"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."

"We scheduled a 4 pm appointment. By 4:45, no one showed up or called to confirm their whereabouts. I had to call Metro Air and ask what was going on. The secretary said she will dispatch a technician to my house. The technician did not arrive until 5:30. He was kind and was able to fix the capacitor, which was causing the issue. About a week later, their office followed up. I told the lady that the a/c was on, but now there was another sound coming from the system. The secretary indicated that the technician would call me that day to discuss and set up a follow up visit to address the issue. No one ever called."

"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."

"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."

"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."

"The lady that answered the phone was very polite and scheduled the appointment to my convenience. The tech. Arrived 10 mins early and presented himself very professionally also his van looked very nice. Upon diagnosing the problem he explained all my options and gave me his recommendation as to what my next step should be. I decided to replace bad part and get the air conditioner tuned up. I'm was extremely satisfied with the level of service I received from mechanical comfort systems, and will use the company again for future repairs and maintenance.

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.
