"I had Triangle replace my hot water heater because they were able to do the job the soonest. With that, they gave me 2 HVAC inspections for free. When the service person, Ryan Peters, came to do my inspection, I was told I had a freon leak somewhere, my unit was freezing up, it was running at 30% efficiency, and I would need a whole new A/C unit and furnace for the cost of $20K. He told me there was no reason to fix it because it was 17 years old and it would be extremely expensive to find the leak. When I called later to ask for that info. so I could get a second opinion, the story changed to, "you MIGHT have a leak", and they were reluctant to give me any of the information he told me the day prior. I was having no issues with my A/C, so I hired another HVAC professional with extensive experience. He came and told me he just needed to add freon for a minimal expense. My A/C is working perfectly. This company was bought out by a big corporation and it's all about $."

Heating Oil questions, answered by experts

Yes, many providers offer organic or eco-friendly treatments. Confirm availability with your contractor.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.

Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.
