Whole House Surge Protection

Dor-Mar electrical services

Protect Your Home from Costly Electrical Surges

Power surges can damage appliances, electronics, and smart home devices, leading to expensive repairs or replacements. A whole house surge protection system safeguards your home from sudden voltage spikes caused by lightning strikes, power grid fluctuations, or internal electrical issues.

At Dor-Mar, we provide professional whole house surge protector installation to help homeowners prevent costly electrical damage and keep their homes safe.

What Causes Power Surges?

Power surges happen when there is a sudden increase in electrical voltage. Common causes include:

⚡ Lightning Strikes – A nearby lightning strike can send a massive surge through your home’s wiring.
🔌 High-Powered Appliances – HVAC systems, refrigerators, and large appliances can cause internal surges.
🏢 Utility Grid Issues – Power outages, surges,  transformer failures, and fluctuations in the power grid.
🔋 Wiring Problems – Faulty or outdated wiring can increase the risk of surges.

Why You Need Whole House Surge Protection

A whole house surge protector blocks or diverts excess electricity before it can damage your appliances and electronic devices. Key benefits include:

✅ Protects Expensive Electronics – Prevent damage to TVs, computers, gaming systems, and smart devices.
✅ Extends Appliance Lifespan – Helps HVAC systems, refrigerators, and other appliances last longer.
✅ Increases Home Safety – Reduces the risk of electrical fires caused by voltage spikes.
✅ Protects the Entire Home – Unlike plug-in surge protectors, whole house systems protect all outlets.

Terri GuoTerri Guo ★☆☆☆☆ We paid the yearly maintenance fees, they didn’t do the maintenance at all only charged for the money, the maintenance guy said my furnace need to put a UV light to kills the moisture, when he came he told me our water heater need to be replaced and he said if we buy the water heater from them he’ll install the UV LIGHT for free at least 50% off, and clean it for free. After we replaced the water heater they didn’t do it, we still paid a lot money for the UV LIGHT and they didn’t clean it at all so DisappointedResponse from the ownerWe appologize that you have had your maintenace reasxheduled a couple of times Terri, unfortunely with the heat wave we expirienced all working units had to be moved off of the schedule to take care of people without working ACs. As far as the UV light our record indicates extensive notes on where we installed a UV light at one of your properties and that you canceled the one for your home address. If you wish to further discuss your issues you may reach out to our office. Dorothy McCulloughDorothy McCullough ★★★★★ Trevor did an awesome job. He was so professional and nice.Response from the ownerThank you for leaving your tech a great review! John MJohn M ★☆☆☆☆ We experienced some mixups with their after hours phone service but then finally the tech shows up and says "I called my boss and we don't service geo-thermal systems" When we explicitly told them that is the system we had and they show on their web site as servicing/installing geo-thermal. in the end it was just a run around and ended up going with another company that worked out great.Response from the ownerWe apologize for the miscomunication John, we are currently working to correct the issue with our Live Services to further inform them on vthe types of units we do not service. We have also double checked our services lsited on our website and Geothermal units are not on that list. Again we apologize for the miscomunication and are working to ensure this doesnt happen again. Josh HarshbargerJosh Harshbarger ★★★★★ Anthony was so great! Polite, knowledgeable, and efficient.

Josh PratherJosh Prather ★★★★★ Good all around.Response from the ownerThank you for the 5-star review Josh! Lee annLee ann ★☆☆☆☆ DorMar does my sister’s HVAC and she has a yearly maintenance contract. SHE is unable by phone or text due to an illness. DorMar came out 3 times during my time as my sister’s Personal Home Manager and POA (in writing). A supply vent has mold and now and they are refusing to come to investigate and/ot provide a quote to fix this serious problem on their work. Even with my sister’s permission in writing and agreement to pay DorMar - they refuse to come to investigate mold on a supply register. Delaying service is going to make it worse and could be deadly.Response from the ownerUnfortunetly Lee, when it comes to scheduling services outside of the maintenace agreement that has been paid for by your sister we have to have consent straight from your her or a legal document stating you are POA and can make decisions for the property. Our system tracks every phone call and we have it on record that on 6/27/2025 in a phone call between you and one of our CSRs that you are not POA this means you are not able to schedule these appointments. Legally we are not able to schedule anything without that documentation or consent straight from your sister. If you are able to provide either of those we will be happy to schedule a service to inspect the issues going on in the Ductwork/HVAC in the home. WAYNE LWAYNE L ★☆☆☆☆ My ac stopped working this evening. This company claims 24 hours service but reluctant to provide service for 2 days. What happened to prompt service? The lady on the phone couldn't speak clear English. This company claims prompt service but fails to do so.Response from the ownerUnfortunetly Wayne with the heat wave we have had this past week our schedule has been booked a couple days in advanced for this entire past week. We always try our best to do same day service but our schedule can still book up. Dorothy MoorheadDorothy Moorhead ★★★★★ Service call yesterday for issue of short run and inefficient cooling after being inspected 3 weeks ago and deemed in good working order resulted in discovery of king valve being mostly closed and starving system of coolent then the system being bleed down to where it had to be shut down due too tech having trouble disconnecting equipment (reverse threads) .As tech didn’t have coolant on His truck - received text schedule for today between 8-12 to recharge the system - now 1:25 and still waitingSean GradySean Grady ★★★★★ DorMar was quick to respond during a heat wave for my AC being out. The tech (Greg) was quick and professional. Thank you!Response from the ownerThank you Sean for leaving a great review about your expirience! Ken NethersKen Nethers ★☆☆☆☆ My girlfriend had their so called tech come to the house 6/21 /25, he trampled her flowers just to break his meter out and tell her your ac is fried, $7000 to replace, called her nephew the next day, he fixed a burnt wire end ( it gave no reading), trimmed it and bam works like new. They charged $250, to work 10 minutes , trample flowers and leave everything unhooked. Never again will they rob me of my money or time, lousy tech and service. Ps ac is 1997 works fineResponse from the ownerWe apologize that you had such a poor expirience with our technician, we are currently dealing with the issue to ensure it doesn happen again. We appreciate the honest feedback and letting us know what went wrong with your appointment. Yalin LiuYalin Liu ★☆☆☆☆ Worst customer service. Been understanding and trying to work with their schedule, rescheduled my paid maintained twice already, when they called third time to reschedule I refused. their response is nothing they can do. And they can’t refund my money. Not recommended.Response from the ownerWe are sorry you have been rescheduled more than once Yalin, unfortunetly with the heat wave we have expirienced since last week we have had an abundant amount of non working units on our schedule, and being short staffed we are trying our best to keep Prevantative maintenaces scheduled when we can but we arent always able to keep working units scheduled. S HawkinsS Hawkins ★★★★★ Anthony was greatResponse from the ownerThank you for leaving our tech a great review! Rupal ShahRupal Shah ★☆☆☆☆ Horrible customer service. Worse follow through. Poor Management and Leadership.We called Dor Mar because we were having issues with our heater. Here is a timeline of what happened on the days they came:--Feb 21: They came but the technicians didn't do anything because they didn't know what to do.--Feb 26: They came and broke the heater. They admitted to it, which led to further issues. The bigger issue is that we had no heat after that for several days. I called Dor Mar three times after that to get them to urgently come and make repairs.--Feb 28: They said they would come and fix the issues but no one from Dor Mar came. So I called again.--Mar 1: A technician came and started to fix things. At that time, gas started leaking and smelling throughout the house. Therefore, he stopped the work and left the house. So i called again and asked for someone to come who knows what they are doing.--Mar 3: They finally came and fixed the issues. Heat didn't start working again until Mar 3.During that time frame, employees Dave, Trevon, and Brad from Dor Mar because each of them worked on our house and not only did it take several tries, in between that time it caused us inconvenience from Feb 21 to Mar 3 because we didn't have heat and the day of the gas leak we had to open all windows/doors in the entire house and air it out. This was all happening during a time when the weather was cold!!!I called their operations manager 3 times with no response and emailed them 2 times with no response. I would pay the bill but I was asking for a discount or some compensation for the gross negligence caused by lack of heat, and gas leakage. They provided no discount, no apologies for the issues caused, and no response to any of my inquiries.To this day, no one called me back. No one emailed me back. Instead, they kept sending me invoices every few days for the full amount to pay them which was close to $2000.I am disappointed in their customer service. I would summarize them as have poorly trained technicians and staff, and even worse management and leadership etiquette. I would never recommended them and hope people read my review before considering them.G MG M ★☆☆☆☆ We have been a customer for over 20 years and they have gone to trash over the past couple of years. Billing for services not rendered, not taking care of warranty issues, improper installation practices, up charges due to their own improper installs that do not match manufacture's requirements for warranty. Even the techs they send out says that service manager (Cody) and operations department (Stacy) are a large part of the issue. Had techs sent out multiple times and service gave them improper reason why they were here. Then argued with tech audibly that what the tech observed was incorrect. This happened on more than (5) service calls about our faulty water heater they installed. Called and spoke to management and was promised an audience with the Operations Manger regarding our issues, never happened. There are many companies that provide the same services and will not try to defeat your trust and wallet at the same time.Response from the ownerWe are sorry that you have had such a poor expirience with us, we will be sure to review everything in the account to ensure these issues do not continue to happen Bobby AdamsBobby Adams ★★★★★ Response from the ownerWe appreciate you leaving us a 5-star rating Bobby! Thank you for choosing Dor-Mar Home Services! Jayne BryanJayne Bryan ★☆☆☆☆ I have given DorMar 5 stars in the past, so I'm not sure what has changed but it's not the same. I have a 3 yr service contract which includes hot water tank, furnace & AC check once a year. The last 2 years had gone well until today. I was unaware they now have plumbers that check only the HW tank. It was not communicated that only the HW tank was to be done today. In the past 2 of the 3 services were done together. I purchased a new HW tank on 5/19 & I didn't need it checked. I was also offered a randon test but "no randon kits on the truck." My HW tank was not purchased from DorMar because when my garbage disposal broke & needed replaced, I was quoted $900.00 over the phone.The disposal was replaced by a plumbing co. for 120.00. We are purchasing a new furnace & AC next year & it won't be through DorMar. Unfortunately, I won't even be finishing out my contract. The only positive was Anthony who was extremely nice & apologized numerous times for the misunderstanding. Definitely not his fault.Response from the ownerWe apologize for the misunderstanding Jayne, looking into the history of your account our records indicate that the last couple of years you have recieved your plumbing inspection and your furnace inspection at the same time. Our system tracks every call we take and unfortunetly there was never any mention of the AC inspection being scheduled along with , but we were happy to get you on your next available day for the inconvienience and misunderstanding which the offer was declined. We are sorry to hear you are unhappy with the company, but glad your expirience with the tech went well. Linda M. DavisLinda M. Davis ★☆☆☆☆ $900 outdoor garage faucet- we had a leaky faucet. Called DorMar- plumber came out fixed it and charged us $150 for service call and $750 for a new faucet. It seems like a steep price to fix it. Needless to say we will not be calling them in the future.Response from the ownerWe are sorry to hear that there was an issue with our pricing Linda, unfortunetly we arent in control of how high the prices have gotten. We also have a strict policy on all work that is preformed here at Dor-Mar. The pricing for a service call is discussed at time of booking, and the worked that was preformed was quoted and signed for before completion. izzy4usa Thomasizzy4usa Thomas ★☆☆☆☆ i wanted central air so i called them because of their experience of 62 years.they came and said i needed a new furnace too i paid 9k. they installed a furnace bigger than the one they to0k put so i have had nothing but problems from them. the furnace sounds awful and now all my ductwork is rattling becuase it fit a smaller furnace. they want me to pay u- fromt to come again but i have lost count as to how. many times they have come out. here so i will be calling another company to make corrections on this terri le excuse for hvac!! dont waste your time with dor mar also their office pady os nastyBryn SmathersBryn Smathers ★☆☆☆☆ Make sure prior to the job you discuss price, process and have it in writing. Our hot water tank needed a new valve which was covered under warranty. Our service maintence package with Dor Mar covered the first hour of labor for the repair. They sent me a bill for the hour labor it took them but I was told it was covered. Very discouraged by this and will be cautious with the next repair. Not good practice especially to a customer who bought the hot water tank through Dor Mar.Response from the ownerUnfortunely we are at the mercy of the manufacturer when it comes to what is covered under warranty, we are sorry that it was not discussed prior to your repair call that you would owe the labor to put the part in, standard protocall includes a phone call from our parts department to discuss costs before hand. Our records indicate you had discussed the price for the parts call before excepting the estimate for the work. Your labor for the Daignostic call was covered under your Service Contract. We appologize for any misunderstanding and hope you continue with Dor-Mar!

Elijah WilliamsElijah Williams ★★★★★ Dor Mar hires great prospects who provide excellent service. My tech, Preston, came and knocked the job out of the park — I’ve had 3 different companies come out and inspect my heat pump several times but we got no where. Wasted money and wasted time.Not only did Preston diagnose the problem on the first visit, he explained everything well enough for me to understand what needed to be done, ordered the parts and had my AC running the next week — Very satisfied! 10/10Response from the ownerWe truly appreciate you leaving a thoughtful review for our technician Elijah. Thank you for taking the time out of your day to provide such wonderful feedback!

What they lack in knowledge they make up for with deceit.Response from the ownerUnfortunately we are not able to locate you in our system, we would like to look into the service you had done to see how we can improve. Please reach out to our Customer Satisfaction Manager kayden@dormarhvac.com or call into the office and ask for her directly so we may get to the bottom of this. Juanita RamseyJuanita Ramsey ★☆☆☆☆ Dor Mar sent out a employee to drain my hot water heater as part of a maintenance program that I paid for. That employee spent most of the time walking around the inside of my house (my hot water tank is in the basement with an outside access only) taking pictures of all of my plumbing. He did not ask to do this he just started taking pictures saying he was supposed to. He opened my cabinet under my sink and wanted to know why I had a bucket there. (it was to carry cleaning supplies in when cleaning around the house)Then he told me that there was a problem with my tank since he emptied it and it was leaking. I asked him how much it would cost to fix it and he immediately said $2700.00. I told him just to turn the water off to the tank and to just leave. He had placed a bucket under where it was leaking, and he said I won't have hot water. If he turned it off. He then tightens the screw a little more and then it quit leaking.Another problem I had was I told him he could park beside the house (I showed him where) but for some reason he just wanted to walk through the front door and through the house and then out the back door. He did this about 3-4 times.Finally, when he was done, I opened the gate so that he wouldn't walk through my house again and he went straight to the front door saying he was so sorry, but he had lost all of the pictures that he took and had to come in to retake them all again. At this point I was ready to call the sheriff to escort him off the property. I did let him take the pictures and finally he was off.He was polite when talking to me I have no issues there, but all the other stuff was unnecessary... He was there to drain my hot water tank not to do a photo shoot. I will try to come to the office on Monday I am still extremely upset about this. IT IS NOT THE WAY TO DO BUSINESS!Response from the ownerFrom your description of what the technician did while in your home perfectly describes our Plumbing maintenance Juanita. The plumbing maintenance includes a check on the entire plumbing of the home and the flushing of your hot water tank, we do apologize if that was not properly explained to you when your service was booked. It is also unfortunate the tech couldn't follow the directions you offered to not have to walk through the home and we apologize for that, over all we hope this gives you some ese on what was done by the tech as he was just doing his job. Angela SeymourAngela Seymour ★★★★☆ The service was great. But they don't honor their service windows. My service windows was 12-4 and I get a message at 9:40 that the tech was on the way. I had to rearrange my schedule to fit in the cleaning. Luckily I was close by and could make it to the house in time.Response from the ownerWe apologize there was an issue with your scheduling, we always try our best to make our time frames, in the future wed be more than happy to have the Tech wait for the scheduled time frame had we known it was an issue for you to make the appointment earlier. Chuck DunfeeChuck Dunfee ★★★★★ Response from the ownerWe appreciate the 5-star rating Chuck! Faith NeibargerFaith Neibarger ★★★★★ Response from the ownerThank you for the 5-star review Faith! Tara BeyerTara Beyer ★★★★★ Response from the ownerThank you for the 5-star rating Tara! junior pjunior p ★★☆☆☆ Techs are great and do a very good and thorough work, but their billing and customer support will rip you offResponse from the ownerIts unfortunate that you had an experience with our customer service reps that made you feel that way, If could you please reach out to the head of our Customer satisfaction team to provide some more details on your situation so we can better ensure it doesn't happen again it'd be greatly appreciated. You may reach her by email - kayden@dormarhvac.com or call our office @ 740-345-6639 and ask for her directly.

I cannot say enough good things about them.Response from the ownerThank you so much for taking the time to provide such wonderful feedback about your experience with out team!
