Mark was fantastic, responding promptly and scheduling a visit the very next day. He accurately identified the issues and clearly outlined the necessary work, avoiding unnecessary upselling. His professionalism and transparency earned our trust. We highly recommend Mark for any air conditioning repair needs.

We were without air con for a week, which was extremely uncomfortable inside. The United Heating & Cooling team arrived promptly on a morning visit, replaced the old system, and had the new one up and running by afternoon. They worked efficiently, being mindful and courteous throughout. As they explained their work, I appreciated their friendly demeanor. They ensured I understood the guarantees and what's involved in regular maintenance. Without hesitation, I'd recommend these service professionals to anyone needing heating or cooling assistance.

Their professionalism is impressive - they took the time to meet with me at both my home and rental property, explaining options and ensuring I was happy with the work and cost.

The technician arrived promptly the next day and addressed the issues with my AC system. Erick did an excellent job, answering all our concerns and providing clear explanations. His professionalism was impressive, making the experience seamless. I'm grateful for the reliable service and can't overstate how much it helped during a stressful time of selling our home.

The repair of the portable A/C unit was prompt and thorough, delivering a cool environment that met our needs. The technician demonstrated exceptional skills, streamlining the process entirely.

Scheduled service arrived between 11am and 3pm, but the technician didn't show up by 3pm. No call or email/text was made to inform us of the delay.

It's unclear how a job can be delayed by 4 hours within our allocated time frame without any communication. Either they're scheduling multiple jobs simultaneously or their customer service is severely lacking.

The technician called after we followed up, saying he was on his way but didn't provide an estimated arrival time or give us an idea of how far away he was. This lack of information makes it difficult to plan for the wait.

We have schedules and lives to attend to. The company's failure to communicate delays effectively is a major issue that needs attention.

Very dissatisfied with the experience.

I've relied on Frontline for all my household essentials - heating, cooling, plumbing. I've had them handle maintenance, installations, repairs, even two burst pipe issues. Their work is top-notch and reliability is key. However, their customer service truly sets them apart. They're punctual, courteous, and genuinely personable. The prices are more than reasonable too. That's why I stick with Frontline - they've earned a loyal customer in me.

They arrived quickly and provided a quote on short notice. The technician was prompt and exceeded expectations by fixing both the blown motor and the faulty thermostat without charging for the additional work, which wasn't required. Overall, their service impressed me greatly.

Excellent experience with this company. Fast installation of our new boiler left us delighted and grateful for the pleasant interaction.

Jared did a fantastic job. His punctuality impressed me - showing up ahead of schedule. He explained the problem with my unit clearly and resolved it promptly. His professionalism earned him extra points, and I'll definitely be back for future services.

I'm glad I picked them for my annual maintenance. The technician was knowledgeable, explained what he did clearly, and presented himself professionally. He even offered tips on keeping the system running smoothly, which is more than I expected from a routine visit.

We've relied on this company for our HVAC needs for several years now. The technician was diligent, friendly, and knowledgeable. Their annual maintenance visits are thorough and attentive to even minor problems. They truly stand out in their field - I'd highly recommend them to anyone looking for reliable service.

Jared came out because we heard a weird noise from the furnace. He couldn't recreate it when he checked, but he was still pretty thorough about explaining what he was doing and answering our questions. Overall, we're looking to get a new heating system installed soon and are glad Jared is part of the process.

The representative from this company exceeded my expectations during the consultation. They presented multiple options and clearly explained the benefits and potential cost savings. I was impressed by their ability to present data in a clear and concise manner, which helped me make a well-informed decision about my home services needs.

The company delivered prompt and polite service. Their technician provided an in-depth explanation of the filter problem. The use of a soft-bristled brush for cleaning was particularly effective. The installation was secure, and all components were correctly aligned. Excellent job.
