Family-owned Same Day Heating, Cooling, Plumbing offers fast, reliable AC repair and installation services, heater repair & installation, and now plumbing services, in San Diego County. Our promise to you is always that if we do not fix your system the SAME DAY we arrive… you DON’T pay the service fee. Our home service experts are licensed and insured with more than 100 years of leadership experience. Additionally, we back all of our installation and replacement services with a 24-month, 100% satisfaction guarantee.

"This place is a scam- DO NOT TRUST THEM! Just pay the extra and work with a BBB accredited company. We are extremely dissatisfied with the service we received today. We hired someone to save us time during a large demo project, but wish we just did it ourselves from the beginning to save time and headache. Based on the company's assessment, we were informed that our dryer vent had a significant blockage, so severe that it would require tearing out walls or possibly going through our new roof. We were obviously concerned about the potential cost and disruption. But don't worry, they're a construction company too... a little too convenient However, after the technician left, my husband decided to inspect it himself since we just had it cleaned within a year ago. Within an hr, he was able to clean out a considerable amount of lint, but there was no actual blockage obstructing the vent. In fact, as you can see in the attached photograph, a standard dryer vent cleaning tool could pass straight through the hose from the front to the back. Not to mention, there is plenty of air coming through the vent and none coming back into the home."

Heating Oil questions, answered by experts

Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.

Service costs range from $200 to $1,500, depending on maintenance needs, system age, and labor.

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

You can expect a geothermal system to last for years. According to the Department of Energy, the underground infrastructure for the heat pumps lasts about 25 to 50 years, which includes the pipes buried in the soil. The actual heat pump itself has a life span of around 25 years.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.
