"My fence had blown down in a recent storm and I didn't want my dogs getting out. All American came out promptly and gave me a quote that day and started the following Monday. The service was very well done and completed in one day. The owner was very polite and easy to work with. I am looking forward to them coming out and pressure washing my patio and decks. I would recommend this service."

"I recently had the pleasure of working with Miguel on several home improvement projects, and I cannot speak highly enough of his skills, professionalism, and dedication. Miguel undertook a range of tasks, including plumbing under the house, replacing the water heater, fencing, a bathroom remodel, and various bathroom repairs. From the outset, Miguel demonstrated exceptional knowledge and expertise in plumbing. The work under the house and the water heater replacement were executed flawlessly, with great attention to detail and a focus on quality. Miguel provided us with peace of mind and a reliable plumbing system. The fencing project was another testament to Miguel's versatility and craftsmanship. He meticulously planned and constructed a sturdy, aesthetically pleasing fence that not only enhances the security of our property but also adds to its overall curb appeal. Miguel’s eye for detail and commitment to excellence were evident throughout the project. Additionally, Miguel took care of various bathroom repairs with the same level of expertise and dedication. No job was too small for him, and he ensured that every detail was addressed, leaving us with a bathroom that is in excellent working order. Throughout all these projects, Miguel's professionalism, punctuality, and excellent communication stood out. He consistently went above and beyond to ensure that we were satisfied with the work, and his friendly demeanor made the entire experience pleasant. I highly recommend Miguel for any home improvement projects. His work is of the highest quality, and his commitment to customer satisfaction is unparalleled. Thank you, Miguel, for your outstanding work and for making our home a better place!"

"Working with Ilan Yosef in Los Angeles was an outstanding experience from start to finish. His team handled our full home renovation with precision, transparency, and professionalism. Every detail was discussed clearly, timelines were respected, and the craftsmanship exceeded expectations. It?s rare to find a contractor who genuinely cares about quality and customer satisfaction. Highly recommended for anyone looking for reliable remodeling services."

"He did a very good job. Be prepared for all of the extra's they will ask for beyond the initial deal. I will say we have a lot more airflow going through our heater now and the dryer really needed it. We had two cancellations before they came on the last time.

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
From average costs to expert advice, get all the answers you need to get your job done.
