"We bid the work to five different companies and not only did A-Anderson provide the best bid but they also included a new heating system as well which we had not considered replacing. The tech who came out to evaluate our A/C problem was knowledgeable but had a bit of an attitude. However, the office staff and the gentlemen who came out to install our new system were courteous and professional. They made sure that all carpet areas were covered and even sealed up the top of the utility closet, which we didn't expect them to do. We are going to need electrical work done in a few months and they will be our first call."

"Excellent. I can't say enough about how pleased I am with Southern Air Mechancial LLC for my Air conditioning service needs. Out of habit, I had been using another vendor who recently told me in the last 10 days that my unit was oversized for my duct work, that it was going to take 6 hours to fix it, and was about to sell me a part with installation and labor that would have cost $1400. The tech said it would break in a year and the owner basically tried to sell me a new AC unit. Got a little suspicious after asking if my unit could be adjusted since it was a variable speed down to a 3 ton and the owner said, "well, let me send my tech again". I called Southern Air and spoke to Clint, the owner. I had purchased the unit 7 years ago and without hesitation, Clint visited with his technician, and replaced the part that was a known problem with my manufacturer. He warrantied the part and was back out in two days and had the system cooling within 2 hours. I will only use Southern Air Mechanical and now know how trustworthy they are and what excellent service they provide. You can't and will not go wrong by choosing Southern Air Mechanical for your AC needs."

"I was just getting home from work and I happen to noticed that my house was really hot, the thermostat was reading 85 degrees while set for cool, the blower was working but my air conditioning system would not come on. I stepped outside and walked over to the system and heard a buzzing noise but nothing was working so I went on to my app and requested for an air conditioning company and Young and son stopped by the same day. Julius was able to diagnose the problem I was having with my AC system and explain the buzzing noise, within a short period of time my air conditioning system was working and providing my home with cold air. Thank you!!!!! So much young and son, I am going recommend your services to all of my friends and relatives."

"These guys are awesome!!!! I woke up at 8am Sunday morning in JULY and my AC WAS OUT! I called three other companies and they either did not answer or I left a message. When I called Metro AC Dewayne answered and told me he could have someone out today, he also explained their emergency call service fee of $150.00 but I totally understood since it was Sunday morning. He took my information and told me a technician would call me within the hour. Larry, the technician called me about 15 min later and said he could be there by 1000am. Dewayne called me back about 45 min later to make sure Larry had called me and set up a time. Larry showed up at around 950. I showed him where the compressor was and that it had been running but the fan had not been spinning. He looked at everything and came in and explained he felt it was only the capacitor but it might be the motor. His plan was the replace capacitor and if that didn't work we would change out the motor. He replaced the capacitor, checked the pressures and temps coming out of AC, changed out my air filter (which he did not have to do) and was done by 1100!! Larry was nice and used shoe covers and was very professional! Metro air conditioning will be my new go to AC and heating repair and maintenance shop!!"

"Mechanical Comfort Systems installed a new heating and air system when my upstairs (where all the bedrooms are located) system went out in the heat of the summer on a Thursday (left for work and it was working... got home and it was 90 degrees upstairs). I had another HVAC contractor out before calling Mechanical Comfort Systems and their proposal was significantly more expensive for a lesser system than I received from Mechanical Comfort Systems (the efficiency of the system was an upgrade from existing, and other company quoted replacement with same efficiency as existing). The system was replaced quickly (on a Saturday), and the installers were great, very professional. They cleaned up after themselves, and did a great job. During the freeze this February, I had a water pipe freeze and burst. Mechanical Comfort Systems came out the day after, even though driving conditions were still terrible and all my friends in similar situation were being told it'd be several days to a week before a plumber could come unless they paid some ridiculously expensive emergency fee... I recommended Mechanical Comfort Systems to three other people I knew that also had frozen pipes burst, and they all had them come after fix theirs after I gave them Mechanical Comfort Systems information. I strongly recommend Mechanical Comfort Systems to anyone needing any plumbing or HVAC work. I'll definitely use them again... although I hope not anytime soon ?"

"Dr. Air & Heat was fast and efficient. We had a whole new system installed the same day! They put down drop cloths on the path to the A/C unit then vacuumed up the bits and pieces with a shop vac. Then they requested the use of my “regular vacuum cleaner” to finish the clean up!!! Three got my vote."

"I had them clear my condensate line on my AC. They showed up on time and did that work sufficiently. All is good on step one. The issue arose when I asked them to do a full maintenance check on my AC/furnace since I had been having intermittent issues with my heating coming on. And, unsurprisingly, they said that the repairs would have been in the thousands of dollars and my only realistic option would be to replace the whole unit. A few days ago I was able to completely resolve my heating issues by Googling the problem and subsequently doing a manual re-start on my Nest smart thermostat. Problem resolved by a flip of the switch and I saved 3K+ dollars by not listening to their expert advice. So, my only recommendation to anyone reading this is to ensure that when you hire big commercial AC company repair companies like Enoch, go into it with your eyes wide open. They do not pay a bunch of money for leads because they want to repair your system. That is simply the excuse to get their foot in the door. They want to find an older unit and sell you a new AC unit every time if possible. That is where the big bucks are in this business, not in repair. By and btw, I am confident that they would do a great job installing new systems. But there is little regulation of this industry and no incentive for them to just fix the issue and buy you another few years when they could cash in by telling you that your issue is beyond repair. Notice how most of their reviews here are about installing new units. That is because that is primarily what they advise everyone to do; And people trust them. Here is my expert consumer advice: 1. NEVER buy an AC/heat pump from the initial company that comes out to repair the unit and then tells you that you have no choice but to replace your unit. All you are doing is incentivizing bad behavior. 2. Get a second opinion from another AC company. If they diagnose the exact same thing, then ask for a full replacement bid. Then, advise them that they are competing. 3. Come back to Home Advisor and post that you need a new AC/heat pump and provide the exact size and model number. Then collect the bids, check previous reviews to ensure the company is reliable, and then select the most inexpensive offer. If you make them compete, you will typically save somewhere between 30-40% of replacement costs. Good luck but BUYER BEWARE."

FAQs for furnace / forced air heating system install or replace projects in Sunnyvale, TX

Converting from an oil furnace to an electric furnace isn't a simple swap—the oil system needs to be completely removed before installing the electric furnace. You'll need a full electric system installation, but you might be able to reuse existing ductwork if it's up to current safety standards. You’ll need to budget for a new electric furnace installation, which costs between $1,800 and $6,200, including professional removal, proper disposal, and safe installation of the new system.

Electric furnaces are 100% efficient at converting electricity into heat. However, some of that heat can be lost as it travels through your home's ductwork or escapes through poorly insulated areas. That's why regular duct maintenance and proper home insulation are important to maximize your furnace's efficiency and reduce heat loss, ensuring consistent warmth and lower energy costs.

With proper maintenance, an electric furnace can last anywhere from 20 to 30 years, outlasting the average gas furnace's lifespan of 15 to 20 years. To keep your electric furnace running efficiently, schedule regular cleanings, tighten connections, and have inspections done before winter arrives. With routine maintenance, you’ll ensure consistent, safe heating for years to come.

The size of the electric furnace you need depends on factors like your home's square footage, climate, and insulation quality. As a general guideline, those who live in warmer climates should multiply their square footage by 30 to 35 BTUs, while those in cooler areas should multiply it by 50 to 60 BTUs.

Consulting with an HVAC professional can help you determine the exact size that's right for your home.

An electric furnace works by converting electricity into heat using high-resistance heating elements. A blower then pushes the warm air through your home's ductwork, distributing heat evenly throughout your space. Since there's no combustion involved, electric furnaces eliminate the risks associated with gas furnaces and provide consistent, reliable heating when properly installed.

An electric furnace uses between 40 and 80 kilowatts per day to heat your home. The exact amount it uses depends on factors like your home's size, insulation, and overall energy requirements. Larger homes or those with poor insulation use more energy than smaller, well-insulated spaces. A professional furnace assessment can help confirm the ideal unit size for your needs.
