"Lockhart Electric has done several projects for me. Everything from replacing switches and fixtures to upgrading my breaker panel. They are always so helpful and knowledgeable. The prices are always fair, and they always give me options to help me make the best decisions depending on my need and my budget. I trust them with my home and I wouldn't call anyone else."

"When my HVAC unit went out I called A n 1 at 12:30am, as I have gotten home from work not too long ago. He answer and said he be right there. He came through check it all out and let us know exactly what needed to be done. He quote us too on the price if we decide to stick with him. Since he is a smaller personally owned company he didn't have financial options. So we had to think if over. Anyways I offer to give him some cash for coming out here so late and he kindly refuse, which was very kind of him. Even though it was already 2am by the time he was done checking it all out. After a few calls to other companies we realize we rather pay a hard working, honest man and help smaller local business. Also his price was unbeatable and the quote he quoted us was what we pay no hidden cost or anything. Needless to say we were highly satisfy with his work and his honesty. He was upfront with what was needed and didn't not try to sell us on anything else. Highly recommend his service! And the price was very reasonable!!!"

"With all the super hot days recently, our air conditioner wasn't able to keep up. Day 1 was able to get an almost immediate appointment and had us back up and running in no time. Very professional crew, and kept all pricing and repairs transparent. Would definitely use their services again."
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.
