“Jacqueline and Adam came over and showed me a lot of the deficiencies. On my ductwork that I did the whole house there was a lot of places the tape was not missing and also the air conditioning unit heater was completely off, but no duct tape. Adam Jacqueline was so nice that they taped everywhere. I need to tape that Hometown didn’t do that was supposed to do they did it for free. I definitely will use them from now on until I sell this house. I’m very disappointed with Hometown heating and air plus the person that came over was not a nice person at all Jeffrey did the estimate . I will not use them again ever.”

When your HVAC system breaks down, you need fast, reliable service that gets things back to normal. Our repair specialists diagnose problems accurately and fix them right the first time. We stock common parts on our trucks, which means most repairs happen the same day you call us.
Strange noises, uneven temperatures, or systems that won't turn on all signal different issues that require different solutions. We start every repair job with a thorough inspection to identify the root cause and prevent future breakdowns. Our goal is simple: restore your comfort as quickly as possible while making sure the repair lasts.
Summer in Northern California can get uncomfortable if your AC decides to take a break. When your unit starts blowing warm air or your energy bills spike for no clear reason, it’s time for professional AC repair.
We dig into everything from clogged filters to refrigerant leaks, finding the root cause before offering realistic repair options. In most cases, we can get your air conditioning back in action that same visit. Even older systems get a fighting chance when we step in to diagnose the issue properly.
Heat pumps are versatile systems that provide both heating and cooling, making them a popular choice in our moderate climate. However, if you're experiencing issues like a pump that's stuck in one mode, making grinding noises, or simply not changing the temperature in your home, it's time to call in an expert.
Our technicians have the specialized knowledge to work on these sophisticated systems. They will get your system back to efficiently warming and cooling your home, ensuring your comfort no matter the season.
Cold mornings and chilly evenings remind us how important reliable heating really is. Our heater repair specialists work on all types of systems, including gas furnaces, electric heat pumps, and radiant heating.
We provide prompt furnace repair in Pleasant Hill, CA, because we know heating problems can't wait. Pilot light issues, thermostat malfunctions, and blower motor problems are common fixes we handle daily. We also service heat exchangers, gas valves, and ignition systems to keep your heating system running safely and reliably.
Installing a new system or replacing an older one brings lasting comfort and better control over indoor temperatures. We help customers choose setups that fit their homes, budgets, and lifestyles.
Our process encompasses a complete inspection, load calculation, and walk-through to make sure you know exactly what you're getting. No hard sells, no pressure, just honest recommendations based on years of experience with Pleasant Hill’s climate and energy usage trends.
Upgrading your cooling system can bring better airflow, lower bills, and quieter operation. We handle AC installation in Pleasant Hill, CA, for traditional split systems and ductless mini-splits alike.
Ductless units work great for older homes or additions that don’t have space for ducts, while central systems still make sense for larger homes. We install equipment from trusted brands and make sure every step, from placement to thermostat integration, happens seamlessly.
If your current system has been pushing past its limits, now might be the right time for an upgrade. Reach out now for AC installation that will keep you cool for years to come.
Staying warm during the colder months isn’t just about comfort—it’s essential. If your heating system is outdated or inefficient, it may struggle to maintain a consistent temperature and could drive up your energy bills in the process.
We're masters in both heater installation and replacement, offering modern solutions to keep you cozy. We can help you explore a variety of options, including high-efficiency furnaces and versatile heat pumps that provide both heating and cooling in one unit. Our expert technicians will ensure your new system is installed correctly and safely so that you can have a dependable source of warmth all winter long.
Hot water keeps your daily rhythm running until it stops without warning. When the water turns cold or takes forever to heat up, that’s where we step in. Our team works on both gas and electric water heaters, including tank and tankless models.
We'll take a close look at the system’s parts, like the burner, thermostat, pressure valve, and electrical connections, to figure out what’s going on. Common issues can include sediment buildup, pilot light trouble, or worn-out components. If it looks like your water heater’s on its way out, we’ll walk you through the replacement options that suit your home.
Your thermostat is the command center for your HVAC system, giving you direct control over your indoor climate. We can help you with calibrating your current and upgrading to a new, programmable, or smart model.
Beyond thermostats, we also offer a suite of indoor air quality services. The air inside your home can be affected by dust, pollen, pet dander, and other allergens. We can assess your home's needs and recommend solutions like advanced air filtration systems, humidifiers, or dehumidifiers to help you create a healthier living environment. Proper ventilation is another important aspect of indoor air quality, and we can inspect your system to make sure there is adequate air exchange. Our goal is to help you achieve total home comfort with clean air and precise temperature control.
