Heat Pump Installation & Repair

Heat pumps provide efficient heating and cooling from a single system. We install and repair all heat pump types with the expertise needed to diagnose unique components and deliver reliable year-round comfort.

How It Works

A heat pump is one of the most efficient and versatile comfort systems available — capable of both heating and cooling your home using a single unit. When a heat pump starts underperforming, making unusual noises, struggling to maintain temperature, or failing to switch between heating and cooling modes, the cause needs to be properly diagnosed before any repair work begins. Our technicians perform a full system inspection covering the refrigerant charge, reversing valve, compressor, coils, electrical components, thermostat, and airflow to identify exactly what is causing the problem. For new installations, we evaluate your home's layout, existing ductwork or ductless configuration, climate demands, and efficiency goals to recommend the right system and size for your specific situation. We then handle the complete installation — from removing old equipment to final testing — ensuring the system is operating correctly and efficiently before we leave.

The Benefits

Year-round comfort from one system — A heat pump heats in the winter and cools in the summer, eliminating the need for separate heating and cooling equipment. One system, one maintenance schedule, and one contractor handling it all.

Exceptional energy efficiency — Heat pumps move heat rather than generate it, making them significantly more efficient than traditional heating systems. Homeowners who switch to a heat pump often see a noticeable reduction in their monthly energy costs, particularly on the heating side.

Accurate diagnosis for faster repairs — Heat pump systems have unique components like the reversing valve that require specific knowledge to diagnose correctly. Our technicians are trained on heat pump systems specifically, ensuring the right repair the first time rather than trial and error.

Works in San Diego's climate — Heat pumps perform at their best in mild climates like San Diego's, where extreme cold is rarely a factor. If there was ever an ideal environment for a heat pump system, this is it.

Ductless options available — If your home doesn't have existing ductwork or you want to add heating and cooling to a specific area, we install ductless mini-split heat pump systems that deliver precise comfort control without the need for ducts.

Long term reliability with proper installation — Like any HVAC system, how a heat pump is installed directly affects how long it lasts and how well it performs. Our technicians install every system to manufacturer specifications, protecting your warranty and setting your equipment up for a long reliable service life.

Hey Leon, thank you for being such a great plumber and coming out to our office building and handling the smell that was going through the hallways! We had several tenants complaining about a smell of sewage in our office building and we’ve had two plumbers come out and could not figure it out. Leon With By The Book Plumbing came and he literally just poured some water in a floor drain and the smell stopped. It was a five minute repair for him where other people were trying to charge us like three grand to open up walls and see what they could find. He didn’t even charge us! So I’m writing this review. If you’re looking for an honest Plumbing Company By The Book is the one

Leon was absolutely outstanding. Professional, honest, and incredibly knowledgeable from start to finish. He showed up on time, explained everything clearly, and fixed the issue quickly without trying to upsell unnecessary work. You can tell he genuinely cares about doing quality work and taking care of his customers. The whole experience was stress-free, and the plumbing repair in my bathroom was done perfectly. It’s hard to find reliable plumbers these days, but Leon exceeded expectations. I would highly recommend him to anyone looking for trustworthy and high-quality plumbing service.
