliant solution.

How do I test an outlet?

You can do a basic check by plugging in a small device, like a lamp, to see if the outlet is working. However, for safety and accuracy, it’s best to have a licensed electrician test your outlets using a receptacle tester. A professional can make sure the outlet is properly wired, grounded, and safe to use, helping prevent shocks, shorts, or other electrical issues in your home.

Why did only one outlet stop working?

If a single outlet stops working, it’s usually caused by a loose connection, a faulty part, or a wire. While it might seem minor, it’s important to have a licensed electrician check it. Fixing the problem early ensures your outlets stay safe and reliable, and helps prevent bigger electrical issues in your home.

How much does it cost to install or replace a light switch near Raleigh?

The cost varies depending on the type of switch and the complexity of the installation. Replacing a standard single-pole switch typically runs $75 to $150, while dimmer switches cost $100 to $200 installed. Smart switches usually cost $125 to $250, including installation. Three-way or four-way switches cost more due to additional wiring complexity. We provide upfront flat-rate pricing before starting work.

Can I replace a light switch myself, or should I hire an electrician?

While replacing a simple single-pole switch is straightforward for someone with electrical experience, we recommend hiring a licensed electrician for safety and code compliance. Improper wiring can create fire hazards or cause the switch to fail. Dimmer switches, smart switches, three-way switches, and any work involving new wiring should definitely be handled by a professional to ensure everything works properly and safely.

How long do light switches typically last before needing replacement?

Quality light switches usually last 30 to 40 years with normal use, but high-use switches in busy areas may wear out sooner. Factors like poor installation, power surges, and frequent on-off cycling can shorten switch lifespan. Even if switches still work, upgrading to modern switches with better features, improved safety, and current styling is worth considering after 20-25 years.

Why is my switch or outlet hot?

A switch or outlet feeling warm can be caused by a built-in heat source or a potential electrical issue: Dimmer switches: Many dimmers have a small heat sink built in to dissipate heat from the bulb. It’s normal for these to feel slightly warm during use. Overloaded circuit or faulty wiring: If a standard outlet or switch is hot, it could indicate too much current flowing through, loose connections, or worn components, which can be a fire hazard. Slight warmth on a dimmer is normal, but any significant heat on a standard switch or outlet should be inspected immediately by a licensed electrician. Safety first!

How much does it cost to install a generator near Raleigh?

Whole-home generator installations typically range from $8,000-$15,000 including the unit, transfer switch, concrete pad, fuel connections, and labor. Portable generators cost less upfront, usually $500-$2,000 for the unit plus $300-$1,200 for transfer switch installation. The final cost depends on generator size, installation complexity, and any necessary electrical work. We provide upfront pricing after evaluating your specific situation.

What is CSST bonding?

CSST stands for corrugated stainless steel tubing. CSST bonding is the process by which the gas piping system is intentionally installed to the grounding electrode system. This creates a lower resistance way for electricity to connect with the earth, giving ground fault protection to a gas line and making it safer for a home’s residents.

How much does it cost to ground a gas line near Raleigh?

To ground a gas line will typically cost between $100 – $300, depending on the individual circumstances of how it was originally installed. For a more accurate price estimate, contact Dawson’s Electric today, and we will be happy to assist you.

Why is the proper installation of a gas flex line so important?

Proper installation of a gas flex line, or CSST gas line, is crucial to the safety of a home. If not properly bonded, CSST lines are susceptible to damage from lightning strikes and could cause a house fire. During a lightning strike, energy can run through wiring into a house, then jump onto the gas flex line. The extra surge can cause damage to the line in the form of tiny holes, letting gas escape and potentially causing fires. Proper bonding of the gas flex line will prevent this from happening.

My Chapel Hill home is nearly a century old. Does the wiring need to be replaced?

Not always all of it, but it deserves a professional assessment. Very old homes can carry early wiring methods and ungrounded circuits that don't meet modern safety standards and can complicate insurance. Sometimes targeted updates, grounding key circuits, replacing degraded sections, and modernizing the panel are enough; sometimes a more complete rewire is the right long-term call. We assess what's actually in your walls and give you a straight, prioritized answer rather than assuming the worst or glossing over a real issue.

Can I upgrade my electrical panel in a historic-district home?

Yes . A panel upgrade is usually about the equipment and service capacity rather than the home's protected exterior features, so it's typically very doable even in a historic district. We plan the work to be unobtrusive and to meet current code, and where a historic designation adds requirements, we work within them. For most older Chapel Hill homes, upgrading from an undersized older panel is the single most valuable and enabling electrical improvement you can make.

Do I need a service upgrade before installing an EV charger?

Often, in an older home, yes . A Level 2 charger draws significant power, and many older Chapel Hill homes have a panel that's already near capacity. Forcing a charger onto an overtaxed panel is both a code and a safety problem. We check the panel first, size the charger correctly for your vehicle, and handle any needed service upgrade as part of the same job, so you end up with charging that's safe and properly supported rather than improvised.

Is knob-and-tube or old wiring in my home a fire risk?

Aging wiring isn't automatically dangerous, but it warrants professional evaluation because older methods lack modern grounding and can degrade at connections over many decades. The risk depends on condition, past modifications, and load. We don't recommend ignoring it or assuming a previous owner handled it. We inspect it, tell you what's safe to keep and what should be updated, and prioritize the work so the most important safety items come first.
