AC Repair Services in Dover, NH

When your air conditioning system breaks down during the sweltering New Hampshire summer, you need fast, reliable service from technicians who understand the urgency of your situation. At Paul the Plumber, we specialize in comprehensive AC repair services throughout Dover and surrounding communities. Our team of licensed technicians brings over two decades of experience to every repair job, ensuring your cooling system returns to peak performance quickly and efficiently.

Dover residents face unique challenges with their cooling systems due to our coastal climate and temperature fluctuations. The combination of high humidity from the Piscataqua River and temperature swings can put tremendous strain on air conditioning units. We’ve serviced thousands of homes in the Seacoast region, giving us invaluable insight into the specific problems that affect AC systems in our area. From refrigerant leaks caused by salt air corrosion to compressor failures due to power surges during summer storms, we’ve seen and repaired it all.

Common AC Problems We Fix

Understanding what goes wrong with air conditioning systems helps homeowners recognize when professional repair is necessary. One of the most frequent issues we encounter involves refrigerant problems. Your AC system relies on precise refrigerant levels to cool your home effectively. When leaks develop in the refrigerant lines, often due to corrosion or vibration damage, your system loses cooling capacity gradually. We use advanced leak detection equipment to pinpoint even the smallest leaks, then perform permanent repairs and recharge your system to manufacturer specifications.

Electrical component failures represent another major category of AC repairs. Your air conditioner contains numerous electrical parts including capacitors, contactors, relays, and circuit boards. The run capacitor, which helps the compressor motor start and run efficiently, frequently fails after several years of service. When this component weakens, you might notice your AC struggling to start, making humming sounds, or shutting off unexpectedly. Our technicians carry replacement capacitors for all major brands, allowing us to complete most electrical repairs during the initial service visit.

Our Diagnostic Process

When you call Paul the Plumber for AC repair in Dover, we follow a systematic diagnostic approach that ensures accurate problem identification and cost-effective solutions. Our process begins with a thorough visual inspection of your entire cooling system, including both indoor and outdoor components. We check for obvious issues like dirty filters, blocked condensate drains, or visible damage to components. This initial assessment often reveals simple problems that homeowners might overlook but significantly impact system performance.

Following the visual inspection, we perform comprehensive electrical testing using professional-grade multimeters and specialized HVAC diagnostic tools. We measure voltage and amperage draws on all major components, test capacitor microfarad ratings, and verify proper operation of safety switches and controls. Temperature measurements across the evaporator and condenser coils help us assess heat transfer efficiency and identify potential airflow restrictions or refrigerant charge issues. By gathering this detailed diagnostic data, we can provide accurate repair recommendations backed by concrete measurements rather than guesswork.

Repair vs. Replacement Considerations

As a family-owned and operated business serving the community for 22 years, we believe in honest recommendations that serve your best interests. Sometimes, repairing an older AC unit makes perfect financial sense, while other situations clearly call for replacement. We consider several factors when advising customers on this important decision. The age of your system plays a crucial role – air conditioners typically last 12-15 years with proper maintenance. If your unit approaches this age range and requires expensive repairs, replacement might offer better long-term value.

We also evaluate repair costs against replacement benefits using industry-standard calculations. Generally, if a repair costs more than 50% of a new system’s price, replacement becomes the wiser investment. However, we consider your specific circumstances, including budget constraints and future plans for your home. Our upfront pricing policy means you’ll know exact costs before any work begins, and our BBB A+ rating reflects our commitment to transparent, ethical business practices. Whether you choose repair or replacement, we back all our work with a comprehensive 2-year parts and labor warranty, with an optional 3-year warranty available through our club membership program.

Emergency AC Repair Services

Air conditioning failures rarely happen at convenient times. When your AC stops working during a heatwave or humid spell, every hour without cooling feels unbearable. We prioritize emergency repair calls, understanding that comfort and health concerns make rapid response essential. Our licensed technicians maintain fully stocked service vehicles with common replacement parts for all major AC brands, enabling us to complete many repairs immediately without waiting for parts delivery.

Our emergency repair service extends beyond simple fixes. We’ve responded to complex situations including complete system failures, refrigerant leaks causing ice formation, and electrical problems creating safety hazards. Each technician undergoes thorough background checks and continuous training on the latest repair techniques and safety protocols. When we arrive at your Dover home for emergency service, we work efficiently to diagnose the problem, explain our findings clearly, and implement lasting repairs that restore your comfort quickly.

Maintenance Prevents Costly Repairs

Through our thousands of verified 5-star reviews across multiple platforms, customers consistently praise our emphasis on preventive maintenance. Regular AC maintenance dramatically reduces the likelihood of unexpected breakdowns and extends equipment lifespan. During maintenance visits, we perform essential tasks that homeowners often cannot complete safely or effectively:

  • Coil cleaning: We thoroughly clean both evaporator and condenser coils, removing dirt and debris that insulates these heat transfer surfaces and forces your system to work harder
  • Electrical connection tightening: We check and tighten all electrical connections, preventing resistance buildup that causes component failures and potential fire hazards
  • Refrigerant level verification: We measure refrigerant charge precisely and check for leaks, ensuring optimal cooling efficiency and preventing compressor damage

Professional maintenance also includes lubricating moving parts, checking and adjusting blower components, testing thermostat accuracy, and inspecting ductwork connections. These proactive measures catch developing problems before they cause system failures, saving money and preventing inconvenient breakdowns.

Michele

I’ve used Paul the Plumber twice now for electrical issues and they have been wonderful each time. They are fast, polite, knowledgeable, and very fairly priced. They explain everything well and answer my questions thoroughly and I feel safer now knowing what was causing my electrical issues and having it fixed! I will be using Paul the Plumber for all my household needs going forward

V. Vincze

We had an issue with our water…too hard, calcium deposits, and very little pressure in our master bathroom shower only. The techs (Mike E. & Tyler S.) arrived right on time. They were friendly and very personable. After installing our whole house filtration system and successfully finding the issue with our master bathroom, they left the work areas in pristine condition. They were meticulous in their work, and I highly recommend them for any plumbing needs!

T. Minasian

These are the after photos of the Rinnai tankless water heater installation and vent to the outside. It was important to me that the crew was able to use the existing vent hole to the outside to run both the intake vent pipe and the outside vent pipe. It made the job very clean and did not change the appearance of the outside wall. A shout out to Mike E, Caleb, Josh & Corey

J. Wojo

DJ from PTP was incredibly helpful and knowledgeable. My shower was not draining and it became a bigger project than I thought it would and they came out quickly and were able to fix my problem. Then when my water heater had a slow leak they came back out quickly to attend to it and fix my problem. I really appreciate their hard work. Thank you so much!! Would definitely recommend them.

D. Lefort

Arrived as scheduled to fix a leak from the shower valve. Tried to fix old 30 or 40 year old unit but had to replace with a new one. Quality work, parts and cleaned up when they were done. Would definitely use again.

S. DesMarais

Josh was amazing. He was able to install my ring doorbells with no issues. He also did a great check of my homes smoke detectors and a few electrical plugs. He was thorough, Knowledgeable, and easy to work with. I would definitely use them again.

M. Richdale

Thanks to Mike Vallee from Paul the Plumber for responding to this new customer’s call so quickly. He was courteous, thorough, explained the repair he was doing and left the work area spotless. I highly recommend Paul the Plumber (and Mike!) to anyone looking for a reliable plumbing company.

S. Baraket

Never used Paul The plumber company before but I’m glad I did. Very courteous, professional and pleasant from the answering service (Diane) to employees (Jeremy). They diagnosed the problem and fixed it in no time. Very happy and satisfied with their service. Definitely will use again. Thank you

Nick Boudreux

Had a well pump that was shorting out and pretty much had no water. Adrian from this company not only got out next day but was great to work with. He was very friendly and knowledgeable I would definitely recommend this company to anyone that needs work done! Thanks again guys!

W. Chepren

I made an appointment on line the morning of July 31 and two trucks showed up at 1:00 pm right on time that same afternoon. Both guys were friendly and very knowledgeable. They quickly found the source of the wet patch on my ceiling which wasn’t the plumbing but a problem with the shower curtain. This is the second time I have called Paul. Both times I got outstanding service and will always call on Paul the Plumber for any plumbing problems in the future. Very reasonable cost for the visit.

H. MacPherson

I would recommend Paul the Plumber 100%. They offered same/next day service. They were friendly, professional and quick – from the office staff to the technicians. Overall an amazing experience from start to finish.

D. Weaver

What a fantastic business. Helped us work with our water district in resolving meter replacement issues. They also fixed a pipe leak that had developed over time. Caleb was wonderful and answered our questions as well as working with the water district engineer on the meter issues. So easy to work with.

D. Marchand

I cannot say enough about this company!!! Their only concern is that you are up and running again with no worries. I’ve had Kyle the plumber, and Josh their electrician out here and both are polite, well trained and you can tell they truly care about getting you back in service. Great service, well trained caring staff! I will never go anywhere else!

K. MacCallum

First time customer, and am very pleased with the whole experience. The highlight was definitely with the technicians assigned to the job and their work – Tyree and Corey were clean, polite, well-informed, and very helpful with some of the questions I had along the way. Their work appears to be top-notch, and they made sure no mess was left behind. Will definitely be calling and requesting these two again on any future needs.

J. Shea

John was wonderful. He found the problem right away and fixed it. He checked other outlets just to make sure I would be safe. He explained different programs the company offers also. I’m very happy.

K. Bernardo

We’re first time home owners and needed help with some plumbing and adding a filter system. They were able to get a technician scheduled to our house within a day or so of me contacting them. Mike was super helpful and was able to complete all the jobs in a timely manner, and also cleaned up the areas he was working in. Overall a great experience and would definitely use them for future jobs.
