When things go awry with your Caldwell home’s HVAC or electrical system, we’re the company to call. Flickering lights due to mini-power surges are a common concern. You might have GFI outlets that constantly trip or won’t reset. The standard wall outlets in your Caldwell home could have singe marks or emit the faint, sweet smell of burnt wiring. Allowing issues like these to fester sets the stage for fires and undermines the value and safety of your home. No matter which signs of electrical trouble manifest, immediately scheduling electrical repairs is essential.

You should also seek immediate assistance if your heater or air conditioner isn’t doing its job efficiently or won’t turn on. With timely HVAC services, you can extend the lifespan of your heating and cooling equipment, maintain reasonable home energy bills, and enjoy optimum temperature and humidity control year-round.


When the time comes to add new appliances or other electricity-powered features to your Caldwell home, you’ll need the help of a seasoned electrician. This is especially true if you own an older, historic property that isn’t wired to support current electricity demands.

Whole-house rewire services for homes with outdated electrical systems can enhance the performance and increase the efficiency of modern appliances, such as:
  • Lighting plans
  • Security systems
  • Refrigerators
  • Washing machines
  • EV charging stations

If you’ve recently refinished your basement, turned your attic into a functional bedroom, or converted a spare room into an office or home gym, you may need to add wiring, outlets, and other electrical features to support this space. You’ll also want to add climate control to these spaces. A ductless mini-split system could be just the answer you’re looking for.

Maybe you require a new HVAC system or need to replace your old one. Most heaters and air conditioners have an average life expectancy of 15 to 20 years. Replacing an aging unit with a high-performing and efficient model can slash your monthly utility bills. It may also help you be more comfortable in your home.


You may need maintenance services for your electrical or HVAC system to remain compliant with the terms and conditions of your home insurance plan and home warranties. You don’t have to wait for your outlets to spark before hiring an electrician. Circuit breaker boxes should be replaced every 25 to 35 years, and residential rewiring services should be scheduled every 20 to 25 years. If your home still uses fuses rather than a circuit breaker box, your time for electrical system maintenance is long overdue.

Your heating and cooling equipment requires regular maintenance, too. To comply with HVAC manufacturer warranties, heaters, and air conditioners must receive professional service every year.

At A-1 Heating Air Conditioning & Electric, we’re honored to serve the residents of Caldwell and the surrounding communities. For over 60 years, we’ve consistently provided superior workmanship and unbeatable customer service. We always offer clear and easy-to-understand estimates and invoices. We perform all of our HVAC and electrical work to local building codes. With our HVAC services, you’re guaranteed to get accurate sizing, convenient installation, and lasting value from your new heating and cooling equipment.
